Self-Aligning Ball B. FAG 2207 -K-TVH-C3

The FAG 2207 -K-TVH-C3 double-row self-aligning ball bearing (35x72x23 mm) compensates for angular misalignment and, thanks to its tapered bore, offers flexible mounting options.

The 2207 -K-TVH-C3 self-aligning ball bearing is a double-row rolling bearing made from standard rolling bearing steel (100Cr6). The hollow-spherical outer ring raceway allows the two rows of balls to compensate for misalignment and elastic shaft deflection during operation. Thanks to its open design, this bearing is suitable for applications where lubrication is supplied via the surrounding housing. A polyamide cage guides the rolling elements within a temperature range of -30 to +120 degrees.

What is the 2207 -K-TVH-C3 self-aligning ball bearing suitable for?

Design engineers primarily use this self-aligning ball bearing where shaft deflection or misalignment between the housing seats may occur. Typical applications include bearing arrangements with long shaft sections or separately mounted housings. As the self-aligning ball bearing compensates for misalignment, it helps to prevent excessive edge pressures on the raceways. The open design without integrated sealing washers allows operation with both grease and in a circulating oil bath.

What are the advantages of a tapered bore and C3 clearance?

The suffix ‘K’ denotes the tapered inner ring bore with a taper ratio of 1:12. This design allows for direct mounting on tapered shaft seats or mounting on cylindrical shafts using a clamping sleeve. The designation C3 stands for increased radial bearing clearance. This clearance is important for tapered seats: when the inner ring is pushed onto the shaft, it expands, thereby reducing the operating clearance. The C3 clearance accommodates this narrowing as well as operational thermal expansion.
