NTN Sealed spherical roller bearings

NTN Sealed spherical roller bearings
 

Sealed spherical roller bearings is new design of self aligning roller bearings,in some severe dust pollution environment applications,just like hoist conveyor,Dust entering have  Crucial influence for the service life of the sealed spherical roller bearings,so the bearing housing usually designed triple sealing and the gease internal of the bearing are usually polluted by the dust,under this situation,NTN Research and design sealed spherical roller bearings.reduce the length of the rollers,reduce the cross of the inner and outer rings,

 

NTN Sealed spherical roller bearing adopt Standard ISO dimensions,install contact sealing on 

the both side of the spherical roller bearings,and injected non-lubricated grease in advance, meanwhile,make the lubrication groove and holes,so the bearing can be lubricated if the application needed.but the sealing installation have a little bigger space.so NTN redesign the internal structure, for make sure the same load capacity,NTN design more rollers can be installed,these bearing can interchange each other with the open spherical roller bearings,it can operating reliable under the situation -25--+120 degree temperature,of course the dimension is not changeable.

 

NTN can produce sealed spherical roller bearing WA22212BLLS-WA22232BLLS series, tapered bore and cylindrical bore can be avaiable,these bearing usually be installed in NTN pillow block housing.XRB as the China bearing manufacturer,also produce and distributor NTN sealed spherical roller bearing.
