PBC Linear® supplies three main types of linear bearings: Simplicity® self-lubricating plain linear bearings, linear ball bearings and roller bearing pillow blocks. The Simplicity® Plain Linear Bearings feature a self-lubricating PTFE FrelonGold® liner, ensuring maintenance-free operation in harsh environments. The Linear Ball Bearings consist of an outer ring, steel balls, and a polymer cage, enabling smooth and precise linear motion without limits. Roller Bearing Pillow Blocks carry very heavy loads due to a larger rolling surface.
