Linear Ball Bearings

Linear ball bearings are rolling-element linear bearings that use recirculating hardened steel balls instead of sliding elements to provide low-friction, straight-line motion along round shafts with only one degree of freedom. They are better suited than plain linear bearings for higher speeds, longer strokes, and overhanging cantilevered loads due to their lower coefficient of friction and because plain bearings may bind under the 2:1 rule, requiring plain bearing spacing to be at least twice the load overhang, a rule rolling-element bearings are not subject to. PBC Linear linear ball bearings feature heat-treated alloy steel shells for durability, precision steel balls for smooth travel, molded polymer resin retainers for reduced noise, and standard double seals to help keep contaminants out. However, linear ball bearings typically require more maintenance than plain bearings, including periodic lubrication and greater care to keep debris, contamination, shock, and vibration away from the rolling elements. Available in closed, open, adjustable, self-aligning, flanged, pillow block, and double-wide configurations, PBC Linear ball bearings are dimensionally interchangeable with industry standards and cover inch sizes from 1/4 in. to 2 in. ID and metric sizes from 8 mm to 50 mm ID. Static load capacities reach up to 3,500 lb. (15,900 N) and dynamic load capacities up to 1,300 lb. (6,000 N), with operating 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.
