Spherical Roller Bearings SKF 23024 CC/C3W33

The SKF 23024 CC/C3W33 spherical roller bearing automatically compensates for misalignment during operation with a 120 mm bore and an 180 mm outer diameter.

The 23024 CC/C3W33 self-aligning roller bearing is a double-row roller bearing for industrial applications involving combined loads. Designed as an open bearing, it allows for flexible lubricant selection once installed. The manufacturer, SKF Rolling Bearings, produces this model from standard rolling bearing steel (100Cr6) with a sheet steel cage. With dimensions of 120 mm inner diameter, 180 mm outer diameter and 46 mm width, the component withstands high radial forces as well as axial forces on both sides, whilst compensating for shaft misalignment.

How does the 23024 CC/C3W33 self-aligning roller bearing compensate for misalignment?

This self-aligning roller bearing is suitable for mounting positions subject to high radial loads and shaft deflection. The barrel-shaped rollers run on a common spherical outer ring raceway. This geometry compensates for misalignment between the shaft and housing without causing additional friction. Thanks to the permissible operating temperature range of -30 to +200 degrees, the dimensional stability of the steel is maintained even at elevated temperatures and under varying environmental conditions in industrial applications.

What is the function of C3 bearing clearance and the W33 lubrication groove?

The design with a slightly increased radial clearance (C3) counteracts stress when temperature differences occur between the inner and outer rings or when tight fits cause the inner ring to expand. The designation W33 denotes a circumferential lubrication groove with lubrication holes in the outer ring. This feed allows lubricant to enter directly into the bearing interior between the rows of rollers. In combination with P5 running accuracy and PN standard tolerance, the component supports low-vibration shaft mountings.
