- Spherical roller bearings comprising
barrel-shaped convex rollers, double-row inner ring and outer ring are
classified into four types: R, RH, RHR and RHA, according to their internal
structure.
- 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.
- 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.
- The tapered bore type can be easily
mounted/dismounted by using an adapter or withdrawal sleeve.
