The drive pulley is the heart of the conveyor, transferring torque from the motor and gearbox to the belt by friction. Shaft sizing, weld quality and lagging selection directly determine system reliability.
We size pulley diameter and shaft from your belt tension, wrap angle and power data, and machine the gearbox end (key, diameter, length) to match your existing drive.
