Spherical Roller Bearings SKF 23244 CC/W33

The SKF 23244 CC/W33 spherical roller bearing (220x400x144 mm) can accommodate high radial loads and compensates for shaft misalignment.

The 23244 CC/W33 self-aligning roller bearing is designed for heavy-duty industrial applications involving combined loads. SKF manufactures this design from standard rolling-element bearing steel (100Cr6) with two rows of barrel-shaped rollers on a common hollow-spherical outer ring raceway. Thanks to this design, the bearing compensates for misalignment between the shaft and the housing. As an open bearing, it can be integrated into existing lubrication systems and operates within a temperature range of -30 to +200 degrees.

What loads can the 23244 CC/W33 self-aligning roller bearing accommodate?

The self-aligning roller bearing is designed for high radial forces whilst simultaneously withstanding axial loads. It is used in heavy-duty bearing applications where elastic shaft deflection may occur. Thanks to the spherical outer ring raceway, the set of rollers adjusts its angular position without generating impermissible edge stresses. The integrated sheet steel cage guides the rolling elements under varying operating conditions. A seal on the housing side must be provided for use in damp or dusty environments.

What are the distinctive features of the CC/W33 designation?

The suffix W33 refers to an integrated lubrication groove with lubrication holes in the outer ring. This facilitates the even supply of lubricant directly into the housing. The designation CC stands for the internal design featuring window-type sheet steel cages and an inner ring without a guide ring. Furthermore, this component offers increased running accuracy to tolerance class P5 whilst maintaining standard dimensional accuracy PN. The main dimensions for installation are a bore of 220 mm, an outer diameter of 400 mm and a width of 144 mm.
