This linear ball bearing enables low-friction linear motion along a shaft through recirculating ball tracks in a heavy load range design. Bore diameter is 12.0 mm, outside diameter 22.0 mm, and net mass 0.02 kg. The KS12-PP carries lip seals on both sides, protecting the raceway from contamination along its travel. The double-sided lip seals keep grease inside the bearing and block dust and debris from entering, which supports stable running under continuous linear travel. Being designed for the heavy load range, this bearing is suited for applications where higher radial loads are transmitted through linear motion, and its sealed construction reduces the need for frequent relubrication.
