Imperial Pitch Belts - XL, L, H, XH

Pitch Details 

Imperial Pitch 

Application Uses
Conveying 

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 

T Pitch

Application Uses
Conveying 

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 

AT Pitch

Application Uses 
  Linear Positioning 
Motion Control

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 

STD Pitch

Application Uses
Linear Positioning 
Power Transmission 

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 

HTD Pitch

Application Uses
Linear Positioning 
Power Transmission 

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.
