The BLH bearing parts series S689 is a standard single row deep groove ball bearing, which is an inseparable radial ball bearing. The inner and outer grooves are relatively deep, and the shoulder guard usually does not have a ball loading gap. Standard retainers include nylon PA66 retainers, solid brass retainers, stamped steel plate or copper plate retainers. Bearings have open or sealed designs. Due to the standardization of manufacturing processes, both the inner and outer rings of open bearings are machined with grooves that can accommodate sealing rings and dust covers. Single row deep groove ball bearings have a wide range of applications, reliable operation, easy maintenance, and are very economical. Due to their significant advantages, they are the most widely used rolling bearings worldwide. Therefore, BLH Bearing Factory produces many different sizes and designs of deep groove ball bearings.
C-series deep groove ball bearing S698
The structure of C-series deep groove ball bearings is the same as that of single row standard deep groove ball bearings, but has been optimized in the following aspects:
1. Run quieter
2. Better sealing effect
3. Lower friction torque
BLH has analyzed the root causes of noise in deep groove ball bearings using the most advanced technological methods. Based on the analysis results, the measures taken are as follows:
1. Improved the surface of the raceway
2. Improved the quality of steel balls
3. Optimized the tightness
4. Improved machining accuracy
5. The deep groove ball bearings use a new type of steel riveted cage,
This makes the noise of C-series bearings lower than that of standard deep groove ball bearings.
The sealing performance of bearings not only affects the rated life of rolling bearings, but also affects the performance of bearing use. Therefore, sealing must not only effectively protect the operating system from pollution, moisture ingress, and loss of lubricating grease, but also ensure that the total friction torque and heat generation of the bearing remain at a low level under the sealing effect.
The new dust cover, non-contact seal, and contact seal of the C-series deep groove ball bearing S698 (with suffixes Z, BRS, HRS, ELS) demonstrate BLH's success in overcoming technical difficulties.
C-series deep groove ball bearing S698 is suitable for industries:
Single row deep groove ball bearings are particularly suitable for applications such as motors, electrical machinery, washing machines, ventilation equipment, and power tools. However, in order to further improve the efficiency of motors, equipment, and tools, it is necessary to reduce the power loss generated in the bearing arrangement. The above noise reduction measures also reduce friction by approximately 35%.
