KH series linear ball bearings are recirculating ball bearing units with a small radial section height. They have a drawn and hardened outer cup and a plastic cage forming a closed linear bearing ready to assemble. Their closed design makes them suitable for use on shafts. These bearings offer high precision and rigidity which is why they are commonly used in precision machinery.
