Spherical Roller Bearings SKF 23228 CCK/W33

The SKF 23228 CCK/W33 self-aligning roller bearing, measuring 140 x 250 x 88 mm, offers high radial load-carrying capacity even when the shaft is misaligned.

The SKF 23228 CCK/W33 self-aligning roller bearing is a double-row roller bearing designed for heavy mechanical loads. With a bore of 140 mm, an outside diameter of 250 mm and a width of 88 mm, this roller bearing is suitable for demanding industrial applications. SKF manufactures the bearing from standard roller bearing steel (100Cr6) in the Explorer design. The open-type unit features a sheet steel cage and is designed for operating temperatures ranging from -30 to +200 degrees.

What loads and misalignments does the 23228 CCK/W33 self-aligning roller bearing compensate for?

This self-aligning roller bearing automatically compensates for misalignment and shaft deflection during operation. The design, featuring two symmetrical rows of rollers, is engineered to accommodate high radial forces whilst also withstanding axial forces on both sides. This design is suitable for bearing arrangements subject to heavy shaft loads without fixed alignment. As it is an open bearing, the system can be flexibly integrated with external lubrication systems.

What is the function of the tapered bore and the W33 design?

The designation CCK refers to the tapered bore with a taper ratio of 1:12. This design facilitates mounting on tapered shaft seats or using clamping and withdrawal sleeves. The designation W33 indicates a circumferential lubrication groove with lubrication holes in the outer ring. This enables a uniform supply of lubricant directly into the interior of the bearing. With a running accuracy of P5, this bearing also meets increased requirements for concentricity.
