Pitch in inches
PITCH : XL- L- H- XH
The classic trapezoidal profile is the original tooth design of timing belts. This profile can be used in transport and power transmission applications. The width of the teeth ensures good load carrying capacity on the sliding surface. This profile is suitable for less demanding applications.
L - 9.525 mm pitch
XL - 5.08 mm pitch
H - 12.7 mm pitch
XH - 22.225 mm pitch
T profile
PITCH: T5- T10- T20
This trapezoidal profile, here in metric pitch, is the original design of timing belts.
It is usually used for transport and power transmission applications. Compared with the inch pitch profile, the tooth is higher, which reduces the risk of tooth skipping, but the backlash is slightly greater.
This profile is suitable for less demanding applications.
T5 - 5mm
T10 - 10mm
T20 - 20mm
AT profile
PITCH: AT5- AT10- AT20
This profile has been developed to provide greater load capacity and reduced backlash. The stiffer teeth make these belts ideal for linear positioning and motion control, but may require larger diameter pulleys.

AT10
AT20
STD Profile
PITCH:STD5- STD8
This profile ensures better load distribution on the tooth, reduced backlash, less wear and less noise.
It is a good profile for linear and rotary positioning as well as high-speed power transmission.
STD5
STD8
HTD Profile
PITCH: HTD5- HTD8- HTD14
This rounded profile was originally developed for power transmission. It is excellent for linear and rotary positioning as well as power transmission.
The higher teeth reduce the risk of teeth jumping compared with trapezoidal profiles, but this profile is noisier and more sensitive to wear.
