Linear Ball Bearing - Bushing

Linear Ball Bushings

Round steel shaft recirculating linear ball bearings (bushings) from PBC Linear®, crafted from high-quality heat-treated alloy steel, deliver precise, high-speed linear motion with a low coefficient of friction for smooth performance. Equipped with resin retainers to reduce noise and standard double seals for enhanced durability, they are available in closed, adjustable, open, double sized, and compact thin-wall configurations. These bearings are offered in both Imperial sizes (1/4" to 2") and Metric/JIS sizes (5 mm to 50 mm). They are interchangeable with industry standards and PBC Linear® Simplicity® bearings, allowing seamless integration as standard bearings. Outside this category, check for variants like pillow blocks and flange mounts in standard or double sizes. Unlike plain bearings, which must adhere to the 2:1 binding rule, these ball bearings handle cantilevered loads effectively.
