Self-Aligning Ball B. SKF 2312 K

The SKF 2312 K double-row self-aligning ball bearing with a tapered bore flexibly compensates for misalignment and measures 60 x 130 x 46 mm.

The SKF 2312 K self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6). Thanks to the spherical raceway in the outer ring, the bearing automatically compensates for angular misalignment between the shaft and housing. This open design has a standard radial clearance and operates within a temperature range of -30 to +150 degrees. A sheet steel cage guides the rolling elements evenly in both rows.

In which applications does the 2312 K self-aligning ball bearing compensate for misalignment?

Design engineers primarily use this bearing where shaft deflection or misalignment may occur. Thanks to its angular movement capabilities, the 2312 series compensates for static and dynamic misalignment without unnecessarily increasing friction. Typical applications can be found in general mechanical engineering and in long drive shafts. As the bearing is of an open design, you can integrate it directly into existing lubrication circuits or use specific relubrication intervals.

What are the advantages of the bearing’s tapered bore?

The designator ‘K’ indicates a tapered bore with a taper ratio of 1:12. This tapered shape allows for mounting directly onto tapered shaft seats or, using suitable mounting and withdrawal sleeves, onto smooth shafts. During mounting, you can reduce the radial bearing clearance in a controlled manner, allowing the interference fit on the shaft to be precisely adjusted. The bearings are manufactured to the standard tolerance class P0/PN (corresponding to ABEC 1).
