We can customize the lengh whatever you want, pls contact us before buying.Linear bearing is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Because of point contact between ball and straight axis, so the load is small. The ball is spinning with the smallest friction, it can run a high precisionand smooth motion. Flangelinear bearings can be divided into: round flange type, oval flange, guide wheel flange, guide the oval flange type, plus long round flange type.

This is the sliding unit with the aluminium case, shafts and aluminium rail for preventing deflexion. This is the complete sliding unit systemsand can be clamped simply tightening by bolt with high accuracy. The support rail unit provides maximum rigidity and stiffness to the shaft throughout the whole stroke, and ensure the performance of the unit.
