This bearing housing combines a linear ball bearing with an integrated housing block, designed for guided linear motion along a shaft. It measures 52.0 mm in width and 35.8 mm in height, with a net mass of 0.1 kg. The unit is sealed on both sides and greased at the factory, with a relubrication facility built into the housing to allow grease replenishment during service without dismantling the unit. The sealing arrangement keeps out dust and moisture while retaining the grease fill, making the unit suitable for continuous linear travel where contamination control matters. A corrosion-resistant design variant is possible for the KGB12-PP-AS, extending its use to environments where standard bearing steel would be exposed to moisture or aggressive media. The housing block simplifies mounting and alignment along the shaft axis, since the bearing and housing form one dimensionally fixed assembly.
