Drum shell (Q235-B/Q345 seamless steel pipe), main shaft of quenched-and-tempered 45# steel, hub; rubber lagging preferred for grain service (diamond/herringbone lagging pattern).

Roller bearings and bearing housings assembled at both ends.(Q235-B/Q345: Chinese carbon-steel grades) Installation locationDrive end at the belt-conveyor head.

Driving pulley at the bucket-elevator head. Rubber lagging raises the friction coefficient and stop belt slippage, suited to humid, dusty corn workshops.

Dynamic balancing minimizes vibration at high speed and reduces belt misalignment; Compatible with belt widths 500–1200mm and corn-conveying capacities 20–400 t/h.
