Linear Bearings manufactured in the USA, including self-lubricating plain linear bearings, linear ball bearings, and roller bearing pillow blocks, all adhering to industry size standards.
Simplicity® Plain Linear Bearings feature a self-lubricating FrelonGold® PTFE liner for maintenance-free operation in harsh environments, resisting dirt, heat, and vibration. They support rotary, linear, or oscillating motion in open and closed designs, with options in inch, ISO Metric, or JIS Metric sizes. Simplicity bearings come in standard-size, double-size, pillow blocks, flange mounts, sleeve bearings, and die set bearings.
Linear Ball Bearings have a heat-treated outer ring for durability, a resin retainer polymer cage for quiet performance, and low-friction steel balls for enhanced speed. These ball bearings avoid the typical 2:1 binding ratio of plain bearings and come in the form of standard-sized, double-sized, pillow blocks, and flange mounts.
Roller Bearing Pillow Blocks consist of single, double, or twin sets of three opposing coated steel rollers in an open aluminum housing, rolling along rail-supported steel linear shafts for robust heavy-duty performance.
