Damage Repair Countermeasures And Maintenance Methods Of Fag Self-Aligning Roller Bearing

Fag Self-Aligning Roller Bearing

1. Bearing cleaning

When disassembling the lower self-aligning roller bearing for maintenance, first record the appearance of fag bearing, confirm the residual amount of lubricant, and wash the bearing after sampling the lubricant for inspection. As a cleaning agent, gasoline and kerosene are commonly used.

The cleaning of the removed bearing is divided into coarse Fag  Self-Aligning Roller Bearing cleaning and fine cleaning. Put the metal mesh pad bottom in the container respectively, so that the fag bearing does not directly contact the dirt of the container.

During rough cleaning, if the bearing rotates with dirt, it will damage the rolling surface of the bearing, which should be paid attention to. In the coarse cleaning oil, use a brush to remove the grease and adhesion. After it is roughly clean, turn to fine cleaning.

Fine cleaning is to carefully clean Fag Self-Aligning Roller Bearing the self-aligning roller bearing while rotating in the cleaning oil. In addition, the cleaning oil should always be kept clean.

2. Maintenance and judgment of bearing

In order to judge whether the disassembled self-aligning roller bearing can be reused, it is Fag Self-Aligning Roller Bearing necessary to check after the bearing is cleaned, and carefully check the state of raceway surface, rolling surface and mating surface, the wear of cage,

the increase of clearance of fag bearing and whether there are damages and abnormalities related to the decline of dimensional accuracy. For non separable small ball bearing, support the inner ring horizontally with one hand and rotate the outer ring to confirm whether it is smooth.

For split bearings such as self-aligning roller bearings, the raceway surfaces of rolling elements and Fag Self-Aligning Roller Bearing outer rings can be inspected respectively.

Damage Repair Countermeasures And Maintenance Methods Of Fag Self-Aligning Roller Bearing

Since large bearings cannot be rotated by hand,

pay attention to the appearance of rolling elements, raceways, cages, retaining surfaces, etc. the higher Fag Self-Aligning Roller Bearing the importance of fag bearings, the more careful the inspection is.

The judgment of whether the bearing can be reused is determined by considering the damage degree, mechanical performance, importance, operating conditions and the period until the next maintenance. However, if there are the following defects, they can no longer be used, and the self-aligning roller bearing must be replaced with a new one:

(a) Cracks or notches on any one of the inner ring, outer ring, rolling Fag Self-Aligning Roller Bearing element and cage;

(b) Any one of the ferrule and rolling element is broken;

(c) There is significant jamming on the raceway surface, retaining edge and rolling body;

(d) Significant wear of cage or significant relaxation of rivets;

(e) There is rust and damage on the raceway surface and rolling element;

(f) There are serious indentation and indentation on the raceway surface and rolling element;

(g) There is obvious creep on the inner diameter surface of the inner ring or the outer diameter surface of the outer ring;

(h) Obvious discoloration caused by heat;

(i) The bearing, sealing ring or dust cover sealed with grease is obviously damaged.

If there is no wrong selection and can be used correctly, it can be used for a long time before the end of the service life of fag bearing. In this case, the damage state of self-aligning roller bearing is peeling. On the other hand, there is an early injury that can not stand the use of accidental early injury as the cause of the early injury.

The specific reasons include insufficient consideration of use and lubrication, foreign matter intrusion, large bearing assembly error and shaft deflection, Fag Self-Aligning Roller Bearing insufficient research on shaft and bearing housing, etc.

it can be said that these reasons overlap with each other. Therefore, we suggest that you choose the size of the bearing according to the service life formula of fag bearing, and on the basis of fully understanding the machine used by the self-aligning roller bearing, the service conditions and the structure around the bearing,

if you can understand the situation before and after the accident, and then investigate the damage of the bearing and various reasons, you Fag Self-Aligning Roller Bearing can prevent the recurrence of similar accidents.
