Spherical roller bearings are designed to sustain heavy loads, shaft misalignment and deﬂection. They contain two symmetrical or asymmetrical rows of barrel-shaped rollers, which align themselves in the outer race sphered track. They are, therefore, able to carry very heavy radial loads and axial loads in either direction.

Roller guidance is achieved by the ﬁxed ﬂanges on the inner ring for the CA, EX, MB, VS and MA - design or a ﬂoating ring for the C design. For further information, see roller guidance design on next page.

EX : 1 piece brass cage, roller guided between 2 inner ring ﬂanges. Cage is guided on the rollers. Assymetrical roller position.

C : 2 pressed sheet steel cages, roller guided on a ﬂoating rings.

CA : 1 piece brass cage, roller guided between 2 inner ring ﬂanges. Cage is guided on the rollers. Assymetrical roller position.

MB : 2 piece brass cage, roller guided between 2 inner ring ﬂanges and one central rib. Cage is guided on the inner ring.

VS C4 F80 : 1 piece brass cage, roller guided between 2 inner ring ﬂanges. Cage is guided on the outer ring.

MA C4 F80 : 2 piece brass cage, roller guided between 2 inner ring ﬂanges and one central rib. Cage is guided on the outer ring.

C 2RS : Steel cage with 2 NBR seals

EX meet the higher exigency of the market. EX bearings are produced with higher grade steel, enhanced heat treatment process, higher machining accuracy and better surface roughness. These improvements are resulting in bearings that run with less noise and less vibrations and have a improved energy efﬁciency.

C 2RS type is a sealed spherical roller bearing with a steel cage C and 2 NBR seals. High temperature seals 2VS are available as well. Sealed bearings are ﬁlled with lithium based grease. Due to the seal, misaligment is reduced. As well for some types the bearing with differs from the standard width.

Spherical roller bearings are manufactured with tapered bore-K(1:12) and K30 (1:30) with lubrication groove and 3 lubrication holes on the outside diameter W33. All our sphericals have the W33 feature.

Tolerances

Spherical roller bearings with cylindrical and tapered bore are generally manufactured to “PO” precision class. Radial Clearance

Spherical roller bearings with cylindrical and tapered bore are generally manufactured to normal (CN), C2, C3, C4 and C5 clearances. Heat Treatment

Spherical roller bearings with outside diameter D>240mm of all series given in this catalog can be used to an operating temperature of +150°C (+302°F). Small size bearings operate normally at temperatures up to +120°C (+248°F).
