Product Parameters
Deep groove ball bearing is a widely used rolling bearing, its main functions include:
Support rotating parts. Deep groove ball bearings support and guide the rotating movement of the shaft, reducing friction and ensuring the smooth operation of mechanical components.
Take the load. This bearing can withstand radial loads or combined loads acting simultaneously in both radial and axial directions, and is suitable for applications requiring heavy or complex loads.
High speed performance. Deep groove ball bearings are designed for high speed operation and can maintain good stability and accuracy at high speed rotation
For applications requiring high speed rotation.
Low friction and vibration. Due to its rolling friction characteristics, deep groove ball bearings have lower friction and vibration than bearings with sliding friction, which helps to reduce energy loss and improve efficiency.
Long life and reliability. High quality deep groove ball bearings with high wear-resistant materials and precision manufacturing processes have a long service life and reliability, suitable for applications requiring long-term stable operation.
In addition, the deep groove ball bearing also has the advantages of simple structure, low manufacturing cost, easy to achieve high manufacturing accuracy, the size range and form are varied, widely used in precision instruments, low noise motors, automobiles, motorcycles and general machinery and other industries.

Installation Instructions
Deep groove ball bearings can be installed on the shaft by two ends fixed, inner ring fixed and outer ring fixed in three ways.
1. Both ends are fixed
Fixed at both ends means that both ends of the deep groove ball bearing are installed on the locking sleeve at the same time, and the locking force is adjusted through the thread of the locking sleeve, so that the bearing is in a normal state of use. This installation method is simple and easy, and is suitable for the case that the length of the shaft is small and there is no obvious matching defect. However, the quality and accuracy of the lock sleeve will directly affect the service life of the bearing, and it is impossible to avoid the problem of excessive wear due to the change of the tightness of the bearing.
Second, the inner ring fixed
Inner ring fixing means that the inner ring of the deep groove ball bearing is directly installed on the shaft, and the outer ring can float. This installation method is suitable for bearing under light load, low speed, small shaft length occasions. The inner ring has a large tight fit with the shaft, which can improve the rigidity and accuracy of the bearing, prevent the bearing from sliding during operation, and thus improve the service life of the bearing.
Third, the outer ring is fixed
The outer ring fixing means that the outer ring of the deep groove ball bearing is fixed on the shaft, and the inner ring can float. This installation method is usually suitable for bearing under heavy load, high speed, large shaft length occasions. The fixing of the outer ring can ensure the stable operation of the bearing at high speed, but the combination of the bearing and the shaft is relatively loose, which is easy to lead to sliding and rotating instability. Therefore, when selecting the fixed installation method of the outer ring, it is necessary to seriously consider whether it can meet the needs of the use of bearings.
In short, the installation method of deep groove ball bearings needs to be selected according to the actual situation, and attention should be paid to understanding the structural characteristics of bearings during the installation process to avoid bearing damage or failure due to improper operation.
