This linear ball bearing enables linear motion along a shaft with a bore diameter of 12.0 mm and an outside diameter of 22.0 mm, giving a net mass of 36.24 g. It is a machined-range design, sealed on all sides, which keeps contaminants out of the ball recirculation system while retaining lubricant inside the housing. The construction includes a relubrication facility, allowing grease to be replenished without dismantling the bearing from its application, which supports maintenance over extended operating periods. A corrosion-resistant version of this design is possible, making the KB12-PP-AS suitable where moisture exposure on the shaft or housing surfaces needs to be taken into account when selecting the bearing.
