2311 EC 55*120*43mm Cyl Roller Bearing , Single Row Bearings With Low Noise

Description,

There are many types of cylindrical roller bearings, which are distinguished by structure, including N, NF, NJ, NU, NUP, NCL, RN and RNU types. According to the load capacity, there are ordinary and reinforced cylindrical roller bearings. The external dimensions of reinforced cylindrical roller bearings are the same as those of ordinary types, but the diameter, length, and number of rollers have increased, so the load bearing capacity has increased.

According to the number of cylindrical roller rows, there are single-row and multi-row cylindrical roller bearings. Cylindrical roller bearings are divided into four-row cylindrical rollers and double-row cylindrical rollers. They have high radial bearing capacity but cannot support axial forces. They have small radial dimensions and high limiting speeds. They can be installed separately because the inner ring has no ribs Inner and outer ring assemblies (with full set of rollers and cages). ---- This type of bearing has the advantages of large radial load capacity, high rotation accuracy, and convenient installation and disassembly for various cold and hot rolling mills with frequent roll replacement. Suitable for work rolls or backup rolls on various hot and cold rolling mills, bloom mills and other rolling mills

How to check if a cylindrical roller bearing is malfunctioning

When the performance index of the cylindrical roller bearing is lower than the requirements for use and cannot work normally, the cylindrical roller bearing fails or even fails. Once the cylindrical roller bearing fails, the machine and equipment will stop and appear. Various abnormal phenomena such as loss of function, so it is necessary to find out the cause in the short term and take corresponding measures.

1. Rolling sound of cylindrical roller bearing

Cylindrical roller bearing noise is caused by the cylindrical roller bearing itself, that is,

the inherent noise of the cylindrical roller bearing; the other is the noise generated

after the cylindrical roller bearing is installed, which has nothing to do with the noise

of the cylindrical roller bearing itself. Some problems can be analyzed by listening to

the sound.

a) Noise related to the manufacture of cylindrical roller bearings: This includes cage noise and tremolo. The cage noise mainly occurs in ball cylindrical roller bearings and tapered roller cylindrical roller bearings. The vibration of the frame and the collision between the cage and the rolling body will produce a sound, which sounds periodic. Tremolo is a sound with a certain frequency, which is caused by the vibration caused by the large waviness on the raceway surface.

b) Intrinsic noise: rolling track sound: The rolling track sound is caused by the elastic

characteristics of the rolling elements in contact with the rolling tracks. When the cylindrical

roller bearing rotates, the rolling elements roll on the rolling tracks and are continuous and

smooth Sound; abnormal rolling friction sounds can produce uncomfortable metal friction

abnormal sounds such as "creak, creak", which will not be emitted when lubrication is good.

Therefore, it is not a problem in general, and you only need to pay attention after the noise increases.

c) Noise caused by improper use: It exists for all kinds of cylindrical roller bearings. When the surface

of the cylindrical roller bearing raceway or the surface of the rolling body is hit, pitted, or rusted, a

certain period of noise and vibration will occur. When the cylindrical roller bearing is invaded by dust

during operation, dirt noise will be generated. This noise is non-periodic and also accompanied by

vibration. The sound level is not constant and sometimes no.
