Traction and Deflection Pulleys for POLYROPE and POLYFLAT Belts
Traction and deflection pulleys (for POLYROPE, POLYFLAT) are special guide, deflection and traction pulleys. Depending on the belt type, they may be smooth or grooved, with grooves corresponding to the profile of the flat belt. The pulley design must comply with the belt type and the manufacturer's recommendations or the relevant standards and certificates.
