Spherical Roller Bearings SKF 24052 CC/C3W33

The SKF 24052 CC/C3W33 self-aligning roller bearing (260x400x140 mm) offers increased C3 bearing clearance, P5 running accuracy and an integrated W33 lubrication groove for heavily loaded industrial shafts.

The SKF 24052 CC/C3W33 self-aligning roller bearing accommodates heavy radial loads as well as simultaneously acting axial forces and automatically compensates for shaft misalignment. With key dimensions of a 260 mm bore, 400 mm outer diameter and 140 mm width, this open roller bearing is suitable for large-scale machinery. The 100Cr6 steel used in its manufacture ensures dimensional stability at operating temperatures between –30 and +200 degrees Celsius. The sheet steel cage guides the rolling elements stably along their raceways.

What is the 24052 CC/C3W33 spherical roller bearing suitable for in industrial plants?

This large bearing is primarily used on heavily loaded shafts and heavy-duty drives where high radial forces and shaft deflection occur. Thanks to the spherical outer ring raceway, the bearing can adjust to misalignment between the housing and the shaft. As it is an open design, it can be integrated directly into centralised lubrication systems or housing-side oil and grease circulation systems.

What do the C3 bearing clearance and the W33 lubrication groove mean for model 24052?

The suffix C3 indicates increased radial clearance. This feature counteracts stress when operating temperatures of up to +200 degrees Celsius or tight fits cause thermal expansion of the shaft and inner ring. The designation W33 refers to a lubrication groove with lubrication holes in the outer ring, allowing lubricant to reach directly between the roller sets. The P5 tolerance class also offers increased running accuracy during continuous rotation.
