Spherical Roller Bearings SKF 24124 CC/C4W33

The SKF 24124 CC/C4W33 self-aligning roller bearing, with dimensions of 120x200x80 mm and a C4 clearance, offers high load-carrying capacity under thermal expansion.

The SKF 24124 CC/C4W33 self-aligning roller bearing is a double-row roller bearing made from standard 100Cr6 bearing steel. With a bore of 120 mm, an outer diameter of 200 mm and a width of 80 mm, this design accommodates heavy radial loads as well as combined axial forces. Thanks to the spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation, thereby preventing edge stresses.

In which installation situations does the 24124 CC/C4W33 self-aligning roller bearing prove its worth?

Bearing arrangements subject to heavy radial and combined axial forces constitute the typical field of application for this series. Thanks to the significantly increased radial clearance (C4), this design is intended for operating conditions involving significant heating or temperature differences between the inner and outer rings. The temperature range of -30 to +200 degrees covers demanding thermal environmental conditions. The lubrication groove with lubrication holes on the outer ring in accordance with W33 facilitates the supply of lubricant directly into the bearing interior.

What do C4 radial clearance and tolerance class P5 mean for bearing selection?

The C4 classification denotes a radial bearing clearance that is significantly greater than normal bearing clearance. This ensures that sufficient movement is maintained for the rolling elements, even with tight fits on the shaft and significant thermal expansion. Furthermore, this model combines the standard dimensional accuracy PN for the connecting dimensions with the enhanced running accuracy P5. The integrated sheet steel cage guides the rollers with low friction, whilst the open profile is designed for external lubrication systems.
