Self-Aligning Ball B. FAG 1206 -TVH-C3

The FAG 1206 -TVH-C3 self-aligning ball bearing, with dimensions of 30x62x16 mm, enables automatic angular misalignment compensation and features an increased C3 radial clearance.

The double-row 1206 -TVH-C3 self-aligning ball bearing from FAG primarily accommodates radial loads and automatically compensates for misalignment and shaft deflection. Manufactured from standard rolling-bearing steel 100Cr6 in tolerance class P0/PN (ABEC 1), this open rolling bearing is suitable for operating temperatures ranging from –30 to +120 degrees. The shared hollow-spherical raceway in the outer ring guides the two rows of balls with low friction and ensures smooth running even under static or dynamic misalignment.

Under what operating conditions does the 1206 -TVH-C3 self-aligning ball bearing compensate for misalignment?

Designs with larger spans between bearing locations tend to develop misalignments between the inner and outer rings during operation. The 1206 -TVH-C3 self-aligning ball bearing compensates for such installation inaccuracies or elastic deflections directly within the bearing arrangement, without causing impermissible edge stresses. As an open bearing without integrated seals, this design allows for lubrication tailored to requirements directly via the housing system.

What is the function of the TVH polyamide cage and the C3 bearing clearance?

The suffix ‘TVH’ denotes a polyamide cage, which ensures quiet running and low rotating masses. The radial bearing clearance ‘C3’ indicates increased bearing clearance compared to the standard version. This additional clearance compensates for interference fits on the shaft and for thermal expansion when a temperature gradient occurs between the inner and outer rings. When designing the bearing mounting, an external seal must be provided to protect the rolling bearing from foreign particles.
