Self-Aligning Ball B. FAG 2209 -TVH-C3

FAG 2209 -TVH-C3 double-row self-aligning ball bearing with a 45 mm bore, a hollow-spherical outer ring raceway and a slightly increased C3 radial clearance for angularly adjustable mountings.

The FAG 2209 -TVH-C3 self-aligning ball bearing compensates for misalignment between the shaft and housing by design. In this double-row rolling bearing, the rolling elements run on two raceways of the inner ring and in a common spherical outer ring raceway. Manufactured from standard roller bearing steel 100Cr6 with dimensions of 45 x 85 x 23 mm and standard tolerance P0/PN, the component can handle radial loads with shaft deflections in the range from -30 to +120 degrees Celsius.

What is the 2209 -TVH-C3 self-aligning ball bearing suitable for?

Design engineers opt for this design when misalignment or elastic deflection of long shafts is to be expected. The self-aligning bearing dynamically compensates for such angular misalignments during operation without exerting any significant stress on the ball rows. Typical applications include bearing arrangements with long shafts and applications where misalignment is a potential issue. As an open variant, the bearing is designed to be lubricated via the surrounding housing.

What are the advantages of a polyamide cage and C3 clearance?

The polyamide material (cage code TVH) guides the balls with low friction and dampens operating noise. In combination with the increased C3 bearing clearance, smooth running is maintained even when temperature differences occur between the inner and outer rings. Tight fits on the shaft also reduce bearing play once installed, which is why the C3 radial clearance helps to prevent seizing. When fitting open roller bearings, care must always be taken to ensure a clean installation environment and the selection of a suitable lubricant.
