Spherical Roller Bearings SKF 23136 CCK/C3W33

The SKF 23136 CCK/C3W33 spherical roller bearing compensates for misalignment with a shaft diameter of 180 mm and accommodates heavy radial loads.

This double-row roller bearing, made from standard bearing steel (100Cr6), handles heavy loads and accommodates shaft deflection and misalignment via its spherical outer ring raceway. With a bore of 180 mm, an outer diameter of 300 mm and a width of 96 mm, this open bearing is suitable for demanding industrial drives. The version with a sheet steel cage is suitable for a temperature range of –30 to +200 degrees Celsius. Thanks to its increased running accuracy (P5) combined with standard dimensional accuracy (PN), the bearing operates very smoothly even under continuous load.

What is the 23136 CCK/C3W33 spherical roller bearing suitable for in operation?

Design engineers and maintenance personnel typically use this size in heavy-duty industrial applications, large drives or highly loaded shaft bearings where static and dynamic misalignments occur. As the bearing is of an open design, the installation point requires an external housing seal as well as a targeted lubricant supply. The suffix W33 indicates that the outer ring has an integrated lubrication groove with lubrication holes. This facilitates relubrication directly via the bearing housing, without the grease having to penetrate the entire internal bearing space from the side.

What are the advantages of a tapered bore and C3 clearance?

The designation K stands for a tapered bore with a ratio of 1:12. You can mount the bearing either on a tapered shaft seat or, using a clamping or withdrawal sleeve, on cylindrical shafts. The tight fit is achieved by axially sliding the inner ring onto the shaft, which reduces the internal radial clearance. To prevent seizing despite this tight press fit and possible thermal expansion during operation, the component is supplied ex works with the slightly increased C3 bearing clearance class.
