Conveyor

Bearing arrangement of snub pulleys

Conveyor belt system. An endless conveyor belt runs over various pulleys and idlers
Function   A belt conveyor system in the mining sector transports coal and spoil over long distances. The endless conveyor belt is moved by a drive system. The belt runs over numerous idlers to the discharge pulley at the end. The snub pulley deflects the returning belt in another direction. The snub pulley is not driven and is preassembled as a ready-to-fit pulley unit.

The belt conveyor system operates outdoors in a damp and dusty environment. The pulleys and bearings in the snub pulleys rotate for 16 hours a day under varying loads. Demands on the bearings are:
long calculated life
long maintenance-free life
long relubrication intervals
