Dalton " OSO" T orqu e Limiters give longer life for the foll ow ing reasons:
1- High ca rb on steel hub
5-Chrome vanadium steel Belleville springs
2- Steel pressure plate
6- Single hex nut of alloy steel for uniform torque
3- Precision machining
7 - Ratings based on a safety factor of 33%
4- Roller Bearings
B- Sprockets ground to approximately a 32 micro inch finish
These features add up to better performance and longer life.
No other torque limiter can equal the performance and long life.

DALTON MODEL "OSDC"
OVERLOAD SAFETY DEVICE
The Dalton OSDC (Overload Safety Device Coupling) provides overload
protection through the use of an OSD unit combined with a roller chain
coupling half counterbored to fit the OSD flange . Standard double-width
roller chain is used to couple the basic OSD unit and the coupling half.
The OSDC can be set with a torque wrench for maximum load
desired. The unit functions as a roller chain coupling until an overload
occurs, causing the OSDC to dis-engage. The device is automatically
re-engaged when the overload is eliminated.

MODEL ttROSDC"
RIGID OVERLOAD SAFETY DEVICE COUPLING
The Dalton ROSDC ( Rigid Overload Safety Device Coupling) provides overload protection through the use of an OSD unit combined
with a rigid coupling half counterbored to fit the OSD flange. AIIsteel rigid coupling half is bolted to a basic OSD unit to form a rigid
coupling with the overload feature.
The ROSDC can be set with a torque wrench for maximum load
desired. The unit fun ctions as a rigid coupling until an overload
occurs, causing the ROSDC to dis-engage. The device is automatically
re.engaged when the overload is eliminated.

The Dalton Roller Chain Shear Coupling (RCSPC) has an
accurate torque release obtained by precision machining of the
shear pin neck diameter and material used .
The maximum capacity in inch pounds is up to five times greater
than the rated capacity of friction type torque limiters.
When loads occur beyond the rated capacity. the p in shears at
the neck . A new pin when installed allows operation 01 the
equipment with no damage to any part , mechanical or otherwise. The pin must be replaced w ith a Dalton Shear Pin or
equivalent as shown in the catalog .
Maximum capac ities range from 738 inch pounds to 66.504 inch
pounds.
Gear Shear Pin Couplings (GSPC) are available to order.
Our engineering department is available for more information or
when stock sizes do not suit your needs.

Turns off power source at pre-set load limit
The Dalton SOS Safety Overload Switch is designed specifi·
cally to insure against breakdowns in all types of driven
machinery by providing automatic shutdown at the precise
moment an overload occurs.
The proven reliable SOS Safety Overload Switch reduces
downtime and production loss in medium and heavy duty
chain driven systems by shutting off power before excessive
torque can cause costly damage to mechanical com ponents.
One model ca n accommodate chain drives of % ·inch pitch
#60 chain to 2·i nch pitch #160 chain. A final spring adjust·
ment screw permits rapid , easy pre-setting for maximum
desired load regardless of chain pitch and size.
The Dalton SOS Safety Overload Switch is effective. eco·
nomical insurance against heavy·duty chain drive overloads
in a wide ran ge of applications.
14
HOW IT WOR KS
The SOS ball beating sprocket assembly is mOloted as an idler on the
tight side of the chain drive. It can be set on top or bottom of drive chain,
whichever is the tight side. As the load increases, the arc of the chain
becomes straight. and the spring tension on the fulcrum arm resists this
force until a pre·set torque is reached . When the pre· set point is reached ,
the spring opens a micro switch that shuts off power from the motorstopping the drive system. Sta rting torque generally determines th e
maximum load for proper spring tension adjustment. One half inch to
one inch of chain deflection is required to activate the limit switch. When
overload has been eliminated, the ci rcuit will close and the motor can be
re·started with a push button.
