Sealing

The slide block is fully enclosed from all directions by a retaining plate, gap seals, an upper seal, and a lower double-sided seal. These seals ensure the rolling elements remain free from contamination even in harsh environments.

The standard double-lip seals at both ends of the slide block prevent lubricating oil or grease from escaping the system.

Preload

The RUE..-E linear recirculating roller bearing guide system offers selectable preload levels.

Optimal rigidity is achieved when preload deviations are minimal. All linear recirculating roller bearing guide systems are factory-assembled as complete sets, with components grouped and matched.

Impact of Preload on Linear Guide Systems

Higher preload yields greater rigidity.

However, preload affects friction and system service life.

Friction

The coefficient of friction depends on the C/P ratio. For unsealed systems with load ratios between C/P=4 and C/P=20:

RUE=0.002 to 0.004.

Accuracy

The accuracy grades for linear recirculating roller bearing guide systems range from G0 to G3.
