We provide a complete range of linear ball bearing units. Linear ball bearing units, which include a bearing and housing, are available as single, tandem or quadro units. The housings are made of light-weight cast aluminium that has been optimized to provide high strength and stiffness. Due to their light weight, acceleration and inertia forces are kept to a minimum. Linear bearing units are available for shaft diameters ranging from 8 to 80 mm and allow to create linear guidance systems that are really cost-effective, usually in combination with linear ball bushings.  Single and tandem units in our range include standard or flanged linear ball bushings with open, closed, or shielded designs and with or without adjustable clearance.
