Self-Aligning Ball B. FAG 1207 -K-TVH-C3

The FAG 1207 -K-TVH-C3 double-row self-aligning ball bearing automatically compensates for misalignment during operation and has dimensions of 35 × 72 × 17 mm.

This 1207 -K-TVH-C3 self-aligning ball bearing is manufactured by FAG and is made from standard rolling-element bearing steel (100Cr6). As a double-row bearing, it features a spherical outer ring raceway, allowing the inner ring and the ball cages to settle elastically. With a bore of 35 mm, an outer diameter of 72 mm and a width of 17 mm, this open roller bearing is suitable for applications where misalignment or shaft deflection occur during operation.

In which bearing arrangements is the 1207 -K-TVH-C3 self-aligning ball bearing used?

The bearing is designed for rotating shafts and bearing arrangements in general mechanical engineering. The spherical raceway automatically compensates for design-related misalignments between the inner and outer rings during operation. This enables the component to reduce any edge loads that may occur. The open bearing allows lubrication with oil or grease via the machine housing, suitable for a temperature range of -30 to +120 degrees.

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

The suffix ‘K’ refers to the tapered bore with a taper ratio of 1:12. This design allows for fixed mounting on tapered shaft seats or, using a locking sleeve, on smooth cylindrical shafts. Sliding the inner ring onto the taper reduces the radial bearing clearance. The factory-set increased bearing clearance class C3 ensures that sufficient operating clearance remains after assembly and when the bearing heats up during operation. The polyamide cage (TVH) guides the rows of balls quietly.
