Linear bearings are mechanical components that slide or roll along round or square shafts, enabling linear motion by reducing friction. PBC Linear manufactures bearings in the US, including the Simplicity® Plain Linear Bearings that feature a self-lubricating FrelonGold® PTFE liner for maintenance-free sliding in harsh environments. Our Linear Ball Bearings include a durable heat-treated outer ring, a quiet resin retainer polymer cage, and low-friction steel balls for speed. Additionally, our roller pillow blocks come with single, double, or twin sets of coated steel rollers in an open aluminum housing, designed to roll along rail-supported steel shafts for heavy-duty applications. Plain linear bearings support rotary, linear, or oscillating motion, while ball bearings avoid the 2:1 binding ratio associated with plain bearings. Both types are available in single, double, pillow block, and flange mounts, as well as Inch, ISO Metric, and JIS metric ID sizes. Plain bearings also include variants such as sleeve bearings, square bearings, and die set bearings.
