Design of Spherical roller bearings

MB design

These bearings have a central fixed rib, an one-piece cage guided on the inner ring rib.

MA design

These bearings have a central fixed rib and machined cages quided on the inner ring rib.

C design

These bearings have a central guide rib floating on the inner ring, symmetrical rollerswith largerdimensionssothat the load carrying capacity increases. Special pressed sheet cage. Bearingsofthisdesign areof small and medium sizes. 

CA design

These bearings have side shoulders and central guide rib floating on the inner ring, symmetrical rollers with larger dimensions so that the load carrying capacity increases. They also have an one-piece machined brass cages. This design is available for medium and large-sized bearings.

Cages :

Small and medium size spherical roller bearings are fitted with pressed sheet or machined brass cages (Y).Bearings of normal design are fitted with machined brass or steel cages guided on the rollers (M), inner ring (MB) or outer ring raceway (MA).

Glass fibre reinforced polyamide 6.6 cages are success-fully used for small and medium size bearings if the operating temperature doesn't exceed +120?C.

Large-size bearings are fitted with machined brass cages, CA design.

Designs and some technical data are given in table 4.
