Self-Aligning Ball B. FAG 2311 -K-TVH-C3

The FAG 2311 -K-TVH-C3 double-row self-aligning ball bearing (55x120x43 mm) compensates for misalignment and, thanks to its C3 radial clearance, ensures reliable operation under thermal conditions.

The 2311 -K-TVH-C3 self-aligning ball bearing from FAG Rolling Bearings is an open, double-row rolling bearing made from standard rolling bearing steel (100Cr6) with a hollow-spherical outer ring raceway. This design automatically compensates for misalignment and shaft deflection during operation. With a tapered bore of 55 mm, an outer diameter of 120 mm and a width of 43 mm, this bearing is suitable for demanding applications in mechanical and plant engineering under varying operating conditions.

What is the 2311 -K-TVH-C3 self-aligning ball bearing suitable for?

The use of this self-aligning ball bearing is particularly recommended where misalignment occurs between the inner and outer rings, or where shafts deflect elastically under load. Typical applications include bearing arrangements with long shafts or designs with static and dynamic misalignments. The open design allows for flexible lubrication with grease or oil directly via the surrounding housing. Thanks to its permissible temperature range of –30 to +120 degrees, the bearing performs well in industrial environments subject to standard thermal loads.

What do the designations K, TVH and C3 mean?

The designation ‘K’ indicates a tapered bore with a taper ratio of 1:12, which allows mounting on shrink sleeves or pull-off sleeves. The abbreviation ‘TVH’ refers to a polyamide cage, which ensures smooth running and low moving mass. The slightly increased radial clearance (C3) reduces the risk of the rolling elements becoming jammed if the radial clearance shrinks due to a tight fit or operational heating. The component complies with tolerance class P0/PN or ABEC 1.
