Self-Aligning Ball B. FAG 2205 -K-TVH-C3

The FAG double-row self-aligning ball bearing 2205 -K-TVH-C3 (25x52x18 mm) features a tapered bore and C3 clearance, and automatically compensates for misalignment.

This double-row roller bearing, made from standard roller bearing steel (100Cr6), automatically compensates for misalignment and shaft deflection during operation. As an open self-aligning ball bearing 2205 -K-TVH-C3, it has a common hollow-spherical raceway in the outer ring. The integrated polyamide cage guides the rolling elements with low rolling resistance and is suitable for operating temperatures ranging from -30 to +120 degrees. This version is manufactured to the standardised tolerance class P0/PN or ABEC 1.

In which installation situations does the 2205 -K-TVH-C3 self-aligning ball bearing prove its worth?

The bearing is primarily used in applications involving long shafts or flexible housing designs. If operational misalignments occur between the inner and outer rings, the bearing prevents internal stresses. The design primarily accommodates radial loads, but can also withstand moderate axial forces in both directions. As no seals are integrated, sealing is provided by the surrounding housing structure.

What is the function of the tapered bore and the C3 clearance?

The designation ‘K’ stands for a tapered bore with a taper ratio of 1:12. This design allows mounting on cylindrical shafts using a collet or directly onto a tapered shaft seat. The increased radial bearing clearance (C3) compensates for the bearing play, which inevitably decreases when the inner ring is pushed on axially. At the same time, the C3 classification provides a margin of safety against temperature differences between the inner and outer rings caused by operating conditions.
