Linear ball bearing units

Complementary to SKF linear ball bearings, a comprehensive range of linear ball bearing units are available. They usually consist of a light-weight, aluminium housing that has been optimized to provide high strength and stiffness at the given dimensions. Due to their light weight, inertia forces caused by acceleration are kept to a minimum.

Linear bearing units, ISO series 1
Linear bearing units incorporating closed ISO series 1 bearings are available for applications where the shaft is only supported at each end and has shaft diameters ranging from 12 to 50 mm. These cost-effective bearing units are extremely compact and can accommodate loads exceeding 25.000 N. The range of these linear bearing units contain single units LUHR/LUJR (fig. 1) as well as duo units LTDR (fig. 2.), tandem units LTBR (fig. 3) and quadro units LQBR (fig. 4).

Linear bearing units, ISO series 3
In addition to the basic housing design containing a single bearing (LUC), tandem (LTC) and quadro units (LQC) are also available as cast iron flanged units (LVCR) (fig. 5). Single bearing housings and flanged units are available for shaft diameters from 8 to 80 mm, tandem and quadro housings from shaft diameter 12 to 50 mm. Except for flanged units, all housings can be ordered in open (fig. 6) or closed design (fig. 7).
