Linear ball bearings are rolling-element linear bearings that use recirculating steel balls instead of sliding elements for low-friction motion along a straight-line axis with one degree of freedom. They are better suited than plain bearings for higher speeds, longer strokes, and overhanging cantilevered loads where the 2:1 binding rule can be a concern. PBC Linear linear ball bearings feature heat-treated alloy steel shells for durability, precision steel balls for smooth travel, polymer resin retainers for reduced noise, and standard double seals to help keep contaminants out. Available in closed, open, and adjustable configurations, they cover inch sizes from 1/4" to 2" ID and metric sizes from 8mm to 50mm ID. These bearings are dimensionally interchangeable with industry standards and are available as standalone cylindrical bearings, pillow blocks, flanged units, and double-sized (twin) versions for added load support. Typical load ratings reach up to 1700 lb. (7900 N) static and 850 lb. (3800 N) dynamic, with reliable operation across temperatures from -4°F to 176°F (-20°C to 80°C).

Frequently Asked Questions
When should I use linear ball bearings?
Use linear ball bearings when you need smooth, high-speed linear motion with minimal friction and good performance under overhung or cantilevered loads.
What are the main practical use differences between plain linear bearings and linear ball bearings?
Linear ball bearings differ from plain linear bearings in three key ways: (1) they resist rotation and provide more controlled, single-axis motion; (2) they handle cantilevered loads better, avoiding the ~2:1 binding limitation common in plain bearings; and (3) they support higher speeds due to rolling contact instead of sliding friction.
