SBR--LUU series linear sliding unit is a case unit with the standard linear bearing installed in a small and light aluminum case.The slide unit SBR--LUU series is lengthen version of standardized slide bearing housings and shaft supporters to enable smooth linear motion using slide bearings and shafts. These presented units are specifically developed in tune with the optimal class basic components altogether with sophisticated tackles and machinery to retain effectiveness and reliability.

Shaft support rail unit SBR-LUU type is a sealed, double length, metric version. The special design allows for fully supported shafts and support rail to be used for greater rigidity. These slide block bearings are most commonly found in the Asian market. 

The shaft support rail unit SBR series is characterized by small coefficient of friction and low power consumption, and achieves flexible, accurate fine movement. Also it features easy lubrication, quick, convenient maintenance and replacement. In addition, this bearing has a self-adjusting capacity in structure, which reduces accuracy of the relative accessories.


The slide units are widely used in CNC milling machines, milling machines, lathes, punching machines, grinding machines, measuring equipment, automatic equipment, high speed transfer equipment and so on.
