This bearing housing combines a linear ball bearing with its mounting housing in one sealed unit, designed for linear motion along a shaft. The unit measures 70.0 mm in width and 47.5 mm in height, with a net mass of 0.3 kg. It comes pre-greased and fitted with a relubrication facility, allowing grease to be replenished without dismantling the unit, and a corrosion-resistant design variant is possible. The sealing on both sides keeps contaminants out of the raceway while retaining grease inside, which supports operation in environments where dust or debris exposure is a concern. The built-in relubrication facility allows the operator to maintain grease supply over the service life without removing the housing from its mounting, reducing downtime during maintenance. As a linear ball bearing and housing unit, KGB20-PP-AS is suited for applications requiring guided linear travel with the alignment and mounting surfaces already integrated into the housing.
