precision thin-wall bearing，four-point contact ball bearing

I. Precision / Stainless Steel Thin-Wall Bearings These bearings feature ultra-thin walls lightweight design and high compatibility. Their wall thickness is precisely controlled within a very narrow range significantly saving internal installation space in robot joints without adding extra load to the robot limbs. The stainless steel thin-wall bearings are made of high-grade stainless steel offering excellent corrosion resistance and low-temperature tolerance making them suitable for complex operating environments of service robots and special humanoid robots. Meanwhile the low-friction design effectively reduces joint energy consumption and improves robot endurance. They are core matching bearings for delicate components such as robot fingers and elbow joints. II. Four-Point Contact Ball Bearings These bearings are specially designed to meet the requirements of bidirectional load carrying high rotational speed and low backlash in robot joints. A single bearing can withstand both bidirectional axial loads and radial loads simultaneously with a compact structure and low rotational resistance. In large-swing-angle high-load joints such as robot shoulder joints and hip joints they achieve millisecond-level motion response. The zero-backlash characteristic ensures precise positioning of robot movements and avoids offset errors. In addition the high-wear-resistance design greatly extends the trouble-free service life of the joints.
