Linear Ball Bearings

For High Speed, Cantilevered Loads

Linear ball bearings are linear bearings that, unlike plan sliding variants, use recirculating ball elements to provide low-friction linear motion along precision shafts and are best suited for higher speeds and cantilevered loads that plain linear bearings cannot support due to the 2:1 binding ratio. Unlike plain linear bearings, which rely on sliding contact and excel in harsh, contaminated environments, linear ball bearings use rolling contact to achieve smoother motion, higher speeds, and improved positional accuracy in clean operating conditions.

They consist of hardened steel outer shells and recirculating ball circuits that roll within the bore’s inner diameter along round shafts, minimizing friction while maintaining load support from multiple directions. This rolling element design enables consistent performance in automation, packaging, and precision motion systems where speed, repeatability, and low resistance are critical.

These industrial standard bearings are available in inch, ISO metric, and JIS metric sizes, in steel or stainless-steel constructions, with load capacities up to 166,000 lb (740 kN) and maximum speeds up to 8 m/s (315 in/s). Optional seals—nitrile, urethane, or Viton® for inside diameters ≥ ½″ (20 mm)—are available, and open-shell designs are well suited for use on rail-supported shafts
