Belt drive selection procedure
Poly Chain® GT2
Features and Benefits
Before designing a Poly Chain® GT2 synchronous
belt drive, you need to determine following drive
requirements:
1.
2.
3.
4.
5.
power requirement and type of driveN machine
the rpm of the driveR machine
the rpm of the driveN machine
the approximate centre distance for the drive
hours per day operation
To select a Gates Poly Chain® GT2 belt drive, you
need to complete the following steps:
STEP 1
CALCULATE THE DESIGN POWER
Design power = service factor x power
requirement
A. To calculate the design power it is necessary to
determine the service factor for the drive.
Determine the type of the driveR machine using
the service factor chart.
B. Using the service factor chart, determine the
service factor for the driveN machine and the type
of operational service.
C. Multiply the power requirement of the drive by
the service factor you have selected. This gives
you the design power for use in designing the
drive.

Features
Poly Chain® GT2
Tratrix Tooth Form
• The belt’s teeth and body are made of a lightweight
polyurethane compound, specially blended for adhesion
to the cords and fabric. This uniquely formulated
polyurethane makes the belt tough and virtually immune
to abrasion and chemicals.
• The aramid tensile cords provide extraordinary power
carrying capacity. Flex fatigue life of aramid is
exceptional, and its high impact strength withstands
shocks and surge loading.
• The fabric covering the teeth is highly resistant to oil,
chemicals, pollutants, corrosion and abrasion. It is
exceptionally durable and remains fully operational under
extreme temperatures from -54°C up to +85°C. The
fabric facing reduces friction with the pulley, thereby
minimising temperature build-up.
Benefits
• Substantially increased power rating.
• Highly efficient positive drive.
• Maintenance-free: no lubrication or re-tensioning needed.
• Savings in space, weight and money.

Belt Dimensions
The three principal dimensions of a
Poly Chain® GT2 belt are
pitch;
pitch length;
width.
Belt pitch is the distance in
millimetres between two adjacent
tooth centres
as measured on the pitch line of the
belt. Belt pitch length is the total
length (circumference) in millimetres
as measured along the pitch line.
The theoretical pitch line of a
Poly Chain® GT2 belt lies within
the tensile member. Gates
Poly Chain® GT2 belts are made in
8 mm and 14 mm pitches.

System Specification
The three principal dimensions of a pulley are
pitch;
number of grooves;
belt width.
On the pulley, pitch is the distance between groove centres and is measured on the pulley’s pitch circle. The pitch circle
of the pulley coincides with the pitch line of the belt engaging with it. The pulley’s pitch diameter is always greater than
its outside diameter.
Any Poly Chain® GT2 belt must be run with pulleys of the same pitch.
Poly Chain® GT2 belts can be used on existing Poly Chain® GT drives.
They operate on the same pulleys and do not require any adaptation of the system. Pulleys for Poly Chain® GT2 belts are
made in 8 mm and 14 mm pitches. Standard pulley sizes are listed on. For each Poly Chain® GT2 belt width, there is a
table listing the pulley codes, the applicable bushing style and pertinent dimensional information. Reference to the stock
bushings for Poly Chain® GT pulleys plus bore and keyway information is available to order the correct bushing.
The pulley ordering code is composed as follows:
Example: PCGT 8M 22S 12
