💡 What is a pillow block bearing used for in industrial shaft support and sealed ball bearing applications?

A pillow block bearing supports and locates rotating shafts while keeping dirt and contaminants out of the sealed ball bearing insert.

- Supports horizontal shafts on conveyors, gearboxes, and motor mounts for reliable shaft alignment and load handling - Sealed ball bearing insert reduces maintenance and contamination risk, suitable for dusty or wet environments - Set-screw locking and wide inner ring help steady radial loads and simplify installation on linear slide units and drives - Relubrication fitting (1/8-27 NPT) lets you extend service life without removing the housing
