Four point angular contact ball bearings
1. It can withstand radial and bidirectional axial load-bearing capacity and has high bending moment resistance; 2. Compact structure, greatly saving axial space; 3. Double row or paired angular contact ball bearings can be replaced; 4. Cage made of high-strength resin or machined copper alloy; 5. Can adopt the same sealing and grease design as deep groove ball bearings; 6. NSK high-precision processing technology, excellent wear resistance and quietness.
04
Thin wall deep groove ball bearings
1. Thin-walled deep groove ball bearings make it possible to miniaturize and lighten the device; 2. The friction torque is low and the torque variation is small. The torque transmission rate is high and the operation is smooth at the same time, and can be used in high-speed operation situations; 3. Various sealing forms. There are three types of sealed ball bearings: dust cover type, non-contact sealing ring type, and contact sealing ring type.

Miniature deep groove ball bearings
1. High quietness: Optimize the internal design, improve processing accuracy, and make the bearings quieter; 2. High precision: high manufacturing precision to meet the performance requirements of humanoid robots; 3. Low torque • Long life: Use new low-torque grease to improve operating efficiency; 4. Corrosion resistance: We provide professional anti-corrosion solutions for various application scenarios of humanoid robots, covering conventional stainless steel and self-developed high-performance stainless steel bearings. They are suitable for various high-corrosion working conditions and have stable and reliable performance to ensure the long-term safe operation of humanoid robots.

Miniature angular contact ball bearings
1. High rigidity: Using a 45° contact angle structure, the axial rigidity is about 2 times higher than that of deep groove ball bearings; 2. Maintenance-free: specifications with dust-proof covers on both sides and grease sealed are available; 3. Suitable for actuator support parts. The conventional method of use is to install two sets of bearings in pairs and put them into use after adjusting the internal clearance. This is especially suitable for ball screw support scenarios. Widely used in actuator support parts such as dexterous hand joints.
