Spherical Roller Bearings SKF 23120 CC/W33

The open SKF 23120 CC/W33 self-aligning roller bearing, measuring 100 × 165 × 52 mm, can accommodate high radial loads and compensates for misalignment during operation.

The SKF 23120 CC/W33 self-aligning roller bearing belongs to the series of double-row spherical roller bearings. Thanks to the hollow spherical raceway of the outer ring, the roller arrangement automatically adjusts to shaft deflection. This design is particularly suitable for bearing arrangements where strong radial forces act on the shaft. Manufactured from standard rolling bearing steel 100Cr6, the component withstands thermal loads ranging from –30 to +200 degrees Celsius.

What is the 23120 CC/W33 self-aligning roller bearing suitable for in operation?

Design engineers prefer this size for applications involving dynamic shaft misalignment. Thanks to its self-aligning function, the roller guide compensates for angular misalignment between the shaft and the housing without causing disruptive edge pressures. As the component is of an open design, it can be connected directly to a central lubrication system or a sealed oil bath. The integrated sheet steel cage guides the rolling elements with minimal vibration and withstands mechanical shock loads.

What are the advantages of the lubrication groove and P5 running accuracy?

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. Maintenance personnel use this to press lubricant directly between the two sets of rollers. This reduces friction and rapidly distributes the lubricant to all contact zones. In addition to the standard dimensional accuracy PN, this design features the enhanced running accuracy P5. The reduced radial runout promotes low-vibration concentricity at higher speeds.
