Linear Bearings from PBC Linear

Linear Bearings

Linear Bearings from PBC Linear® include self-lubricating Simplicity® Plain Linear Bearings, Linear Ball Bearings, and Roller Bearing Pillow Blocks. Simplicity® bearings feature FrelonGold® PTFE liners for maintenance-free operation in harsh conditions (dirt, heat, vibration), supporting rotary, linear, or oscillating motion in open/closed designs, with precision or compensated IDs in inch, ISO Metric, or JIS sizes. They are available as single sized, double sized, pillow blocks, flange mounts, sleeve bearings, square bearings, or die set bearings. Linear Ball Bearings feature a heat-treated outer ring for durability, low-friction steel balls for high speed, and a resin retainer polymer cage for quiet operation. They avoid the 2:1 rule of plain-bearing binding and are available in single sized, double sized, pillow block, or flange mount configurations. Roller Bearing Pillow Blocks, with single, double, or twin sets of three coated steel rollers in an open aluminum housing, roll along rail-supported steel shafts for robust, heavy-duty performance. All are size-interchangeable with industry standards.

Linear Bearings from PBC Linear® encompass three primary types: self-lubricating plain linear bearings, linear ball bearings, and roller bearing pillow blocks, all adhering to industry size standards. 1) Simplicity® Plain Linear Bearings feature a self-lubricating FrelonGold® PTFE liner for maintenance-free operation in harsh conditions—such as dirt, heat, and vibration—supporting rotary, linear, or oscillating motion in both open and closed designs, with precision or compensated IDs available in inch, ISO Metric, or JIS metric sizes. Variants include standard sized, double sized, pillow blocks, flange mounts, sleeve bearings and die set bearings. 2) Linear Ball Bearings have a heat-treated outer ring for durability, low-friction steel balls for enhanced speed, and a resin retainer polymer cage for quiet operation, avoiding the 2:1 binding ratio common in plain bearings. Similar to plain linear bearings, linear ball bearing options include standard, double-sized, pillow blocks, and flange mounts. 3) Roller Bearing Pillow Blocks feature single, double, or twin sets of three opposing coated steel rollers attached to an open aluminum housing that rolls along rail-supported steel linear shafts, ensuring robust performance for heavy-duty applications.
