Spherical Roller Bearings SKF 23048 CC/W33

The SKF 23048 CC/W33 spherical roller bearing compensates for misalignment, measures 240 × 360 × 92 mm and features lubrication holes in the outer ring.

The 23048 CC/W33 self-aligning roller bearing simultaneously accommodates high radial loads and axial forces acting in both directions. This double-row roller bearing from SKF is suitable for demanding industrial applications involving misalignment or shaft deflection. Thanks to the spherical raceway in the outer ring, the barrel rollers can be adjusted to compensate for misalignment. Measuring 240 x 360 x 92 mm, this open bearing serves as either a floating or fixed bearing. It is suitable for applications where operational reliability and ease of maintenance are paramount.

In which applications is the 23048 CC/W33 self-aligning roller bearing used?

This bearing is used in industrial drive trains and machine components where high radial loads occur. As shafts can deflect elastically under load, the spherical roller design automatically compensates for misalignment between the inner and outer rings. The open bearing requires a lubricating housing system and is designed for continuous operation at temperatures ranging from –30 to +200 degrees. The design promotes even load distribution within the system.

What characteristics do the W33 designation and tolerance class P5 offer?

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. This allows lubricant to reach directly between the rows of rollers. Tolerance class P5 offers increased running accuracy compared with the standard tolerance and reduces vibrations during continuous operation. When combined with the sheet steel cage and standard radial bearing clearance, the component can be mounted precisely on cylindrical shaft seats with a diameter of 240 mm.
