Round Shaft Linear Bearing Catalog Page

Round shaft linear bearings use cylindrical shafting, typically ceramic-coated aluminum, hardened steel, or stainless steel, to support smooth, accurate linear motion in machinery. Compared with square profile rail systems, they offer a simple, versatile format that works well across a wide range of mounting and operating conditions. PBC Linear round shaft technology includes plain linear bearings, linear ball bearings, and mounted units such as pillow blocks, flange bearings, and open-shelled pillow blocks with track rollers that roll directly on the shafts. Plain linear bearings feature a FrelonGold® liner that provides self-lubricating performance, making these bearings maintenance-free and well suited for harsh environments such as dirt, heat, and vibration.
