Maintenance and Care

• Regularly inspect the lubrication condition to ensure sufficient and clean lubricant.

• Avoid overloading or impact loads to prevent bearing damage.

• For high-speed or high-temperature applications, choose high-temperature lubricants or special material bearings.

Structure Inner ring: It is installed in cooperation with the shaft. The raceway of the inner ring comes into contact with the rolling elements, guiding the movement of the rolling elements and bearing a part of the load. Its inner diameter size corresponds to the diameter of the shaft it is matched with. Outer ring: Usually installed in the hole of the bearing seat or mechanical components. The raceway of the outer ring also contacts with the rolling elements. Together with the raceway of the inner ring, it provides a rolling path for the rolling elements. The outer diameter of the outer ring is suitable for the size of the mounting hole. Rolling elements: Generally steel balls, which are located between the raceways of the inner and outer rings. When the bearing is in operation, the steel balls roll on the raceways of the inner and outer rings to achieve relative movement and transmit the load. Since angular contact ball bearings need to bear combined loads, the size and quantity of the steel balls are usually optimized and designed according to the bearing's load-carrying capacity and performance requirements. Cage: Its function is to evenly separate the rolling elements to prevent collisions and friction between the rolling elements. At the same time, it guides the rolling elements to roll correctly in the raceways, enabling the bearing to operate smoothly and efficiently. The material and structural form of the cage will affect the performance and service life of the bearing. Common types include metal cages and plastic cages, etc. CharacteristicsCharacteristics Advantages Can bear combined loads: It can bear both radial loads and axial loads simultaneously. And according to the difference in the contact angle, the ability to bear axial loads varies. The larger the contact angle, the stronger the bearing's ability to bear axial loads, which gives it good adaptability under complex load conditions. High precision: The manufacturing precision of angular contact ball bearings is usually relatively high, which can ensure the high-precision positioning and smooth operation of rotating parts. It is suitable for occasions with high requirements for rotational accuracy, such as machine tool spindles and precision instruments. High limiting speed: Due to the relatively small friction between the rolling elements and the raceways and the reasonable structural design, angular contact ball bearings can maintain good stability and reliability during high-speed rotation and have a relatively high limiting speed, which can meet the needs of some high-speed rotating equipment.
