Spherical Roller Bearings SKF 24028 CC/W33

The SKF 24028 CC/W33 spherical roller bearing compensates for misalignment under heavy loads and measures 140 × 210 × 69 mm.

The SKF 24028 CC/W33 self-aligning roller bearing is a double-row roller bearing for industrial applications involving combined loads. The barrel rollers run on a common hollow-spherical outer ring raceway, which automatically compensates for shaft deflection and misalignment during operation. The bearing accommodates high radial loads as well as axial forces on both sides. Manufactured from 100Cr6 bearing steel, the Explorer version offers high load-carrying capacity in a compact design.

What is the 24028 CC/W33 self-aligning roller bearing suitable for?

This bearing is primarily used in industrial mechanical engineering where angular misalignment or shaft deflection needs to be compensated for. It is designed for mounting positions subject to high radial forces and simultaneous axial loads. The integrated sheet steel cage guides the rollers along the raceway even under dynamic loads. Design engineers use the 240 series primarily in applications where a shaft diameter of 140 mm needs to be supported within a confined radial installation space.

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

The W33 version features a circumferential lubrication groove with lubrication holes in the outer ring, which facilitates the direct supply of lubricant into the interior of the bearing. Combined with the increased running accuracy to tolerance class P5, this supports low-vibration operation of the shaft. As this is an unsealed, open bearing, sealing is provided by the surrounding housing. The permissible operating temperature range is between -30 and +200 degrees Celsius.
