Angular contact ball bearing is a commonly used bearing in modern mechanical equipment, which can withstand both radial and axial loads, and can work at higher speeds. The higher the accuracy level, the better the operating effect of angular contact ball bearing...

Due to design, manufacturing, management, and other reasons, bearings inevitably generate vibration and sound during operation. The noise of bearings not only affects the quality of use, but also brings a lot of trouble to mechanical equipment. And bearing noise is inevitable, so many people choose to use low noise...

Lubricating oil is very important for the operation of bearings, and the quality of lubricating oil directly affects the service life of bearings, especially precision bearings have higher requirements for lubricating oil. If the quality of the lubricating oil is too poor or deteriorates, it will directly affect the working and service life of the bearings...

Deep groove ball bearings mainly bear radial loads and can also bear both radial and axial loads. When it only bears radial load, the contact angle is zero. When deep groove ball bearings have large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads...

The cage plays a role in isolating the rolling element at an equal distance in the rolling bearing and preventing it from falling, guiding and driving the rolling element to rotate. Generally speaking, the cage of thin-walled bearings with equal cross-section will not be damaged under reasonable working conditions...

When the rolling element is loaded, contact stress will be generated on the contact surface between the rolling element and the inner and outer rings. The inner and outer rings and the rolling element have relative rotational motion during operation, so the contact stress will change. When the contact stress exceeds the specified value...
