Self-Aligning Ball B. FAG 2208 -K-TVH-C3

The FAG double-row self-aligning ball bearing 2208 -K-TVH-C3 (40x80x23 mm) with a tapered bore flexibly compensates for angular misalignment.

The double-row self-aligning ball bearing 2208 -K-TVH-C3 from FAG Rolling Bearings is suitable for withstanding radial loads whilst accommodating shaft misalignment. With a bore of 40 mm, an outer diameter of 80 mm and a width of 23 mm, this rolling bearing offers dimensionally accurate industrial quality in accordance with tolerance class P0. The rolling elements run on two rows of balls in a spherical outer ring raceway, which automatically compensates for misalignment. The component is made from standard roller bearing steel 100Cr6 and is suitable for operating temperatures ranging from -30 to +120 degrees.

What is the 2208 -K-TVH-C3 self-aligning ball bearing suitable for in operation?

This self-aligning ball bearing is primarily used where shaft deflection or misalignment between bearing housings needs to be compensated for. Thanks to the spherical raceway in the outer ring, the design accommodates dynamic misalignments without causing sharp load peaks. In combination with the lightweight polyamide cage, the bearing operates with low vibration and low friction. Typical applications are found in general mechanical and plant engineering on long drive shafts, where housing alignment is subject to tolerances due to the design.

What do the designations K, TVH and C3 mean for your design?

The suffix ‘K’ refers to a tapered bore with a taper ratio of 1:12, which allows the bearing to be mounted on cylindrical shafts using adapter sleeves. The C3 version offers increased radial clearance compared to the standard, which maintains the bearing clearance even in the event of thermal expansion or tight fits. The polyamide cage (TVH) guides the balls quietly and ensures a low moment of inertia. As this is an open bearing, you can select the lubricant and external seal to suit the operating environment.
