PBC Linear has combined Frelon material with precision bearing technology to create Simplicity linear plain bearings. Simplicity self lubricating plain bearings can move in linear, oscillating, rotary, or any combination of motions at speeds exceeding 4 m/s (165 in/s). Designed to handle loads 20 times greater than linear ball bearings, they will not catastrophically fail.
Pacific Bearing manufactures linear guide systems and components for drawers, guard door slides, packaging applications, and semi-conductor wafer handling, among other applications. The company, founded in 1983, is headquartered in Rockford, IL.
