FAQ What is the difference between preload V1 and other preload classes?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. How often should the KWSE 20 H G3V1 be lubricated?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. Can this INA carriage be used on a guideway from a different manufacturer like THK or Hiwin?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. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
