Improvement of technology of spherical roller bearing

As we know,the base accuracy of inner ring of spherical roller bearing was damaged under grinding operation,Lead to higher Machining accuracy in the preceding process has been reduced,in severe cases leas scrap.just like the outer diameter of inner ring of the 22215CA/W33 spherical roller bearing,outer diameter is the base standard when griding processing,its related to the accury of the inner ring precision directly,and the width of outer diameter is a little narrow when the spherical roller bearing design,when grinding processing we usually adopted electromagnetism centerless fixture,the support point is cemented carbide,after rough grinding of the inner ring and raceway,base line was weared and reduced precision,so the coming process cannot sure about the quality of spherical roller bearing,after inspection of 22215CA/W33 we got the result ,the round average of outer diameter is 2.7μm after grinding,and the round average of inner ring and raceway increase to 10.6μm.
 
So we change the old technology ,grinding end of the ring→rough grinding outer diameter→super grinding outer diameter→rough inner diameter→rough grinding raceway→super grinding inner diameter→super grinding raceway, change new mathod grinding end of the ring→rough grinding outer diameter→grinding outer diameter→rough grinding inner diameter→rough grinding raceway→good grinding raceway→grinding outer diameter→grinding inner diameter→grinding raceway→super grinding raceway, after the new technology production,the quality of spherical roller bearing can be reach 70% of the FAG,NSK spherical roller bearing service life.

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
