Purpose and direction of preloading for rolling bearings

2025-09-16

Pre tightening of rolling bearings refers to the initial pressure and pre deformation generated between the rolling elements and the inner and outer rings of the bearing during installation, in order to maintain the inner and outer rings of the bearing in a compressed state and enable the bearing to operate in a negative clearance state under working load...

Characteristics and causes of bearing grinding cracks, as well as preventive measures

2025-09-16

Grinding processing is a common method of metal cutting in the mechanical manufacturing industry and is widely used in the bearing processing industry. Bearing parts that have been heat-treated and quenched may exhibit mesh like cracks or small cracks arranged in a regular pattern during the grinding process, known as grinding cracks. These cracks not only affect the appearance of the bearing part......

The influence of pre tightening and rotational speed on bearing stiffness and temperature

2025-09-16

As an important component of mechanical rotation, the stiffness and temperature of bearings directly affect their efficiency in mechanical operation. In order to provide the rotational accuracy of bearings, increase the rigidity of bearing devices, and reduce shaft vibration during machine operation...

Damage status and cause measures of bearings

2025-09-16

When the bearing is subjected to load rotation again, the raceway surfaces or rolling surfaces of the inner and outer rings exhibit a fish scale peeling phenomenon due to rolling fatigue. Reason: Excessive load...
