Timing Pulleys are manufactured to extremely close specifications and are stocked in minimum plain bore, Taper Bushed and QD bushed styles depending on size and pitch . See tables for stock pulley types . Bushings are priced separately and must be added to pulley price . "F" designation in pulley type means pulley is flanged .

Archimedes Steel Wire Rope Pulleys meet the Consultant tender pulley specification of a minimum D:d ratio of 30:1. All Archimedes Pulley sheaves are manufactured from Acetal providing excellent wear resistance, mechanical strength, stiffness and good fatigue resistance under static load. All Archimedes Steel Wire Rope Pulleys rotate on sealed

Pulley/Core Diameter- The outside diameter of the cylindrical body of a conveyor pulley, without coating. Finish Diameter - The outside diameter of a coated pulley (core diameter + 2 times the coating/wrap thickness). Face Width - The length of a pulley's cylindrical body. This area is intended to act as the contact surface for the conveyor belt.
