What is spherical roller bearing

 

spherical roller bearing also named self-aligning roller bearing, it consist of outer ring (one spherical raceway),inner ring(two raceway),spherical rollers and cage with pressed steel & brass or nylon metarial,some special design also have the guide ring,all of the XRB Bearing have their optimized design according different cage,so it can be the longer service life and reliable quality .we can supply many different cage disign:

 

Brass cage: CA/W33 CAE4 EAS.M E1A.M  M BD1 W33M MB BS

Steel cage: E E1 EAE4 CJ EJ CDE4 

As one of China bearing manufacturer,XRB can produce all types of roller bearings,which of the bearings with good quality and competitive price on the market,now we talk about one of our roller bearings--spherical roller bearing.

 

all of XRB bearing are adopted advanced equipment and Japan standard, so its Service life can reach 70% of World Top bearing,we can supply the black chamfer ,black lubrication groove,our normal design of outer ring will have three Lubrication hole,and also special design of four hole or six hole in outer ring and three hole in the inner ring,and more special application like high temperature(S11),we also have the solution for our customers.

 

we indicate some of our bearing suffix as follows:

 

HA3  Case-hardened precessing of inner ring

K    Tapered bore, taper 1:12

K30  Tapered bore, taper 1:30

P5   Dimensional and running accuracy to ISO tolerance class 5

P6   Dimensional and running accuracy to ISO tolerance class 6

W    Without annular groove and lubrication holes in outer ring

W20  With three lubrication holes in outer ring

W26  Six lubrication holes in the inner ring

W33  Annular groove and three lubrication holes in outer ring
