This linear ball bearing enables low-friction linear motion along a shaft, using recirculating ball tracks within a machined open-design housing. Bore diameter is 12.0 mm, outside diameter 22.0 mm, and net mass is 28.99 g. The construction allows execution in corrosion-resistant materials. The bearing is sealed on all sides, protecting the internal ball tracks from contamination while retaining lubricant within the unit. The open design permits mounting directly on a shaft without a closed housing, suiting applications where axial travel along a supported shaft is required and where sealing against dust or moisture ingress is needed.
