This 32-tooth HTD 8M round-tooth taper-bush timing pulley uses the metric High Torque Drive (HTD) tooth profile and is designed for heavy-load, high-precision, high-belt-speed industrial transmission. Compared with traditional trapezoidal teeth, the round tooth profile withstands greater shear stress, making it an efficient power transmission solution to replace heavy chains and gears.
