FAQ

V1 indicates a light preload. This provides a good balance between rigidity and low friction, suitable for general applications. Higher preloads (V2, V3) offer more rigidity but also higher friction and are used in high-precision machining applications.

Lubrication frequency depends heavily on the operating conditions (speed, load, environment). It's crucial to follow the machine manufacturer's maintenance schedule or Schaeffler's guidelines. The integrated grease nipple allows for easy relubrication.

No, it is strongly advised against. Linear guide carriages and rails are manufactured as matched pairs with extremely tight tolerances. Using an INA carriage on a non-INA rail will result in poor performance, premature wear, and potential system failure.
