This linear ball bearing enables linear motion along a shaft through recirculating ball tracks in a machined design. Bore diameter is 20.0 mm, outside diameter 32.0 mm, and net mass is 87.74 g. The KBS20-PP-AS design is sealed on all sides, protecting the ball tracks from contamination while retaining lubricant inside the bearing. The adjustable construction allows setting of the internal clearance to suit the fit on the shaft, which supports smooth, low-friction linear travel. A relubrication facility permits replenishment of grease during operation without dismantling the unit, extending service intervals. The design can also be supplied in a corrosion-resistant version, allowing use where standard bearing steel would otherwise be affected by moisture or aggressive environments.
