Self-Aligning Ball B. FAG 2213 -K-TVH-C3

FAG 2213 -K-TVH-C3 self-aligning ball bearing: a double-row rolling bearing with a 65 mm tapered bore, C3 clearance and a polyamide cage to compensate for misalignment.

The 2213 -K-TVH-C3 from FAG is a double-row roller bearing made from standard roller bearing steel (100Cr6) with the main dimensions of a 65 mm bore, 120 mm outer diameter and 31 mm width. Thanks to the shared spherical raceway in the outer ring, the design flexibly compensates for misalignment and angular misalignment between the shaft and housing. As an open bearing, this version is designed for external lubrication systems and covers an operating temperature range from –30 to +120 degrees.

What is the 2213 -K-TVH-C3 self-aligning ball bearing suitable for?

This double-row rolling bearing is designed for shaft mountings and drives where elastic deflection or misalignment occurs. The oscillating ball row helps to prevent excessive edge pressures in the event of angular misalignment and promotes low-friction concentricity.

The open design is intended for use in protected housings with oil or grease lubrication. In designs with larger bearing clearances or dynamic loads, the angular mobility compensates for installation inaccuracies.

What do ‘tapered bore’ and ‘C3 clearance’ mean for this bearing?

The suffix ‘K’ denotes a tapered inner ring bore with a taper ratio of 1:12. This allows the bearing to be mounted directly onto tapered shaft journals or, using a suitable adapter sleeve, onto cylindrical shafts.

During press-fitting, the bearing clearance is reduced due to the design. This is where the C3 feature comes into play: the slightly increased radial clearance helps to ensure that, after axial press-fitting, sufficient operating clearance remains for smooth running. The dimensionally stable polyamide cage (TVH) guides the balls quietly in tolerance class P0/PN.
