This linear ball bearing carries linear motion along a shaft through recirculating ball tracks housed in a cylindrical outer sleeve. The KSO12-PP has a bore diameter of 12.0 mm, an outside diameter of 22.0 mm, and a net mass of 0.014 kg. It belongs to the heavy load range design, giving it a higher load rating than standard series bearings of the same size, and is fitted with lip seals on both sides. The lip seals on both sides keep contaminants out of the ball tracks and retain lubricant, which supports stable running behavior over longer operating periods without frequent relubrication. Its heavy load range construction makes it suited for applications where the shaft carries higher radial loads relative to its diameter, while the sealed design protects the rolling elements from dust and debris ingress during linear travel.
