Spherical Roller Bearings SKF 23036 CCK/W33

The SKF 23036 CCK/W33 self-aligning roller bearing combines a 180 mm bore, a 1:12 tapered seat and a W33 lubrication groove for heavy-duty industrial applications.

The SKF 23036 CCK/W33 self-aligning roller bearing is a double-row roller bearing designed for high mechanical loads and to compensate for angular misalignment. With an inside diameter of 180 mm, an outside diameter of 280 mm and a width of 74 mm, the design is suitable for heavy-duty industrial shaft mountings. Manufactured from 100Cr6 rolling-element bearing steel in the SKF Explorer design, the bearing features a standard radial clearance and a robust sheet steel cage. As an open design without integrated seals, the bearing is rated for a temperature range of –30 to +200 degrees.

What loads and operating conditions can the 23036 CCK/W33 self-aligning roller bearing accommodate?

This double-row roller bearing is designed for mounting arrangements subject to high radial forces and axial forces acting in both directions. The barrel-shaped rollers adjust freely within the hollow spherical outer ring raceway, thereby automatically compensating for misalignment and shaft deflection during operation. In conjunction with the improved running accuracy of tolerance class P5 and standard tolerance PN for the main dimensions, the design contributes to low-vibration concentricity under continuous load.

What are the advantages of the tapered bore and the W33 feature?

The tapered internal bore, with a taper ratio of 1:12, allows mounting on tapered shaft seats as well as on cylindrical shafts using clamping or withdrawal sleeves. During axial mounting, the remaining bearing clearance can be precisely controlled by the manner in which the bearing is slid onto the shaft. The W33 feature denotes a circumferential lubrication groove with lubrication holes in the outer ring. This enables the direct supply of lubricant between the rows of rollers in the open bearing and facilitates continuous relubrication.
