Tooth
Pitch Selection
Imperial Pitch
Belts - XL, L, H, XH
Pitch
Details
These classic trapezoidal tooth pitches are the
original timing belt tooth design. This tooth pitch is commonly used for
conveying applications. The tooth profile is fairly low and has a large surface
area at the tip of the tooth providing good support on sliding conveyor
surfaces.
----------------------------------------------------------------------------------------------------
T Pitch Belts - T2.5, T5,
T10, T20
Pitch
Details
These metric trapezoidal pitches are similar to
imperial pitches, commonly used for conveying applications, yet have a slightly
deeper tooth engagement than imperial profiles. The tooth meshing is more
reliable. However, backlash can be slightly greater.
----------------------------------------------------------------------------------------------------
AT Pitch Belts - AT5, AT10,
AT20
Pitch
Details
Developed to enable higher load carrying
capacity combined with low backlash. Stronger and stiffer tooth makes these
belts ideal for linear positioning and motion control, but may require larger
pulley diameters
----------------------------------------------------------------------------------------------------
STD
Pitch Belts - STD5, STD8
Pitch
Details
Provides superior load distribution, low
backlash, and reduced wear and noise characteristics. Excellent profile for
linear and power transmission applications
----------------------------------------------------------------------------------------------------
HTD®
Pitch Belts - HTD5, HTD8, HTD14
Pitch
Details
Rounded tooth
pitch is similar to STD. Excellent profile for rotary linear positioning and
power transmission applications. Has deeper tooth engagement. HTD® may exhibit
slight increases in noise and wear.
----------------------------------------------------------------------------------------------------
GMT3™
Pitch Belts - GMT3™
Pitch
Details
This 3 mm tooth geometry is designed to run
on HTD®, GT and RPP pulley profiles. It is ideal
for conveying applications
involving small diameter pulleys. The deep tooth engagement
provides good
torque transfer from pulley to belt. The flat top provides a good
running
surface for slider beds.
