6902 2RS Chrome Steel Single Row Thin Wall Deep Groove Ball Bearing
⚙️Structural composition:
The basic structure of 6902 is simple, consisting of an inner ring, an outer ring, steel balls and a cage. It can bear radial loads. When the radial clearance is increased, it can also bear combined radial and axial loads, and even pure axial loads under specific conditions. It can perform bidirectional axial positioning of the shaft or housing within the axial clearance range of the bearing, and has a slight self-aligning ability of 2' to 10'.

⚙️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.

⚙️Typical applications:
Due to its thin wall and high-speed characteristics, it is suitable for scenarios with limited space and high-speed requirements. It is commonly used in various medical equipment such as diagnostic and monitoring devices, and is also applied in aerospace equipment, industrial robots, rotary encoders, stepper motors, laser engraving machines, and other devices.
⚙️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. |
