2023-09-21Common problems and solutions for bearing us

Phenomenon 1: Bearing seat cracksCause:1. The bearing fit is too tight2. The inner or outer ring of the bearing is loose.3. Deformation of the bearing housing4. Poor surface processing of the bearing installation, etc.So..

2023-09-15Common problems and solutions in the use of bearings

Phenomenon 1: Metal peeling off the raceway surfaceCause:1. The bearing rolling elements and the raceway surfaces of the inner and outer rings are subject to periodic pulsating loads, resulting in periodically changing c..

2023-09-12Self-aligning Roller Bearing

1、 CharacteristicsSelf aligning roller bearings are double row non separable bearings - including solid outer rings with spherical raceways, solid inner rings, and drum shaped rollers with cages. The inner ring has cylin..

2023-09-10Detection methods and instruments for abnormal bearing noise

There are currently two ways to detect abnormal bearing noise. One is an acoustic-based noise detection method and the other is a vibration-based detection method.(1) Noise detection method:It uses a high-quality microph..

2023-09-07Causes of abnormal bearing noise

1. There are impurities in the oil2. Insufficient lubrication (oil level is too low, improper storage causes oil or grease to leak through the seal)3. The clearance of the bearing is too small or too large (manufacturers..

2023-09-04Common Failure Modes and Countermeasures of Rolling Bearings

1. Peeling off at the extreme position on one side of the channelThe spalling at the extreme position of one side of the channel is mainly manifested in the severe spalling ring at the junction of the channel and the rib..

2023-08-31Bearing failure mechanism

1. Contact fatigue failureContact fatigue failure refers to the material fatigue failure caused by the action of alternating stress on the working surface of the bearing.A common form of contact fatigue failure is contac..

2023-08-29The difference between the adapter sleeve and the withdrawal sleeve

The adaptersleeve and withdrawal sleeve are generally suitable for large bearings. The adaptersleeve is used to adapterthe round nut and adapterthe bearing, while the reverse is used for removing the sleeve.The original ..

2023-08-28Unable to start or with low amplitude

1. The motor or electrical components are damagedFirstly, check the motor. If the motor is damaged, replace it; Secondly, check the electrical components in the control circuit. If the electrical components are damaged, ..

2023-08-23Bearing overheating

In general, the normal temperature of bearings should be maintained at 35-60 ℃. If the bearing temperature is too high during use, the following reasons may exist:1. The radial clearance of the bearing is too smallDue to..
