Linear Bearings from PBC Linear

Linear Bearings

Linear Bearings from PBC Linear® encompass three primary types: self-lubricating plain linear bearings, linear ball bearings, and roller bearing pillow blocks, all meeting industry size standards. Simplicity® Plain Linear Bearings feature a self-lubricating FrelonGold® PTFE liner, delivering maintenance-free operation in harsh environments (dirt, heat, vibration) while supporting rotary, linear, or oscillating motion. These bearings come in open or closed designs, with precision or compensated ID options, and are available in Inch, ISO Metric, or JIS Metric series. Linear Ball Bearings feature an outer ring, steel balls, and a polymer cage for smooth, precise motion without the 2:1 binding ratio of plain bearings. They include heat-treated alloy steel shells and resin retainers for quieter operation and are offered as standard bearings, pillow blocks, or flange mounts in closed, open, or adjustable forms. Roller Bearing Pillow Blocks, equipped with single, double, or twin sets of three opposing coated steel rollers in an aluminum housing, align with rail-supported steel linear shafts for heavy-duty performance.
