Why spherical roller bearing failure

When the machine operation,sometimes the spherical roller bearing failure,its very big trouble ,before the spherical roller bearing failure,it usually become very hot of the bearing,there are many cause bearing overheating,so we need to inspect the reason step by step,at the first time we need to check if the machine problem,sometimes because of its parts,for example the tolerance of the parts,the concentricity problem of the house,cover,shaft ect.,maybe its very tight between inner ring and outer ring,and also maybe the installation of the unit,let us see some reasons make the spherical roller bearing failure.as the biggest of China bearing manufacturer,XRB now introduce some information about spherical roller bearing.

1.Spherical roller bearing was broken,so it must be changed new .

2.Low lubrication or much more iron filings and impurities exist,bearing grease should not exceed the capacity 70 percent of the total volume,if the dust existed in the raceway of the spherical roller bearing,it should be change new one,low quality lubrication grease or bad bearing maintenance cause the lubrication grease failure

3.Shaft and spherical roller bearing working together too tight or loose,so we need to re grinding if too tight,if too loose,engineer need to add a bush for the spherical roller bearing.

4.Spherical roller bearing and the cover operate too tight or too loose,so we have to precess the bearing house if too tight,or add a sleeve for the cover if too loose.

5.The cover of the motor ends or cover of the bearing is defective assembly,make sure the cover of the bearing is assembly well

6.Belt too tight or poor coupling assembly,adjust the tension of the belt,correct the coupling.

7.Too little lubrication oil of spherical roller bearing,dust exist or oil ring plugging,so we need to increase the oil,change new lubrication oil,repair or change oil ring.

22216E bearing

Related bearing:SKF 22216E bearing,SKF bearing 22216E,22216CC/W33,22216 BEARING bearing size SKF spherical roller bearing 22216 dimension bearing inner diameter 80mm bearing outer diameter 140mm bearing width 33mm CXRB BEARING is 22216 china bearing manufacturer, factory,supplier and exporter, we focus on produce spherical roller bearing 22216,The design (cage)of spherical roller bearing :CAK/W33,E,E1,EAE4,CC/W33,EAS.M,C,MB/W33,BS 22216 bearing design and applincation 22216 Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions. 22216 bearings are widely used in Papermaking machinery, railway vehicle axle, rolling mill, roller gearbox, crusher,vibrating screen, printing machinery,woodworking machinery,industrial reducer,mine.and 22216 bearing are popular size that could be used in many applications. Also we deal in world famous brand bearing like SKF bearing 1.SKF bearing Group adopted ONLY High quality GCR-15 chrome steel . 2.SKF 22216 bearings are all produced according to ABEC-1,ABEC-3 strictly. 3.100% testing before shipment, 4,ISO 9001 certificate 5.highly skilled technical staff and advanced testing equipment Advantage of SKF 22216 spherical roller bearings 1.competitive price 2.many years experience cooperation with SKF,FAG,NSK,NTN,TIMKEN,KOYO,NACHI,SNR,ZKL,ZWZ,HRB etc. 3,Strong production capacity can make sure the delivery the goods as soon as possible 4.Reliable operation quality if you have demand for SKF spherical roller bearing 22216,please contact with brandbearings@gmail.com
