Self-Aligning Ball B. FAG 2315 -M

The FAG 2315-M double-row self-aligning ball bearing reliably compensates for misalignment in shafts with a diameter of 75 mm thanks to its hollow-spherical outer ring raceway.

The 2315-M self-aligning ball bearing from FAG Rolling Bearings is a double-row rolling bearing with a cylindrical bore for shafts with a diameter of 75 mm. It has an outer diameter of 160 mm and a width of 55 mm. Manufactured from standard rolling-bearing steel 100Cr6, the bearing features a continuous spherical outer ring raceway. Thanks to this geometry, the two rows of balls automatically adjust to any deflection or misalignment of the shaft without significantly affecting smooth running.

In which applications does the 2315-M self-aligning ball bearing compensate for shaft misalignment?

Design engineers and maintenance personnel opt for the 2315-M self-aligning ball bearing when shaft deflection or static misalignment between the housing and the shaft is to be expected. Typical applications include designs with longer spans or flexible frame structures. The rolling bearing primarily absorbs radial loads and can tolerate moderate axial forces in both directions. The open design allows for flexible operation in an oil bath or with grease.

What are the advantages of the brass cage in the -M variant?

The suffix ‘-M’ indicates a solid brass cage that guides the balls precisely. This cage material is recommended over sheet metal or plastic cages, particularly in demanding environmental conditions, where vibrations occur or where there are rapid changes in rotational speed. Combined with the permissible temperature range of -30 to +150 degrees, this design can also cope with thermally demanding processes. The standard radial bearing clearance, in conjunction with standard fits, provides a balanced operating clearance for many industrial applications.
