Self-Aligning Ball B. FAG 1316 -K-M-C3

The FAG 1316 -K-M-C3 self-aligning ball bearing, with an 80 mm tapered bore and a double-row design, compensates for misalignment and shaft deflection during operation.

The FAG 1316 -K-M-C3 self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) with a hollow-spherical outer ring raceway. This design automatically compensates for misalignment and shaft deflection during operation. The component has an outer diameter of 170 mm and a width of 39 mm, and complies with tolerance class P0 (normal tolerance). Thanks to its open design, the lubricant can be freely selected and tailored to the specific operating environment.

For which installation situations is the 1316 -K-M-C3 self-aligning ball bearing suitable?

Designs with long shafts or separate bearing housings use this self-aligning ball bearing to compensate for angular misalignment of the shafts without increased edge pressure. The double-row ball arrangement primarily absorbs radial forces and also supports axial forces in both directions. Due to the open design without sealing washers, external sealing of the housing is required, which allows for individual lubrication with grease or oil.

What is the function of the brass cage, the tapered bore and the C3 clearance?

The solid brass cage guides the rolling elements with minimal vibration and, together with the roller bearing steel, is suitable for operating temperatures ranging from -30 to +150 degrees. The increased radial bearing clearance (C3) counteracts seizing if the shaft and bearing rings heat up to different degrees during operation. Furthermore, the radial clearance is reduced when the inner ring is pressed on: the tapered bore with a pitch ratio of 1:12 enables precise mounting on clamping or withdrawal sleeves as well as on tapered shaft seats.
