Self-Aligning Ball B. FAG 2306 -K-TVH-C3

The FAG 2306 -K-TVH-C3 double-row self-aligning ball bearing compensates for misalignment and, with dimensions of 30 × 72 × 27 mm and a tapered bore, offers flexible mounting options.

The 2306 -K-TVH-C3 self-aligning ball bearing is a double-row rolling bearing with a hollow-spherical outer ring raceway, which automatically compensates for shaft deflection and misalignment. With key dimensions of a 30 mm bore diameter, 72 mm outer diameter and 27 mm width, the bearing primarily accommodates radial loads. Manufactured from standard roller bearing steel 100Cr6 in tolerance class P0 (ABEC 1), it is suitable for bearing arrangements where operational angular misalignments need to be compensated for.

What is the 2306 -K-TVH-C3 self-aligning ball bearing suitable for in operation?

The 2306 -K-TVH-C3 self-aligning ball bearing is primarily used in bearing arrangements with long shafts or flexible housing structures where misalignment or deflection occurs. Thanks to the shared hollow-spherical raceway of both rows of balls in the outer ring, the design compensates for both static and dynamic angular misalignments during operation without unduly increasing friction on the raceways.

What advantages do the tapered bore and C3 clearance offer with this bearing?

The tapered bore with a 1:12 taper allows for precise mounting on stepped shafts or, using a clamping sleeve, on smooth shaft sections. The increased radial clearance (C3) compensates for the reduction in radial clearance that occurs when the inner ring is press-fitted axially onto the tapered bearing seat, and also accommodates thermal expansion within a temperature range of –30 to +120 degrees Celsius.

The integrated polyamide cage (TVH) guides the rolling elements with low vibration and elasticity. As an open bearing, this design requires an external housing seal as well as targeted lubrication with oil or rolling-element grease suitable for your operating conditions.
