Spherical Roller Bearings SKF 24024 CC/W33

The SKF 24024 CC/W33 self-aligning roller bearing, measuring 120 x 180 x 60 mm, offers high load-carrying capacity and angular misalignment capability under combined loads.

The SKF 24024 CC/W33 self-aligning roller bearing is a rolling bearing designed for demanding industrial applications. With a bore of 120 mm, an outer diameter of 180 mm and a width of 60 mm, this open bearing can simultaneously accommodate very high radial loads and axial forces acting in both directions. The design automatically compensates for misalignment and shaft deflection. As part of the Explorer series, the bearing is characterised by the optimised material properties of 100Cr6 rolling-element bearing steel.

In which installation situations does the 24024 CC/W33 self-aligning roller bearing prove its worth?

Its use is recommended for high radial and axial loads where misalignment or shaft deflection occurs. The spherical raceway in the outer ring allows for angular compensation of misalignment between the inner and outer rings during operation.

Thanks to its open design without integrated seals, the bearing is designed for operating temperatures ranging from -30 to +200 degrees Celsius. The sheet steel cage guides the rollers during continuous rotational movement.

What are the functions of the W33 lubrication groove and the P5 running accuracy?

The designation W33 refers to a circumferential lubrication groove with lubrication holes in the outer ring. This design facilitates relubrication whilst the bearing is installed, as the lubricant reaches the area of the roller rows directly and is distributed there.

The combination of standard dimensional accuracy PN and the tighter-toleranced running accuracy P5 enables uniform concentricity with standardised mounting dimensions. As an open bearing with standard radial clearance, the design requires application-specific coordination of the housing seal and lubricant.
