Running inspection of NTN Plummer block housing with spherical roller bearing

Running inspection of NTN Plummer block housing with spherical roller bearing

Once the NTN spherical roller bearing arrangement has been assembled with NTN Plummer block housing,make sure the assembly work has been correctly achieved by following the procedure below.

1,First ,turn the NTN spherical roller bearing for Plummer block housing by hand to check that the bearing and seal are free from any irregularities.
a.Non-smooth touch:trapped dust or scratch
b,Irregular torque:abnormal interference:
c,Excessively large running torque:
  Too small bearing clearance,poor flatness of mounting seat.
2,Second,run the NTN Spherical roller bearings with plummer block housing by power, begin with no load and at lower speed.
a,Abnormal noice, dust,dent mark,or poor lubrication
b,Vibration: Greater misalignment ,or excessively large residual clearance.

3,Run the bearing under normal operating conditions to check for temperature rise on the bearing,the possible causes to abnormal 
temperature rise with bearing are as follows:
a,allowable speed has been exceeded
b,Overloading
c,too small residual clearance
d,negative clearance owing to excessive expasion or compression with the shaft
e,warped NTN plummer block housing owing to poor flatness with the mounting seat
f,poor lubrication 
g,too great tightening allowance for the contact seal, or interference with rotating components such as those around the labyrinth seal

If any irregularity is found as a result of running inspection,determine and remove the cause, then reperform the running inspection
to make sure the bearing runs normally

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
