This linear ball bearing provides linear motion along a shaft through recirculating ball tracks housed in a closed bearing body. The KSO16-PP has a bore diameter of 16.0 mm, an outside diameter of 26.0 mm, and a net mass of 21.39 g, matching the heavy load range design for higher radial load capacity within this bearing series. Lip seals fitted on both sides keep contaminants out of the ball tracks and retain lubricant inside the bearing, which supports stable operation over longer service intervals. The closed design of the KSO16-PP requires a shaft with matching tolerance to maintain smooth linear travel, and the heavy load range construction makes it suitable where radial forces on the linear motion axis are higher than in standard-range types.
