FAQ

The 'PP' suffix indicates that the linear bearing is equipped with double-sided contact seals. These seals are crucial for protecting the internal ball raceways from contaminants like dust and moisture, while also retaining the factory-applied lubricant, thus extending the service life of the bearing.

For optimal performance and lifespan, the KH08-PP should be used with a hardened and ground precision shaft with a diameter tolerance of h6 (for an 8mm nominal shaft). Using a shaft that is too soft or has an incorrect surface finish will lead to premature wear of both the shaft and the bearing.

While the KH08-PP comes pre-lubricated for life in many applications, it can be re-lubricated if necessary, especially in demanding environments. Re-lubrication should be done with a high-quality grease compatible with rolling bearings. However, due to the integrated seals, care must be taken to ensure the grease properly reaches the ball circuits.
