DIAMOND CHAIN HISTORY
(317) 638-6431
Arthur C. Newby, Edward C. Fletcher and Glenn Howe, with a $5,000 investment, started
what was to become the Diamond®Chain Company by forming The Indianapolis Chain &
Stamping Company on December 24, 1890. They took the diamond as their
trademark because it symbolized perfection and acted as a constant
reminder of their endeavor.
In its humble beginnings, The Indianapolis Chain &
Stamping Company (IC&SC) specialized in bicycle chain. As
one of the first companies in the United States to produce
bicycle chain, IC&SC prospered, outgrowing its original quarters and moving to larger facilities in 1892.
In 1901, when the bicycle chain business slumped, IC&SC
rebounded by developing and introducing to industry a twinroller roller chain.
From December 17, 1903, when Diamond chain was used on
the Wright brothers’ first flying machine, to the present, Diamond Chain has been
a major supplier of chain not just for aircraft, but for power transmission and product conveying throughout manufacturing industries.
In 1950 Diamond Chain was acquired by American Steel Foundries, Inc. – the largest steel
foundry in the world, and in 1962 the name of the parent company was changed to AMSTED
Industries Incorporated.
During Diamond’s many years of producing the highest quality roller chain they have tested,
examined and discovered many developments which have significantly increased the performance of their roller chains. These developments have rarely become “product lines” but
rather, “product improvements” which have been incorporated into daily
production so that all customers can benefit, without special requests
or premium prices.
In addition to continued product improvement, Diamond
has introduced a detailed roller chain Drive Selection
Software program. This software will improve the way chain
is specified by engineers and designers by simplifying a
multitude of sometimes difficult calculations and equations.
In today’s environment, Diamond, while focusing on
the increased use of technology, still operates under the same

inventive, grassroots philosophy it was founded on – providing its customers
customers with a high-quality product possessing the best balance
with high-quality product processing the best of performance, reliability
price and delivery that meet or exceed their requirements.
If you’re looking for the best roller
chain for the job, it’ll pay to take acloser
look at Diamond roller chain. Diamond roller chain may look
like your everyday chain, but upon closer inspection the unique
differences that make Diamond chain better become evident.
From the strict attention to detail we devote to every chain
design, to the extra steps we take during fabrication and assembly operations, those differences really add up. We build long
life, lasting value and enduring customer relationships into every
link of chain...that is the Diamond difference.
Over the years we’ve produced tens of thousands of types of roller chain
for a wide variety of applications from oil field and deco ovens,
to conveyors and combines. So, if your application calls for some
special attention, our application engineers can easily help you
find that lasting solution.
Please, take a closer look at Diamond roller chain...we do.
That closer look is what makes ours better than other chains.
And what you can’t see, you can experience with improved
performance – which means less downtime, less repair costs,
and increased productivity. Those are just
some of the differences that a Diamond chain makes.
ISO 9001
Building high-quality roller chain is a matter of demanding
precision – a matter of establishing critical parameters, both in
component fabrication and final assembly, and monitoring them
to ensure that they are maintained.
ISO 9001 certification is awarded to companies that develop,
and consistently adhere to, a well-documented quality system. ISO 9001 requires compliance
with 20 elements, some of which include customer
service, contract review, manufacturing procedures, and product design and
development. Diamond is ISO 9001 certified. That means you can be sure that Diamond chain
is consistently manufactured following detailed processes developed by Diamond and proven to
produce some of the longest running and best performing roller chain.

Each component of a Diamond chain is engineered and produced with optimum performance in mind. Exacting specifications cover critical properties of all component parts and

assemblies. Diamond’s ISO 9001 certification is proof of the fact that “we say what we do and do
what we say.”

but additionally these models are subjected to performance testing in accordance with API
(American Petroleum Institute) Specification 7F. Only those companies which have established
quality systems, approved and routinely audited, are authorized to display this symbol.
CHAIN COMPONENTS
Roller chain is not that hard to understand. It is normally made up of five components:
Collectively, these components produce a series of “traveling bearings.” To accomplish this, the chain
is assembled with alternate inside and outside links. The inside links that employ bushings and/or rollers are called roller links, and the outside links that employ the pins are
called pin links, or connecting links. In operation, the pins articulate inside the bushings leaving the rollers free to turn on the outside of the bushings for
“rolling” action as the chain enters and exits the sprocket.
Every Diamond chain is made from the highest quality raw
materials available. Starting with the proper raw materials is the
foundation of any quality product. Diamond pays close attention
to chemistry and dimensional specifications which are critical factors as the material is transformed into components capable of
handling the toughest job. Producing these components requires
painstaking attention to detail and control of fabrication, heat treatment, finishing and assembly processes. Other chain manufacturers
may do a good job in some of these areas but at Diamond, we consistently do it better in all.
Nothing Outlasts a Diamond.

MANUFACTURING PROCESS
Diamond jewels are sought out because of their
enduring perfection. The same argument can be made
for a Diamond chain. But, unlike precious gems,
Diamond chain is readily available directly from us or
your authorized Diamond distributor.
The process of manufacturing the longest lasting chain
begins by purchasing the materials to our detailed specifications.
Bushing Orientation
We do this because we must specify chemistry, dimensional size and
even the direction of the grain in order to fabricate components capable of performing to
your expectations.
Transforming these raw materials into individual components that meet our high standards is no easy task. Again, we’ve learned that attention to detail is a key to achieving the
desired result, which is the user’s
satisfaction. Some of the steps taken to provide this satisfaction are:
Link plate pitch holes are produced using a three-part process to
create a polished hole with maximum bearing area and minimal surface
imperfection. Maximum bearing area increases chain integrity, and a
smooth surface within the pitch hole maximizes the ability to handle heavy loads,
especially in fatigue-sensitive applications. Even with the threepart process,
link plates are left with a small “breakout” area. To minimize the
effects of this, Diamond provides a unique identifying feature on
our 19.10mm through 57.20mm pitch, standard and heavy series
ANSI chains. This identifying feature, a beveled edge, is unique to
Case Hardened Pins
Diamond, and we use it to orient and assemble the link plates in a direc-
tion which minimizes negative effects of the breakout.
Many years ago, Diamond discovered that forming bushings and rollers from strip produced a far superior component, particularly when the chain operated in an application that
subjected it to bushing/roller fatigue. Diamond also developed processes which orient the
chain bushings to position the seam away from the load bearing
surface. Positioning the bushings results in a smoother, more uniform bearing surface and
helps to reduce chain length variation. In 6.40mm through 31.80mm pitch ANSI chains, our
standard
6
(317) 638-6431
bushings and rollers are produced using this method. This is
because in these sizes horsepower is
most often transmitted at higher speeds with relatively low
loads.
Beginning with 38.10mm pitch, Diamond provides
solid rollers because in the majority of
applications horsepower is transmitted using higher loads
and lower speeds. Under these conditions the integrity of a
solid roller is beneficial and therefore, it is provided. There are, of
Shot Peening
course, exceptions to these standards and depending upon the specific
conditions, solid rollers are available either by design or customer request.
To most users, the obvious indication of quality is superior wear life. Poor wear life often
leads to regular adjustment or replacement, which reduces productivity and adds cost to an
operation. Heat treatment of component parts is an additional procedure to prolong wear
life which gives them the ability to perform to their optimum, depending upon what the
environment may be. In the vast majority of applications, wear life is critical, so Diamond
heat treats those components which control chain elongation very carefully.
Virtually all of our standard pins, bushings and rollers are carburized, or case hardened.
This closely controlled process transforms the outside of the parts into a hard, wear-resistant
surface
but allows the inner core to remain tough and ductile so as to absorb
normal shock loading.
In most applications this combination provides the perfect balance between wear resistance and durability.
Link plates, on the other hand, are not normally subjected to wear but must be tough to resist
the loads, sometimes heavy, to which the chain may be
exposed. Their heat treatment is designed
to produce tough, ductile and shock-resistant properties, but
sometimes heat treatment is not enough. For those sizes that are rou-
Preloading
tinely subjected to heavy or shock loads Diamond further conditions
the link plates using a process called “shot peening.” In this process, small steel pellets, or
shot, are propelled at the link plates. When they strike the surface they leave
a tiny indentation which causes the material to work harden. This work hardening creates
compressive stresses on the surface of

the link plate that allows it to resist, beyond conventional heat
treatment, premature fatigue failures.
The attention to detail that goes into the fabrication of component parts is not forgotten
when assembly operations begin. During the assembly of every pitch of Diamond chain, four key
components (pin, bushing, pin link plates and roller link plates) are examined carefully. These
four parts are critical in maintaining chain integrity and controlling chain length. Sections of
chain are tensile-tested for conformance to Diamond’s specifications which are greater than
those specified by ANSI, The American National Standards Institute. Sub-assemblies are evaluated, too, for both pin and bushing press-out force. Holding-power tests are done to ensure that
the sub-assemblies are of the highest quality and will not become the “weak link” in the chain. All
this “self inspection” allows us to examine how the parts work separately as well as together.
And, when new components are added during assembly, additional tests are
performed to ensure the integrity of the complete chain remains unchanged.
Diamond even identifies our chains with a unique code, we call it a “date stamp,” that is
applied during assembly. This code gives us information about the components used to produce
the chain. This means that Diamond Chain has traceability as to the material used to produce
a component, fabricated on a specific piece of machinery, heat treated in a specific furnace and
finally, assembled on a specific date. That’s a significant feature that other chain manufacturers
just don’t have.
One might think that assembly is the final step in producing a product, but at Diamond we
still have a couple of things left to do. After the chains are assembled, we apply an initial load to
the chains, called preload. This loading approximates the recommended loading a chain can
expect in service. Preloading is done to align the various chain components such as pins, bushings and link plates. Preloading helps eliminate initial elongation and can increase the usable
service life of your chain.
We even subject our own product to performance testing at conditions well beyond recommended limits. Tests on link plate fatigue, roller/bushing fatigue and initial lubrication wear are
performed to search out the chain’s endurance limits. This “torture testing” allows us to set rec8

The same roller links are used for single and multiple strand
chains.
The two pins and one link plate are furnished
assembled. The coverplate may be either press-fit
or slip-fit on the pins. Press-fit connecting links are recommended for heavy duty applications. Press-fit coverplates are
standard on multiple strand oil field chains.

Press-Fit
Type For Single Strand
Chain Only
This type of assembly is available for all sizes of
standard single strand chains, and consists of an
offset link and a roller link assembled together. The
pin is press-fit in the offset link plates and is riveted.
The press-fit construction of this assembly greatly increases
its structural rigidity, reliability, and durability. For these reasons, the two-pitch offset assembly
is recommended in preference to the single-pitch
offset link.
Single-Pitch Offset Link Slip-Fit Type
This link is furnished with slip-fit pin unassembled
in the offset link plates. The flat milled on one end
of the pin prevents it from turning in the link plate.

HEAVY SERIES CHAIN
Chain Descriptions and Dimensions
Heavy Series Chain
Heavy Series chains, also built in accordance with ANSI B29.1, are designed using link plate material from
the next larger size chain. Heavy Series chains are not necessarily stronger than Standard Series chains, but the thicker link plate
material provides an increase in fatigue resistance for those drives subjected to heavy shock loads, multiple stops/starts or reversing.

HIGH STRENGTH/LIFT CHAIN
Chain Descriptions and Dimensions
(317) 638-6431
Produced in accordance with ANSI B29.1, these chains are designed for the rigors of heavy loads and lifting. Depending on your
specific application, Diamond offers three options from which to choose.
High Strength (HS) Drive Chains
HS Series Drive chains are built in accordance with ANSI B29.1 and are dimensionally identical to Heavy Series Drive chains, but
are specially designed and incorporate pins produced from medium carbon alloy steel. These pins are through-hardened to give
the chain a higher working load capacity and additional resistance to fatigue in high load and pulsating type applications. Users of
these chains should remember that wear life may be slightly reduced due to the material and heat treatment of the chain pins.
Slip-fit type connecting links and offset links are not available for these chains.
Note: Offset links and slip-fit connecting links are not recommended for any High Strength or Lift Chain.

Hoist Chain
These chains are built in accordance with ANSI B29.24 and are dimensionally identical to Standard Series Drive chains, but also
incorporate pins produced from medium carbon alloy steel, through-hardened, to give the chains higher working load capacity and
additional resistance to fatigue. Additionally, these chains are produced with solid rollers for increased performance when loading
is high, but speeds are slow. Users of these chains should be aware that wear life may be slightly reduced due to the material and
heat treatment of the chain pins.
Note: Slip-fit type connecting links and offset links are not available for these chains.

SPECIAL LUBRICATED CHAIN
Chain Descriptions and Dimensions
RING LEADER®O-ring Chain
Diamond’s RINGLEADERO-ring chain is specifically designed for applications that don’t permit regular lubrica-tion, requiring the
chain to depend entirely upon initial factory lubrication throughout its service life. Depending upon the specific conditions, RING
LEADERcan provide up to ten times the wear life of standard chain.
Industries such as agriculture, food processing, packaging, printing, textile and chemical processing can
introduce contaminants that damage standard chain. Dirt, mud, food particles, paper fines, dust and moisture can cause buildup
on the chain and clog the openings on standard roller chain where lubrication enters the pin/bushing area. These contaminants
can even get inside the chain, actually damaging the surface of pins
and bushings.
RINGLEADER O-ring chain is constructed with O-rings that seal a specially formulated lubricant into every joint. This sealed-in
lubricant is essential for the chain’s optimum wear life and the O-rings also help to seal out
and protect the internal surfaces from dirt, contaminants and moisture. Diamond recommends that RING LEADER O-ring chain
receive periodic external lubrication to maintain moisture on the external O-ring surfaces and to
lubricate roller/sprocket contact surfaces. Note: Standard RINGLEADER O-ring chain can routinely operate in ambient temperatures up to 66° C. For higher temperature requirements, special O-rings can be substituted, allowing operation in temperatures of
206° C or greater.
■
O-rings keep lubrication in and contaminants out.
■ Special bushings, having very uniform wall thickness, are precisely heat-treated to obtain an optimum balance
of strength, wear resistance and toughness. The bushings are extended beyond the roller link plates. This feature helps the
O-ring stay in position and provides maximum pin support, resulting in greater bearing area for the pin.
■ Pins are made from a special alloy steel and are hardened and centerless ground. Rigid quality standards
ensure precise hardness control for high wear resistance and toughness.

Because the RING LEADER chain lasts up to ten times longer than regular chain, overall economy of operation is improved. With
lubrication already sealed into the chain, maintenance expense is lowered. RINGLEADER O-ring chain experiences less wear
elongation during normal operation, thus providing a longer service life. Life cycle costs of RINGLEADERchain can be dramatically less than for standard chain in certain applications which translates into longer lasting roller chain and a real cost savings.

SPECIAL LUBRICATED CHAIN
Chain Descriptions and Dimensions
When the environment or location of your roller chain drive is such that regular lubrication is not possible or practical, consider
Diamond Chain’s Special Lubricated chains. Diamond offers two types of Single- and Double-Pitch Drive or Conveyor chains
designed specifically to deliver the highest level of performance– even in applications that can’t, or don’t receive proper lubrication.
DURALUBE®Chain
For applications where regular lubrication is a challenge, DURALUBE can offer a longer lasting solution. This chain
is constructed using a one-piece powdered metal bushing/roller combination which has lubricant drawn in under vacuum. In service, this lubricant is released and provides supplemental lubrication to the pin/bushing joint between regularly scheduled maintenance. Generally, the wear life of DURALUBE chain can be five times that of standard (initially lubricated only) chain.

Nickel-Plated Chain
Diamond Chain produces a full line of Nickel-Plated roller chains for a variety of uses in environments where the chains are
exposed to moisture. Common uses include applications exposed to the weather, high humidity or those on machines that are frequently washed down with water.
Diamond Nickel-Plated chain is different from many rust-resistant chains, because Diamond electroless nickel plates all of the
components before assembly, virtually eliminating the possibility of stress-corrosion cracking.
Pre-assembly plating also ensures all components are plated, which prevents internal rust from seeping out and causing contamination.
Note: These chains are not intended to resist corrosion from caustic chemicals or acids. For those types of
applications, stainless steel chain is recommended.

CORROSION/MOISTURE
RESISTANT CHAIN
Chain Descriptions and Dimensions
Stainless Steel Chain
Diamond produces a wide range of Single-Pitch Drive and Double-Pitch Conveyor chains manufactured in four combinations of
stainless steel depending upon the specific application.
AP Stainless Chain:This chain is assembled using 300 Series (austenitic stainless) link plates, bushings
and rollers along with a precipitation-hardened stainless steel pin. This combination increases the wear life of
this chain over those constructed entirely of 300 Series components. AP Stainless chains are well suited for
food processing, and are approved by the Food and Drug Administration. AP Stainless will be supplied unless otherwise specified.
300 Series Stainless Chain:These chains are assembled entirely from 300 Series (austenitic) components. They
have excellent corrosion resistance and very low magnetic permeability but cannot be expected to have the same wear resistance
of our heat treated stainless chains. For industries that require it, 300 Series chains can be considered “non-sparking.”
400 Series Stainless Chain:These chains are manufactured using 300 Series link plates but have pins,
bushings and rollers that are produced from 400 Series (martensitic) heat treated stainless. This combination
significantly increases wear resistance over those that are constructed using only 300 Series stainless chains.
The properties of the 400 Series heat treated parts may, in some instances, cause them to discolor when in
contact with certain chemicals.
600 Series Stainless Chain:These chains are assembled using 300 Series link plates, with pins, bushings and
rollers made from 600 Series (17-4/17-7) precipitation-hardened stainless.

Attachment Hole Sizes
Diamond’s attachment hole sizes are sometimes unique. Diamond has such a long history of producing roller chain that many of
our attachments were designed long before any standardization was adopted throughout
the industry. We continue to produce our most common attachments with holes to accommodate the following screw sizes:

ATTACHMENT CHAIN
CONSIDERATIONS
Chain Descriptions and Dimensions
Assembly:While it is possible to purchase base chain or attachment components and construct an attachment chain, it is
strongly recommended that chains be ordered and assembled at the factory to ensure the proper fit and alignment of all parts
along with any length or matching requirements.
Manufacturing Length Tolerance:ANSI defines the permissible length of an assembled section of
roller chain. The allowable length tolerances vary from model to model and are also affected by the chain’s
construction, i.e., with or without attachments.
As an example, the assembled length tolerance for an ANSI one inch pitch chain (#80) is + 1.33mm/-.000mm
per meter. When attachments are added to the chain’s design, the tolerance for length expands to + 2.66mm/
-.000mm per meter. This means that a section of #80 chain 12 pitches long (304.8mm nominal) can measure as long as
305.206mm but no less than 304.8mm. The same section of chain assembled with bent, straight, or extended pin attachments
could measure as long as 305.6mm but again, no less than 304.8mm.
In common practice, manufacturers strive to produce chain nearer to the nominal figure, but the maximum allowable length tolerance should always be considered when designing for take-ups and catenary chain sag. If the application requires it, some design
and assembly steps can be taken to direct the length of the chain toward the nominal. However, on a routine basis machine
designs based on a nominal or specified chain length should be avoided.
Length Matching of Roller Chains:Many applications require two or more chains, normally with attachments, to
run in parallel with “flights” joining the chains together forming a conveyor or transfer type system. In these cases it is critical to
have the chains ordered as a set, matched for length and installed on the machinery with the same relationship to one another as
when they were manufactured.
Diamond offers two degrees of matching for parallel operation:Class I and Class II
Class I -A Class I match assures that the longest and the shortest chain in a given set will not vary in overall length by more
than .500mm/m. Again using #80 chain as an example, the length of two #80 chains 120 pitches long will not vary by more than
1.524mm in overall length (3.048m x .500mm/m = 1.524mm). The shortest
could measure 3048mm + .000mm (remember, no negative tolerance) and the longest could measure up to 3048mm + 1.524mm
and satisfy the Class I requirement. Class I matching is most often accomplished by assembling the chains from selected lots of
component parts.
Class II -A Class II match is much more stringent and assures that the longest and the shortest chain in a given set will not
vary in overall length by more than .167mm/m. Applying this new tolerance to the above example,
the length of two #80 chains 120 pitches long will not vary by more than .508mm in overall length (3.048m x .167mm/m =
.508mm). The shortest could measure 3048mm + .000mm and the longest could measure 3048mm + .508mm and satisfy the
requirement. Class II matching is quite difficult and requires some very
unique procedures.
Differences -It is important to remember that matched chains still fall under the overall length limitations imposed by either
ANSI or the manufacturer. Matching does notassure the user of chains with a finite overall length, only that the chains in the
set have a controlled relationship to one another.
