Spherical Roller Bearings SKF 23044 CCK/W33

The SKF 23044 CCK/W33 spherical roller bearing, with dimensions of 220 × 340 × 90 mm, can withstand high radial loads and, by design, compensates for misalignment.

The 23044 CCK/W33 self-aligning roller bearing is part of the SKF Explorer range and is designed for demanding industrial applications. Manufactured from standard 100Cr6 rolling-bearing steel, this open bearing features a standard radial clearance and a robust sheet-steel cage. The design accommodates shaft deflection and misalignment between the inner and outer rings. For relubrication, the outer ring features an integrated lubrication groove with lubrication holes (W33).

For which operating conditions is the 23044 CCK/W33 self-aligning roller bearing suitable?

This bearing is primarily used in heavily loaded industrial drives and heavy-duty shaft mountings. The self-aligning roller bearing design proves its worth wherever high radial loads occur and shaft misalignment needs to be compensated for. With a permissible temperature range of –30 to +200 degrees, the bearing also copes with environments subject to thermal stress during operation.

What are the special features of the tapered bore and the W33 designation?

The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12. This design facilitates mounting on tapered shaft seats or, with the aid of suitable mounting and withdrawal sleeves, on cylindrical shafts. The desired radial clearance can be adjusted during mounting. The W33 feature allows direct lubricant supply via the outer ring straight into the interior of the rolling elements, which simplifies maintenance.
