⚙️Product features:
Space optimization: The inner ring, outer ring and the walls of the rolling elements are thinner, occupying less installation space, which helps the equipment achieve a compact design and is suitable for scenarios with strict space limitations.
Lightweight: Due to the thinner wall thickness, it is lighter than ordinary bearings of the same specification, reducing the overall burden of the equipment and helping to improve energy efficiency and mobility. It has obvious advantages in the aerospace field where weight control is emphasized.
Low friction, high rotational speed: The friction coefficient is small and the maximum rotational speed is high. When the rotational speed is high and thrust ball bearings are not suitable, it can also bear pure axial loads.
Capable of withstanding various loads: Mainly withstands radial loads. After increasing the radial clearance, it has some of the performance of angular contact ball bearings, capable of withstanding combined radial and axial loads, and can perform bidirectional axial positioning of the shaft or housing within the range of the axial clearance of the bearing.

⚙️Application scenario:
It can be used in aerospace components, medical equipment such as scanners and MRI machines, robotic automation equipment, cameras, laptops and other consumer electronic products.
⚙️Precautions:
1. Keep clean |
2. Use with caution |
3. appropriate tool |
4. Hot-loading |
5. Be careful of rust |
Dust will have a bad effect on the bearing, so keep the surrounding clean. |
Strong impact during use can easily cause scratches and indentations. |
Avoid replacing existing tools, and use appropriate tools. |
Bearings are precision parts, so hot installation is recommended. |
Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
