Spherical Roller Bearings SKF 24032 CCK30/W33

The SKF 24032 CCK30/W33 spherical roller bearing, with main dimensions of 160 × 240 × 80 mm, effectively accommodates high radial loads and misalignment.

This double-row self-aligning roller bearing, type 24032 CCK30/W33, belongs to the SKF Explorer performance class and is made from standard rolling-element bearing steel (100Cr6). As an open roller bearing without sealing rings, it is designed for use in a temperature range from -30 to +200 degrees. The design combines standard dimensional accuracy (PN) with enhanced running accuracy to tolerance class P5. Thanks to the integrated circumferential groove and lubrication holes in the outer ring, lubricants are fed directly between the two rows of rollers.

What is the 24032 CCK30/W33 self-aligning roller bearing suitable for?

Design engineers primarily use this design for heavy-duty industrial bearings subjected to high radial forces and deflections. The self-aligning bearing automatically compensates for static and dynamic angular misalignments between the inner and outer rings without causing additional edge pressures on the rolling elements. The integrated sheet steel cage guides the symmetrical spherical rollers with minimal vibration and keeps friction low even at high operating pressures. Thanks to the through-hardened bearing steel, the bearing can also withstand uneven shock loads during continuous, long-term operation.

Why is the K30 tapered bore crucial for this self-aligning roller bearing?

The design with a taper ratio of 1:30 (designation suffix K30) facilitates mounting on tapered shaft seats or using suitable mounting and withdrawal sleeves. By sliding the bearing axially onto the taper to a defined extent, you can precisely set the remaining operating radial clearance. As the normal bearing clearance is reduced during press-fitting, you must carefully measure the residual radial clearance during the mounting process. The W33 lubrication groove in the outer ring also helps to ensure that fresh lubricant reaches all rolling elements directly.
