Self-Aligning Ball B. FAG 2312 -TVH

The FAG 2312-TVH self-aligning ball bearing, with dimensions of 60 × 130 × 46 mm, provides automatic angular compensation for shaft deflection.

The double-row self-aligning ball bearing 2312-TVH is an open rolling bearing made from standard bearing steel (100Cr6) with a cylindrical bore. Thanks to the common hollow-spherical raceway in the outer ring, this design automatically compensates for misalignment and shaft deflection during operation. With an internal diameter of 60 mm, an external diameter of 130 mm and a width of 46 mm, the bearing primarily accommodates radial forces as well as minor axial forces.

In which installation scenarios does the 2312-TVH self-aligning ball bearing compensate for misalignment?

This double-row bearing is primarily used in designs where there are manufacturing-related misalignments between the housing and the shaft, or where the elastic deflection of long shafts needs to be compensated for. Thanks to the spherical raceway in the outer ring, the rolling elements, together with the inner ring, pivot freely about the centre point without generating additional edge stresses. This ensures smooth running even in the event of slight housing deflection or angular misalignment.

What is the function of the TVH polyamide cage?

The suffix ‘TVH’ denotes a polyamide rolling element cage which guides both rows of balls separately and prevents direct contact between the rolling elements. The material is characterised by its low weight and promotes smooth, low-friction operation. The open bearing without sealing washers is designed for a temperature range of -30 to +120 degrees. Lubrication is supplied via the surrounding housing, although external seals should be fitted to protect against contamination.
