Spherical Roller Bearings SKF 23152 CC/C2W33

The SKF 23152 CC/C2W33 spherical roller bearing, measuring 260 × 440 × 144 mm and featuring a lubrication groove and C2 clearance, offers high load-carrying capacity for demanding heavy-duty applications.

The 23152 CC/C2W33 self-aligning roller bearing is an open roller bearing designed for industrial applications involving high radial forces and axial loads acting in both directions. SKF manufactures this bearing from standard roller bearing steel (100Cr6) with a bore of 260 mm, an outer diameter of 440 mm and a width of 144 mm. Thanks to its angular contact design, the bearing automatically compensates for misalignment and shaft deflection during operation, thereby preventing edge stresses.

In which installation situations does the 23152 CC/C2W33 self-aligning roller bearing prove its worth?

This rolling bearing is designed for heavy-duty applications where shafts exhibit elastic deflection under load or where there are misalignments between the housing seats. A sheet steel cage keeps the symmetrical barrel rollers spaced apart. To ensure effective relubrication, the outer ring features a circumferential lubrication groove with lubrication holes in accordance with the W33 designation, which facilitates the delivery of lubricant directly into the rolling zone.

What is the significance of C2 bearing clearance and P5 running accuracy?

The bearing features reduced radial clearance (C2). Such reduced clearance is recommended when particularly low-play guidance of the shaft is required and only minor differences in thermal expansion occur between the inner and outer rings. In combination with the increased running accuracy P5 and standard dimensional accuracy PN, the bearing ensures smooth and low-vibration operation. The unsealed design covers a temperature range from -30 to +200 degrees and requires an external sealing system within the housing.
