What is the reason for the abnormal noise of the eye joint bearing?

The professional name of eye joint bearing is self-lubricating rod end joint bearing, which belongs to a kind of joint bearing. The function is to connect two rods whose center lines intersect. The shaft installed in the "fish eye" can rotate a certain angle around the center line.

eye joint bearing can withstand larger loads. According to its different types and structures, it can bear radial load, axial load, or combined radial and axial loads.

Because the outer spherical surface of the inner ring is inlaid with composite materials, the bearing can produce self-lubrication during operation. It is generally used for low-speed swing motions and low-speed rotations, and can also be tilted within a certain angle range. When the support shaft and the shaft housing hole have a large misalignment, it can still work normally.

Self-lubricating eye joint bearing are used in water conservancy, professional machinery and other industries.

Two considerations:
1. If the eye joint bearing has been running for a long time and there is noise, there may be impurities entering the bearing channel; bearing related parts such as inner and outer channels, steel ball fatigue peeling and pitting; bearing lack of grease or grease deterioration.
2. If it is a new eye joint bearing, impurities may enter the bearing raceway; original defects (such as scratches, bumps, etc.) occur in related parts of the eye joint bearing, such as internal and external raceways, steel balls, and deformation of the bearing seals or dust caps Happening. However, it does not rule out changes in the accuracy of bearings or related connected parts such as deformation. It is best to turn the bearing on your hand before installing the bearing to see if its rotation is smooth and flexible.

In addition, you must pay attention to the cleanliness of the surrounding environment when installing the bearing, avoid impurities entering the bearing, avoid rough and brutal installation, and avoid directly knocking the bearing with iron or steel rod regardless of the inner and outer rings. In fact, many problems with bearings have a lot to do with whether the user's installation operation is reasonable, so if you take good care of the bearings, the bearings will run without worry.
