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 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).
