Several common bearing problems and solutions

Bearings are an important part of machinery and equipment. They can be seen in factories, cities, and rural areas. Bearings may encounter various problems during use. Do you know the reasons for these problems?

The reason for the large vibration is: poor equipment, countermeasures: correct the right angle of the shaft and the shoulder of the shell, and the direct view point of the side of the pad. Outer surface deformation, countermeasures: focus on bearing replacement operations. Foreign matter intrusion, countermeasures: replace bearings, remove all parts, improve sealing equipment, etc. Stripping, countermeasures: replace the bearing.

Regulation noise, the cause: deformation of the surface, countermeasures: replace the bearing, pay attention to its use. Because of the indentation, rust or scratches on the rolling surface caused by foreign objects, countermeasures: replace the bearing, remove the relevant parts, improve the sealing equipment, and use clean lubricants. Raceway surface peeling, countermeasure: replace the bearing.

Irregular noise, the cause: foreign matter intrusion, countermeasures: study to replace bearings, remove related parts, improve sealing equipment, use clean lubricants. The clearance is too large, countermeasures: study cooperation and bearing clearance, and correct the preload. Spherical injury, peeling, countermeasures: replace the bearing.

Large metal noise, the cause: lack or unsuitability of lubricant, countermeasures: make up the lubricant, choose the appropriate lubricant. Abnormal load, countermeasures: corrective cooperation, study bearing clearance, adjustment and load, correct shell bearing shoulder orientation. Poor equipment, countermeasures: processing accuracy of shafts and housings, improving equipment accuracy and equipment methods. Rotating parts have touches, countermeasures: Correct the touch of curved road seals.

Abnormal temperature rise, the cause: poor equipment, countermeasures: improve the machining accuracy of the shaft and housing, equipment accuracy, equipment methods. Excessive lubricant, countermeasures: reduce lubricant, excessive use, select harder grease. Abnormal load, countermeasures: correction cooperation, study bearing clearance, adjust preload, and correct the shoulder orientation of the shell. Lubricant is lacking or unsuitable, countermeasures: make up the lubricant, select the appropriate lubricant. The creep of the cooperation surface and the conflict of the sealing equipment are too large. Countermeasures: replace the bearing, discuss the cooperation, correct the shaft and the housing, and change the sealing method.
