Thin Wall Deep Groove Ball Bearing – Open Four Point Contact Ball Bearing KA Series
Characteristics
Thin walled deep groove ball bearings with equal cross-section usually have good high-speed performance and can maintain stable operation during high-speed rotation. Their design makes them a lightweight, high-performance, and space saving bearing solution, particularly suitable for fields that require high precision and lightweight design.
Application
Thin walled deep groove ball bearings are suitable for various application fields, including aerospace, medical equipment, robotics technology, semiconductor manufacturing equipment, measuring instruments, communication equipment, and industrial machinery.
Installation precautions
The service life and installation of thin-walled deep groove ball bearings with equal cross-section are closely related, and the following matters should be noted.
1. Bearing installation should be carried out in a dust-free and clean room;
2. Before installing the bearing, it should be cleaned thoroughly. When cleaning, the inner ring slope should face upwards, and the hand should feel flexible without any stagnation. After drying, the specified amount of grease should be added. If it is oil mist lubrication, a small amount of oil mist should be added;
3. Special tools should be used for bearing installation, and the force should be evenly distributed. Knocking is strictly prohibited;
4. The storage of bearings should be clean, ventilated, free of corrosive gases, with a relative humidity not exceeding 65%. Long term storage should be regularly rust proofed.
