5 CONVEYOR PULLEY SELECTION GUIDE 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 area is intended to act as the contact surface for the conveyor belt.
