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.
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.
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
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.
