Insert bearings, with their convenient installation and versatile application characteristics, are widely used in agricultural machinery, textile machinery, and other equipment. However, in practical use, insert bearings may produce abnormal noise. This not only affects the working environment but also may be a sign of bearing failure, which can reduce the service life of the equipment and increase maintenance costs. Therefore, identifying the causes of abnormal noise and taking corresponding solutions is crucial for ensuring the normal operation of the equipment. This article will introduce the causes and solutions of abnormal noise of insert bearings in detail.

1. Causes of Abnormal Noise of Insert Bearings

Poor lubrication: If the lubricating grease for insert bearings is not selected properly, or lubrication is not carried out in a timely manner, the friction between the internal components of the bearing will increase. This increased friction can lead to abnormal noise, and in severe cases, it may cause wear and seizure of the bearing components.

Installation deviation: When installing insert bearings, if there is a deviation in the installation position, such as improper matching between the bearing and the shaft or the housing, the bearing will be subjected to uneven force during operation. This uneven force can cause the bearing to vibrate, thereby generating abnormal noise.
