Classification | Spherical Roller Bearings |
Spherical roller bearings operate in arduous conditions. The spherical rollers can be symmetrical or unsymmetrical and are self-aligning
in the outer ring sphered raceway. Thus, the possible coaxiality deviations of the supporting bearings as well as shaft bending can be
compensated.
Spherical roller bearings are manufactured in the following constructive versions, depending on the bearing size and series.
MB design
These bearings have a central fixed rib and machined cages guided on the inner ring rib.
MA design
These bearings have a central fixed rib and machined cages guided on the outer ring rib.
C design
These bearings have a central guide rib floating on the inner ring, symmetrical rollers with larger dimensions so that the load
carrying capacity increases. Special pressed sheet cage. Bearings of this design are of small and medium sizes.
CA design
These bearings have side shoulders and an one-piece machined brass cage. They also have symmetrical rollers with larger dimensions
so that the load carrying capacity increases. This design is available for medium and large-sized bearings.
Other constructive versions are shown below:
Cylindrical bore, lubrication groove and holes in the outer ring:
Tapered bore, lubrication groove and holes in the outer ring (taper 1:12,1:30)
