FAQ

What does the 'PP' suffix in KH25-PP signify?

The 'PP' designation indicates that the linear bearing is equipped with double-sided contact seals (lip seals). These seals are crucial for preventing contaminants like dust and moisture from entering the bearing and for retaining the factory-filled lubricant, ensuring a long service life.

For optimal performance and bearing life, INA recommends using a shaft with a tolerance of h6. Using shafts outside this tolerance can lead to improper fit, increased friction, or premature wear.

Yes, INA KH series bearings like the KH25-PP are supplied pre-lubricated with a high-quality grease and are ready for immediate installation. For specific applications or harsh environments, refer to the manufacturer's datasheet for re-lubrication intervals and compatible greases.
