Suffix of sealed spherical roller bearings

Suffix of sealed spherical roller bearings

 

Sealed spherical roller bearings have the same internal design with open spherical roller bearings, we design the suffix of sealed spherical roller bearings,for easier to distinguish the sealed and open bearings,expect the width of BS2-22 and BS2-23 series sealed bearing are bigger than 222 and 223 series bearings,the others are all the same designation dimension.

 

China bearing manufacturer ,XRB Sealed spherical roller bearing normally with cylindrical bore,but most of BS2-22 series bearing can supply design with tapered bore,according to special demand of customers,once the quatity is OK,each of sealed spherical roller bearings can be with tapered bore,now we show the suffix of sealed spherical roller bearings as follows:

 

C2 Radial clearance small than normal clearance
 

C3 Radial clearance larger than normal clearance
 

C4 Radial clearance larger than C3
 

C5 Radial clearance larger than C4
 

2CS Hydrogenated nitrile rubber contact sealing with steel rib on double sides,lubrication 

on outer ring and three holes  
 

2CS2 Viton (FPM)contact sealing with steel rib on double sides,lubrication on outer ring and 

three holes,inject Polyurea high temperuture grease
 

2CS5 Hydrogenated nitrile rubber contact sealing with steel rib on double sides,the others 

is the same with 2CS2
 

K:tapered bore，Taper 1:12
 

K30：tapered bore,taper:1:30
 

VT143 inject extreme pressure grease
