Self-Aligning Ball B. SKF 2310 /C3

The SKF 2310/C3 self-aligning ball bearing, measuring 50x110x40 mm, compensates for misalignment and provides thermal reserves thanks to its C3 clearance.

The 2310 /C3 self-aligning ball bearing is a double-row rolling bearing with a common hollow-spherical outer ring raceway and a cylindrical bore. Thanks to this design, the bearing automatically compensates for misalignment and shaft deflection during operation. The component is manufactured by SKF and is made from standard roller bearing steel 100Cr6 in tolerance class P0 or ABEC 1. It is primarily used where misalignment between housings or dynamic shaft movements occur.

What is the 2310/C3 self-aligning ball bearing suitable for?

This double-row roller bearing is suitable for designs in which shafts deflect elastically or where manufacturing tolerances lead to axial misalignment. Typical applications are found in general mechanical engineering, particularly in long shaft guides and in designs with potential misalignments. Thanks to the integrated sheet steel cage and the permissible temperature range of –30 to +150 degrees, the component primarily absorbs radial and moderate axial forces, thereby preventing edge pressures on the rolling elements.

What are the advantages of the C3 bearing clearance in the 2310 self-aligning ball bearing?

The /C3 designation indicates a slightly increased radial bearing clearance compared with the standard version. This increased clearance between the balls and raceways is beneficial when temperature differences arise between the inner and outer rings during operation, or when tight fits cause the inner ring to expand. As this is an open design without integrated sealing washers, the component requires external sealing of the bearing housing as well as a targeted supply of lubricant, such as grease or lubricating oil.
