Spherical Roller Bearings SKF 23026 CC/C3W33

The SKF 23026 CC/C3W33 self-aligning roller bearing, measuring 130 × 200 × 52 mm, offers C3 radial clearance and an integrated lubrication groove for demanding industrial applications.

The 23026 CC/C3W33 self-aligning roller bearing is an open, double-row roller bearing made from standard bearing steel (100Cr6). The design, featuring a hollow-spherical outer ring raceway, automatically compensates for misalignment and shaft deflection during operation. Thanks to the slightly increased C3 bearing clearance, the bearing is suitable for operating conditions involving thermal expansion or tight fits. This version features a sheet steel cage and is designed for operating temperatures ranging from -30 to +200 degrees.

Under what operating conditions is the 23026 CC/C3W33 self-aligning roller bearing required?

This self-aligning roller bearing accommodates high radial forces as well as axial loads acting in both directions. Its symmetrical barrel rollers automatically adjust in the event of misalignment or shaft deflection, thereby preventing excessive edge stresses. As this is an open bearing, protection against contamination and lubricant loss is provided by an external housing seal.

What do the designations CC, C3 and W33 mean for this bearing?

The designation summarises key design features: the abbreviation CC stands for an internal configuration with a guide-free centre ring and pressed sheet steel cages, which reduces friction. The C3 clearance class provides increased radial clearance, ensuring that no impermissible preload develops as a result of operational heating. The W33 designation indicates a circumferential lubrication groove with lubrication holes in the outer ring for the direct supply of lubricant.
