Self-Aligning Ball B. FAG 11206 -TVH

The 11206-TVH self-aligning ball bearing from FAG Rolling Bearings, measuring 30 x 62 x 48 mm and featuring an inner ring widened on both sides, provides a secure fit even when misaligned.

The 11206-TVH self-aligning ball bearing is a double-row rolling bearing made from standard 100Cr6 bearing steel with a standard radial clearance. Thanks to the hollow-spherical outer ring raceway, this bearing automatically compensates for misalignment and shaft deflection during operation. FAG manufactures this version with a lightweight polyamide cage and without integrated sealing washers. Design engineers specifically use this variant for shaft mountings where axial fixation and angular adjustability are required.

What is the 11206-TVH self-aligning ball bearing suitable for in operation?

The bearing is used when housing seats are not precisely aligned due to manufacturing tolerances, or when long shafts deflect elastically under load. Thanks to the two rows of balls, the assembly absorbs radial loads whilst simultaneously compensating for both static and dynamic angular misalignment. The permissible temperature range is from –30 to +120 degrees. The open component is supplied with grease or lubricating oil directly via the surrounding machine housing, which promotes low-friction movement of the rolling elements.

What are the advantages of the inner ring widened on both sides?

The inner ring, which is widened on both sides, increases the contact area on the shaft with a 30 mm bore diameter. This design facilitates mounting, reduces the risk of the bearing tilting in its seat and simplifies axial securing during repairs or new installations. With a tolerance class of P0/PN or ABEC 1, this design meets standard industrial accuracy requirements. The integrated polyamide cage guides the balls evenly and reduces the total rotating mass of the bearing assembly.
