The linear ball bearing (also called ball bushing or shaft guiding) consists of a polymeric cage with raceway segments made of hardened steel to guide the ball sets within the complete system. Recirculating balls provide unlimited stroke at low friction movement.

SKF linear ball bearings are available in two design ranges: the LBBR series (ISO series 1) and the LBC series (ISO series 3), interchangeable with other SKF and ISO linear ball bearings.

SKF linear ball bearings are also available in a range of units that feature lightweight, cast aluminum housings. Combined with SKF shafts and accessories, this complete offer can be used to develop simple, cost-effective linear guiding systems for a wide variety of applications.
