Spherical Roller Bearings SKF 23136 CCK/W33

The SKF 23136 CCK/W33 spherical roller bearing, measuring 180 × 300 × 96 mm, compensates for misalignment and accommodates high combined loads.

The SKF 23136 CCK/W33 self-aligning roller bearing is a double-row, open roller bearing designed for heavy-duty industrial applications. With a bore of 180 mm, an outer diameter of 300 mm and a width of 96 mm, this bearing accommodates high radial forces whilst withstanding axial loads in both directions. The Explorer-quality version, made from standard 100Cr6 rolling-bearing steel, features a standard radial clearance and a sheet steel cage. The permissible operating temperature range is from –30 to +200 degrees Celsius.

How does the 23136 CCK/W33 self-aligning roller bearing compensate for misalignment and loads?

This self-aligning roller bearing is used in bearing arrangements where shaft deflection or misalignment occurs. Thanks to the hollow-spherical outer ring raceway, the roller set adjusts angularly and compensates for misalignment between the shaft and housing without causing harmful edge pressure. The integrated lubrication groove, complete with lubrication holes in the outer ring in accordance with the W33 specification, allows for relubrication whilst the bearing is installed, enabling lubricant to reach directly between the rows of rollers.

What are the special features of the tapered bore during assembly?

The CCK design features a tapered internal bore with a taper ratio of 1:12. This design enables mounting on tapered shaft seats or, using suitable mounting and withdrawal sleeves, on cylindrical shafts. The axial fit allows the bearing clearance to be precisely adjusted. The combination of dimensional accuracy to PN class and running accuracy to P5 class ensures low-vibration operation under working conditions.
