Linear Bearings

Simplicity® Self-Lubricating Plain Bearings, Roller Bearings & Ball Bearings

PBC Linear® supplies three main linear bearing categories: Simplicity® Plain Linear Bearings, Roller Bearing Pillow Blocks and Linear Ball Bearings.

The plain bearings are FrelonGold® lined, making them self-lubricating and maintenance-free. Optional liners include Frelon®J for corrosive chemical environments and Frelon®W for FDA compliance. Roller Bearing Pillow Blocks excel at handling heavy loads on uneven surfaces. For applications demanding high speed on steel shafts, our linear ball bearings are popular. 

Linear bearings come in both standard and twin (double) sizes, open or closed, inch or metric and compensated ID vs precision ID. They appear in standard form or in the form of pillow blocks, sleeve bearings, flanged bushings, square bearings, die set bearings and more (see below).
