Self-Aligning Ball B. FAG 2316 -M-C3

The double-row self-aligning ball bearing 2316 -M-C3 compensates for misalignment during operation and, with an 80 mm bore and a brass cage, offers high mechanical stability.

The 2316 -M-C3 self-aligning ball bearing is a double-row rolling bearing with a hollow-spherical outer ring raceway, manufactured by FAG Wälzlager. With key dimensions of 80 mm bore diameter, 170 mm outer diameter and 58 mm width, it is suitable for demanding industrial applications. Thanks to the symmetrical arrangement of the two rows of balls, the bearing automatically adjusts to shaft deflection. The 100Cr6 material ensures dimensional stability at operating temperatures between –30 and +150 degrees Celsius.

What is the 2316 -M-C3 self-aligning ball bearing suitable for in industrial applications?

The 2316 -M-C3 self-aligning ball bearing is particularly useful where shaft deflection or misalignment between the housing and the shaft needs to be compensated for. Thanks to the spherical raceway in the outer ring, the rolling elements pivot with the inner ring away from the centre position, thereby helping to prevent edge stresses. Typical applications include shaft mountings prone to misalignment or housing offset. As this is an open bearing, the lubricant can be flexibly adapted to the specific operating environment.

What is the function of the brass cage and the C3 radial clearance in this bearing?

The version with the suffix -M-C3 combines a solid brass cage with the increased radial clearance class C3. The brass cage guides the rolling elements along their raceways whilst maintaining dimensional stability, even under acceleration and thermal stress. At the same time, the C3 bearing clearance provides additional space between the balls and raceways. This clearance counteracts stresses should temperature differences arise between the inner and outer rings, or should tight fits reduce the bearing clearance after installation. The tolerance class P0 or ABEC 1 ensures a precise fit.
