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 across a wide temperature range. An optional Frelon®W liner is FDA compliant, while the optional Frelon®J liner can handle the harshest of chemical contaminants. These plain bearings are all capable of rotary, linear, or oscillating movement and come in the variations of open vs closed, precision ID vs compensated ID, and the Inch Series vs ISO Metric or JIS Metric. Other Simplicity® products using the FrelonGold® liner would be Plain Bearing Pillow Blocks, Flanged Plain Bearings, Sleeve Bearings, Linear Die Set Bushings and Square Linear Bearings with Square Shafts.
Our Linear Ball Bearings consist of an outer ring, steel balls, and a polymer cage, enabling smooth and precise linear motion without limits. Compared to plain bearings, ball bearings generate slightly less friction and can operate at higher speeds.
Roller Bearing Pillow Blocks carry very heavy loads due to a larger rolling surface. A further line of Hevi-Rail Axial Bearings and Heavy Duty Linear Rails are needed for the heaviest tasks of all.
