Self-Aligning Ball B. FAG 2315 -M-C3

The FAG 2315 -M-C3 self-aligning ball bearing with a 75 mm bore compensates for misalignment and copes with demanding industrial applications thanks to its brass cage and C3 clearance.

The double-row 2315 -M-C3 self-aligning ball bearing is an open rolling bearing made from standard bearing steel (100Cr6). The design is characterised by a common hollow-spherical raceway in the outer ring. This allows the bearing to self-align automatically in the event of shaft misalignment. With an outer diameter of 160 mm and a width of 55 mm, this rolling bearing is particularly suitable for designs where shaft deflection occurs or where misalignment between bearing housings needs to be compensated for.

In which applications is the 2315 -M-C3 self-aligning ball bearing used?

This design is particularly suitable for bearing locations where shafts deflect elastically or where misalignment between the housing seats is present. Typical applications include long shaft guides and bearing arrangements with separate housings. The component primarily absorbs radial loads as well as low axial forces in both directions. As this is an open bearing without integrated sealing washers, lubrication is provided via the housing design, for example through external oil or grease lubrication.

What properties do the brass cage and C3 clearance offer?

The suffix ‘M’ refers to a guided solid brass cage. This cage material is designed for use in applications involving severe vibrations and high acceleration forces. In combination with the permissible temperature range of –30 to +150 degrees, the component also performs reliably under thermally demanding conditions. The slightly increased radial bearing clearance (C3) helps to ensure that the internal operating clearance does not narrow to an impermissible extent when the bearing heats up or due to tight fits on the shaft and housing.
