Self-Aligning Ball B. FAG 2316 -M

The FAG 2316-M self-aligning ball bearing, measuring 80 × 170 × 58 mm and featuring a brass cage, automatically compensates for misalignment and shaft deflection during operation.

The FAG 2316-M self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) for mounting positions with misalignment. With a bore of 80 mm, an outer diameter of 170 mm and a width of 58 mm, the common hollow-spherical outer ring raceway automatically compensates for misalignment between the inner and outer rings. This version has standard radial clearance and a tolerance class of P0/PN (ABEC 1), and is designed for a temperature range of -30 to +150 degrees.

In which bearing positions does the 2316-M self-aligning ball bearing compensate for misalignment?

The double-row bearing is used when operational shaft deflections or misalignments between bearing positions need to be compensated for. By allowing the balls to move freely on the spherical outer raceway, the component prevents damaging edge pressures and keeps rolling resistance low. The standard cylindrical bore allows for direct mounting on the shaft. The open design also allows for the precise adjustment of the lubricant within the surrounding housing.

What is the function of the brass cage in the -M variant?

The suffix ‘-M’ indicates the solid brass cage, which guides the rolling elements at high speeds or under vibration. Brass is a material characterised by high strength and thermal stability within the specified temperature range. As the bearing is of open construction, protection against foreign particles is provided by external housing seals. The targeted supply of lubricant, whether oil or grease, supports the low-friction operation of the components.
