Self-Aligning Ball B. FAG 2308 -K-TVH-C3

The FAG 2308 -K-TVH-C3 self-aligning ball bearing, with a 40 mm tapered bore and C3 clearance, compensates for misalignment and shaft deflection during operation.

The FAG 2308 -K-TVH-C3 self-aligning ball bearing is a double-row rolling bearing with a hollow-spherical outer ring raceway for industrial applications. Thanks to this design, the bearing automatically compensates for shaft misalignment or alignment errors. With dimensions of 40 mm bore diameter, 90 mm outer diameter and 33 mm width, the component is made from standard 100Cr6 rolling bearing steel. An integrated polyamide cage guides the rolling elements with low vibration and covers a temperature range from –30 to +120 degrees.

When is the 2308 -K-TVH-C3 self-aligning ball bearing used?

This double-row self-aligning ball bearing is used when shaft deflection or misalignment occurs between housing bores. Such angular deviations tend to occur particularly in long shaft guides or flexible frame constructions. As the open design features no integrated grinding or cover discs, it is primarily installed in protected environments or in housings with external seals. The geometry accommodates angular misalignment without causing damaging edge pressure on the raceways.

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

The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12, which allows for mounting on clamping or withdrawal sleeves. The designation ‘TVH’ stands for a flexible cage made of polyamide. The designation C3 indicates an increased radial bearing clearance. This additional clearance prevents the rolling elements from jamming if interference fits on the shaft cause the inner ring to expand, or if operational temperature differences arise between the inner and outer rings.
