FAQ

C2 denotes a high preload. This eliminates clearance between the balls and the raceway, resulting in higher rigidity and accuracy, which is crucial for applications like machine tools. Lower classes (C0, C1) have less to no preload, offering lower friction but less rigidity.

No, it must be used with a corresponding Rexroth size 20 profile rail. The raceway geometry and manufacturing tolerances are specific to Rexroth to ensure the specified precision and load ratings. Using it on a non-Rexroth rail will lead to poor performance and premature failure.

This runner block comes pre-lubricated from the factory for initial commissioning and corrosion protection. However, it is essential to connect it to a central lubrication system or follow the recommended manual re-lubrication schedule to ensure a long operational life.
