STD Taper Lock Timing Pulleys
STD Taper Lock timing pulleys are the basic type of pulleys for belts in the STDSuper Torque Drive
The involute shape of the STD profile allows optimal tooth engagement with the pulley. As a result, it provides precise and quiet operation even at high belt speeds. profile. They are made of steel or gray cast iron.
The pulleys are mounted on shafts using the Taper Lock bushes, thanks to which there is not only a fixing on the shaft with a keyway, but also an axial locking against displacement.
Pulleys Fields of Use
The STDSuper Torque Drive
The involute shape of the STD profile allows optimal tooth engagement with the pulley. As a result, it provides precise and quiet operation even at high belt speeds. Taper timing pulleys are designed for all types of STDSuper Torque Drive
