Self-Aligning Ball B. FAG 1310 -K-TVH-C3

The FAG 1310 -K-TVH-C3 double-row self-aligning ball bearing, measuring 50 × 110 × 27 mm, compensates for misalignment and has a tapered bore.

The 1310 -K-TVH-C3 self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) with a continuous hollow-spherical outer ring raceway. This design means that the bearing automatically adjusts itself within the housing in the event of shaft deflection or misalignment. Designed as an open bearing without an integrated seal, this FAG variant allows for targeted lubrication via the surrounding system. The integrated polyamide cage ensures quiet guidance of the rolling elements.

What is the 1310 -K-TVH-C3 self-aligning ball bearing suitable for?

Design engineers and maintenance personnel use this design primarily in bearing locations where operational shaft deflection or misalignment between the housing seats occurs. Thanks to its double-row ball arrangement, the unit accommodates radial forces as well as moderate axial loads in both directions. Typical applications can be found in general mechanical engineering as well as in long drive shafts, where manufacturing tolerances or elastic deformations in the structure need to be compensated for.

What are the special features of a tapered bore and C3 clearance?

The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12. This allows mounting on truncated shafts or, by means of clamping or withdrawal sleeves, on smooth cylindrical shafts. When the inner ring is pushed onto the shaft, it expands, which specifically reduces the existing bearing clearance. For this reason, the bearing is factory-fitted with a slightly increased radial bearing clearance (C3), so that the required operating clearance remains after the force-fit assembly.
