Self-Aligning Ball B. FAG 2206 -K-TVH-C3

The FAG 2206 -K-TVH-C3 double-row self-aligning ball bearing (30x62x20 mm) compensates for misalignment and features a tapered bore and increased C3 clearance.

The 2206 -K-TVH-C3 self-aligning ball bearing is a double-row rolling bearing with a hollow-spherical outer ring raceway. This design enables the inner ring, together with the ball cages, to automatically compensate for angular misalignment and shaft deflection during operation. Manufactured from 100Cr6 rolling-bearing steel to tolerance class P0 (ABEC 1), this open bearing is suitable for designs with external housing lubrication. The polyamide cage ensures quiet running across a temperature range of -30 to +120 degrees Celsius.

In which installation situations does the 2206 -K-TVH-C3 self-aligning ball bearing prove its worth?

The bearing is primarily used where misalignment occurs between housings or where long shafts deflect elastically under load. Typical applications include designs with separate bearing housings and shaft runs prone to deflection. As it is designed as an open bearing without integrated seals, the lubricant used in the housing can be freely selected. The rolling bearing primarily absorbs radial loads and guides the shaft axially in both directions.

What do ‘tapered bore’ and ‘C3 clearance’ mean for this bearing?

The suffix ‘K’ denotes the tapered bore with a taper ratio of 1:12. This internal profile allows mounting on tapered shaft seats or, using a suitable adapter sleeve, on smooth cylindrical shafts. The operating clearance can be adjusted by sliding the bearing axially along the taper. The slightly increased radial clearance (C3) prevents excessive stress following press-fitting or when the bearing heats up, and contributes to smooth running.
