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

The FAG 2316 -K-M-C3 double-row self-aligning ball bearing (80x170x58 mm) compensates for misalignment and features a tapered bore and a solid brass cage.

This 2316 -K-M-C3 double-row self-aligning ball bearing is based on a common hollow-spherical raceway in the outer ring. As a result, the component aligns itself automatically during operation and continuously compensates for misalignment, skewing and shaft deflection. Manufactured from standard roller bearing steel 100Cr6 and featuring an open design without an abiding seal, it is suitable for a wide range of applications in the temperature range from -30 to +150 degrees, provided it is supplied with lubricating oil or roller bearing grease as required.

What is the 2316 -K-M-C3 self-aligning ball bearing suitable for in operation?

Shaft mountings with longer support spans or flexible housing structures benefit directly from the angularly adjustable design. The bearing primarily accommodates high radial loads whilst simultaneously tolerating axial forces in both directions, without causing localised edge pressures on the rolling elements. This reduces friction effects during dynamic deflection and promotes smooth mechanical operation in the event of angular misalignment of the rotating shaft.

What properties do the brass cage and tapered bore offer in the 2316 -K-M-C3?

The suffix ‘K’ denotes the tapered internal bore with a ratio of 1:12. This geometry enables precise mounting on tapered shaft seats or friction-fit mounting with clamping sleeves on cylindrical shafts. The fitted brass cage, designated by the letter M, guides the double-row arrangement of rolling elements stably within the raceways, even under severe oscillations and vibrations. Thanks to the factory-set increased radial bearing clearance (C3), sufficient radial bearing clearance remains after the inner ring has expanded radially during tightening, ensuring safe thermal compensation during operation.
