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 body.This area is intended to act as the contact surface for the conveyor belt.

Certain types of conveyors require fail-safe brakes for stopping. These conveyors, often used in the mining and aggregate industries, include downhill conveyors (e.g., discharge and transfer conveyors), as well as overland conveyors with downhill sections. Not having fail-safe brakes on these types of conveyors can result in catastrophic damage if power is lost.
