spherical roller bearing is used in many industrial application,it contains single-row spherical roller bearing,double-row spherical roller bearing,sealed spherical roller bearing,Rolling Mill bearing,
this kind of bearing have two rings,steel cage or brass cage,many rollers,lubrication oil.EASIER brand spherical roller bearing have many different design according the dimension and special applications,  there are one lubrication groove on the outer ring,three lubrication hole in the lubrication hole,

EASIER spherical roller bearing have some different cage design,E suffix mean pressed steel cage,this design is our owned original,(E-two window-type steel cage,flangeless inner ring and guide centred on the inner ring),spherical roller bearing 22205-22226 ,21308-21320,22308-22322 is E cage design. 

CA cage(one-piece machined brass cage of double-pronged type,retaining flanges on the inner ring and guide ring centred on the inner ring. CAC cage and CAFA is the similar with CA cage,but CAC is improved raceway geometry,CAFA is machined
steel cage.
JA suffix mean hardened steel cage,ring guided,this cage of spherical roller bearing special used in vibrating screen.Its the same
with M2 cage.
MA spherical roller bearing have machined brass cage outer ring guided, and also M2 is brass cage but no guide ring,
EASIER spherical roller bearing CC suffix :two window-type steel cages,flangeless inner and guide ring centred on the inner ring,
ECA suffix is one-piece machined brass cage,guide ring centred on the inner ring and reinforced roller complement,ECAC is the same with ECA cage, but with improved raceway geometry,ECAF is the same with ECA but ECAF is machined steel
Usually EASIER spherical roller bearing work together with the sleeve adapter and plummer block bearing housing,there are K and K30 bore design with sleeve adapter,
spherical roller bearing have different Clearance and tolerance. C1,C2,CN,C3,C4,C08(C08 reduce runout on both inner and outer ring to ISOP5 VQ424 is closer tolerance than C08,
and more suffix of spherical roller bearing as follows
W22 special reduce outside diameter tolerance for outer ring
W26 there are six lubrication holes in the inner ring,
W31 bearing inspected to special quality requirements,
W33X is different with W33,it mean lubrication groove and six holes in
the outer ring
W4 Hi point of eccentricity marked on inner ring or sleeve
W502 Combination of W22 and W33
W509 W26 + W31 + W33
W513 W26 + W33
HA1 Case hardened outer and inner rings
HA3 Case hardened inner rings (As ECB prefix)
VA405 Vibrating screen specification
VA406 As VA405 with PTFE coated bore
VE552(E) Three equally spaced threaded holes in face of outer ring for hoisting tackle,
(E) indicates appropriate lifting eyes supplied
VE553(E) As VE552 but on both side faces.
VA751 / VA759 Both printing press/coater specifications
VT143 Extreme pressure grease
W64 Solid oil filling
W77 Plugged W33 holes
2CS,2CS2,2CS5 are all double-row rubber sealed of spherical roller bearing ,its maintenance free bearing when operation. XRB bearing can supply the top quality for spherical roller bearing in the world,XRB bearing can supply outer from 52mm to 2180mm spherical roller bearing,

XRB can supply spherical roller bearing for Vibrating Screen ,bearing for Rolling Mill, Paper-making machinery,bearing for Mining and construction equipment, concrete mixer truck bearing,crusher bearing, Cranes bearing, Fluid machinery bearing,blowing machine bearing.
some small size bearing can be produced with ABEC-1,ABEC-3,ABEC-5 quality level, most of the 
spherical roller bearings we have stock, Reliable EASIER bearing can be found in XRB company.
