Consider Sealed Roller Bearings to Cut Conveyor Costs | E & MJ

At an underground mine operated by New Clydesdale Colliery in Mpumalanga, South Africa, bearings in the tail pulley of the conveyor system were failing after just several weeks due to poor sealing performance and fractured housings. A stronger solid-block spherical, roller bearing-housed unit was suggested, and the mine saw immediate improvements.

Bearing data | SKF

Bearing data. Values are valid for unmounted bearings under zero measuring load. When the position of the misalignment is not constant relative to the outer ring, additional sliding may occur in the bearing, limiting misalignment to a few tenths of a degree. To avoid detrimental effects on sealing performance, misalignment for sealed bearings
