Self-Aligning Ball B. FAG 1312 -K-TVH-C3

The FAG 1312 -K-TVH-C3 double-row self-aligning ball bearing, with a 60 mm bore and C3 clearance, offers a tailored solution for bearing mountings with misalignment.

The 1312 -K-TVH-C3 self-aligning ball bearing is a double-row rolling bearing from FAG, manufactured from standard rolling bearing steel 100Cr6 to tolerance class P0/PN or ABEC 1. Thanks to the hollow-spherical outer ring raceway, the component automatically compensates for angular misalignment between the inner and outer rings. In the event of shaft deflection, the bearing compensates for these deviations without generating harmful forced forces. The design is suitable for demanding shaft mountings in accordance with established industry standards.

In which applications does the 1312 -K-TVH-C3 self-aligning ball bearing compensate for misalignment?

This double-row rolling bearing is suitable for designs where elastic shaft deflection or misalignment occurs between housing mountings. The two rows of balls primarily absorb radial loads and support rotating shafts. Due to its permissible temperature range of –30 to +120 degrees, the unit is suitable for general machine shafts and industrial drives. The open design also allows for flexible lubricant selection via the surrounding machine housing.

What functional properties do the tapered bore and polyamide cage offer?

The suffix ‘K’ refers to the tapered bore with a taper ratio of 1:12, which allows the bearing to be mounted directly onto tapered shaft seats or using a shrink sleeve. The polyamide cage (TVH) guides the rolling elements with low friction and dampens vibrations. Thanks to the slightly increased radial clearance (C3), the required operating clearance is maintained even after press-fitting onto the taper and during thermal expansion in operation.
