Spherical Roller Bearings SKF 23088 CAK/W33

The SKF 23088 CAK/W33 self-aligning roller bearing, with its tapered bore and brass cage, offers a high-load-capacity solution for heavy-duty industrial applications with a shaft diameter of 440 mm.

The SKF 23088 CAK/W33 self-aligning roller bearing is a double-row large-size bearing designed for high radial and axial loads. With key dimensions of a 440 mm bore, 650 mm outside diameter and 157 mm width, the bearing automatically compensates for misalignment. The standard rolling bearing steel 100Cr6 gives the raceways high wear resistance. The open design allows for direct integration into centralised lubrication systems.

What loads can the 23088 CAK/W33 self-aligning roller bearing accommodate?

This large-diameter rolling bearing is primarily used in heavy machinery and plant engineering where shaft deflection or housing displacement occurs. Typical applications include industrial gearboxes and heavily loaded large machines subject to high static and dynamic forces. The bearing accommodates misalignment between the inner and outer rings without adversely increasing friction. The brass cage guides the rolling elements stably along the raceway, even under severe vibrations and shock loads.

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

The designation ‘K’ indicates a tapered bore with a taper ratio of 1:12. This design allows for direct mounting on tapered shaft seats or flexible installation on cylindrical shafts using clamping or withdrawal sleeves. The axial displacement allows the bearing clearance to be precisely adjusted during press-fitting. The designation W33 indicates a lubrication groove with lubrication holes in the outer ring, through which lubricant is fed directly between the two rows of rollers.
