The Failure Causes of Four Row Cylindrical Roller Bearings in Use are Analyzed

• During the operation of the mechanism, the part where the rod end joint bearing is installed is allowed to have a certain temperature. When touching the shell of the mechanism by hand, it should be normal not to feel hot. On the contrary, it indicates that the temperature of SKF Bearing is too high.The Failure Causes of Four Row Cylindrical Roller Bearings in Use are Analyzed
• SKF Bearing temperature is too high due to: the quality of lubricating oil is unqualified or deteriorated, and the viscosity of lubricating oil is too high; The mechanism assembly is too tight (insufficient gap); The assembly of rod end joint bearing is too tight; The bearing race rotates on the shaft or in the shell; Excessive load; Broken bearing cage or body, etc.
• The SKF Bearing is allowed to make slight running noise in the office. If the noise is too large or there is abnormal noise or impact sound, it indicates that the rod end joint bearing is faulty.The Failure Causes of Four Row Cylindrical Roller Bearings in Use are Analyzed

1. Maintenance, overhaul and abnormal handling of bearings

In order to maintain the original performance of the rod end joint bearing in good condition for as long as possible, it is necessary to maintain and repair in order to prevent accidents, ensure the reliability of operation and improve the productivity and economy. Maintain the operation standard of corresponding mechanical operation conditions and carry out it regularly. The contents include monitoring the operation status, replenishing or changing lubricants, and regular disassembly inspection.

As the maintenance items in operation, there are SKF Bearing rotation sound, vibration, temperature, lubricant state and so on.

2. Bearing damage and Countermeasures

Generally, if the rod end joint bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidental and premature damage, which is not resistant to use. This early damage, as opposed to fatigue life, limits the use of quality known as failure or accident. Most of them are caused by careless installation, use and lubrication, foreign matters invading from the outside, and insufficient research on the thermal effects of shafts and shells.The Failure Causes of Four Row Cylindrical Roller Bearings in Use are Analyzed
