Spherical Roller Bearings SKF 24030 CC/C3W33

The SKF 24030 CC/C3W33 self-aligning roller bearing (150x225x75 mm) withstands heavy radial loads and automatically compensates for shaft misalignment during operation.

The SKF 24030 CC/C3W33 self-aligning roller bearing is a double-row roller bearing designed for demanding drive applications. The barrel-shaped rollers run on a spherical outer ring raceway, which compensates for misalignment between the inner and outer rings. Manufactured from standard roller bearing steel 100Cr6, the unit withstands temperatures ranging from –30 to +200 degrees Celsius. Thanks to its open design without an integrated seal, the bearing can be lubricated directly via the housing system.

In which applications does the 24030 CC/C3W33 spherical roller bearing prove its worth?

Design engineers primarily use this bearing type in heavy-duty industrial applications subject to high radial forces. In such applications, shaft deflection and misalignment frequently occur, which would overload rigid roller bearings. The design, with an outer diameter of 225 mm and a width of 75 mm, offers a high radial load capacity. In addition, the rolling bearing accommodates axial forces in both directions.

What is the function of the designations C3 and W33 for this SKF bearing?

The designation C3 indicates a slightly increased radial clearance. This clearance helps to compensate for stresses caused by operational heating or tight fits on the shaft. The suffix W33 denotes a lubrication groove with lubrication holes in the outer ring, which facilitates the supply of lubricant directly into the bearing interior. The running accuracy to tolerance class P5 also ensures smooth running.
