Self-Aligning Ball B. FAG 2212 -TVH

The FAG 2212-TVH self-aligning ball bearing, with a 60 mm bore and a polyamide cage, provides precise angular compensation for shaft deflection in mechanical engineering applications.

The 2212-TVH self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel 100Cr6 with a 60 mm cylindrical bore. Thanks to the shared hollow-spherical raceway in the outer ring, this design automatically compensates for misalignment and alignment errors between the shaft and housing. As an open design without an integrated seal, the bearing operates with standard radial clearance and is suitable for operating temperatures ranging from –30 to +120 degrees Celsius. The integrated polyamide cage guides the rolling elements with low vibration.

What is the 2212-TVH self-aligning ball bearing suitable for in operation?

This design is particularly useful in applications where shaft deflection or misalignment between the bearing seats occurs. The spherical outer ring raceway accommodates misalignment without restricting the rotational movement of the two rows of balls. This prevents edge loading and promotes even load distribution. As this is an open bearing, the lubricant can be applied directly into the assembly and adapted to the operating conditions.

What are the special features of the polyamide cage in the 2212-TVH?

The suffix ‘TVH’ denotes a polyamide cage. This material reduces the cage’s own weight and ensures quiet and smooth running of the rolling elements. When designing the bearing mounting, the permissible temperature range of -30 to +120 degrees Celsius must be taken into account. As the bearing is designed without integrated sealing washers, the bearing mounting in the housing must be protected against dirt particles and moisture to prevent premature wear.
