Spherical Roller Bearings SKF 22236 CCK/W33

The SKF 22236 CCK/W33 self-aligning roller bearing, measuring 180 × 320 × 86 mm, with a tapered bore and lubrication groove, provides a robust bearing solution for heavy radial loads.

The SKF 22236 CCK/W33 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications involving combined loads. With a bore diameter of 180 mm, an outer diameter of 320 mm and a width of 86 mm, this open design accommodates heavy radial forces and axial forces acting in both directions. The crowned rollers and the hollow-spherical outer ring raceway automatically compensate for angular misalignment and shaft deflection during operation. Manufactured from standard 100Cr6 rolling-bearing steel, the bearing operates within a temperature range of -30 to +200 degrees.

What loads can the 22236 CCK/W33 self-aligning roller bearing accommodate?

The design can handle high static and dynamic radial forces as well as simultaneous shock loads. The lubricant can be applied directly into the bearing interior via the lubrication groove with lubrication holes (W33) integrated into the outer ring. The built-in sheet steel cage guides the rolling elements precisely and withstands rapid speed fluctuations. As this is an open design without its own sealing elements, sealing is provided by the surrounding bearing housing.

When is the tapered bore required for bearing 22236 CCK/W33?

The designation CCK refers to a tapered bore with the standard taper ratio of 1:12. This design is used when the bearing is mounted on a clamping or withdrawal sleeve, or directly onto a tapered shaft journal. The axial sliding clearance allows the remaining bearing clearance to be precisely adjusted during assembly. The bearing has standard radial clearance and, with tolerance class P5, offers increased running accuracy with standard dimensional accuracy PN.
