💡 What is a pillow block bearing used for in conveyor and linear slide unit applications? Pillow block bearings support and align rotating shafts while providing a sealed, greaseable mounting point for industrial equipment. Quick intro: - Supports shafts and keeps alignment in conveyors, linear slide units, gear drives and power transmission systems. - Uses sealed ball bearing inserts for low-friction rotation with relubrication capability and set-screw locking for secure mounting. - Cast iron housings and contact seals with slingers offer rugged protection in heavy-duty environments where sealed ball bearing performance matters.
