2.Description
Spherical roller bearing feature a large load rating and self-aligning capability
This type of bearing is suitable for low- or medium speed applications which involve heavy or impact loading.
1.These bearings are divided into R, RH(R) and RHA types, which differ in internal structure.
2.Each type can be produced with a cylindrical bore or tapered bore.
Bearings with a tapered bore can be fit and removed easily using an adapter assembly or withdrawal sleeve.
The rate of taper is equivalent among all bearing series.
240 and 241 series 1:30 (supplementary code "K30")
Others 1:12 (supplementary code "K")
3.Application:
1.papermaking machinery, deceleration device, railway vehicle axle, rolling mill, roller gearbox,crusher,
vibrating screen, printing machinery, woodworking machinery, various industrial reducer,
vertical insert self-aligning bearing
2.Spherical Roller Bearings are suitable for the high axial , impulse and heavy load applications
such as paper manufacturing, rolling and other large size machineries.
4.Material:
Material :cage--machinable brass ,roller\ outer ring \ inner ring -- hard chrome steel Gcr15
5.Feature:
1.Spherical roller bearings comprising barrel-shaped convex rollers, double-row inner ring and outer ring are classified into three types: R(RR), RH(RHR) and RHA, according to their internal structure.
2.With the bearing designed such that the circular arc center of the outer ring raceway matches
with the bearing center, the bearing is self-aligning, insensitive to errors of alignment of the shaft relative to the housing, and to shaft bending.
3.This type can accommodate radial load and axial load in both directions, which makes it especially
suitable for applications in which heavy load or impact load is applied.
4.The tapered bore type can be easily mounted/dismounted by using an adapter or withdrawal sleeve.
