FAG 3211 BD 2RS TVH C3 Double Row Angular Contact Ball Bearing 55x100x33.3

Overview

The FAG 3211 BD 2RS TVH C3 is a double row angular contact ball bearing designed to support combined radial and axial loads acting in both directions. The BD design incorporates an optimized internal geometry with a 30° contact angle, providing higher axial load capacity and increased bearing rigidity. The bearing is fitted with double contact rubber seals (2RS) and C3 internal clearance, making it suitable for demanding industrial applications operating at elevated temperatures and higher rotational speeds.

Industrial Applications

The bearing is widely used in industrial gearboxes, electric motors, pumps, compressors, conveyor systems, machine tools, agricultural machinery, packaging equipment, heavy-duty fans, production machinery and OEM drive systems. It is particularly suitable for applications requiring high stiffness, accurate shaft positioning and the ability to carry axial loads in both directions.

Construction

The 3211 BD 2RS TVH C3 features two rows of precision steel balls running in optimized raceways with a 30° contact angle. The TVH cage, manufactured from glass-fibre reinforced polyamide PA66, provides low weight, excellent wear resistance and smooth ball guidance. Double contact seals retain factory grease while preventing dust, moisture and other contaminants from entering the bearing.

Material

The rings and rolling elements are manufactured from premium through-hardened bearing steel with excellent fatigue strength and wear resistance. The NBR contact seals provide reliable protection against contamination and lubricant loss, while the factory-applied grease ensures long maintenance-free service life under normal operating conditions.

FAQ

What does the BD designation mean?

BD indicates an optimized internal design with a 30° contact angle for increased axial load capacity.

What is the purpose of the TVH cage?

The TVH cage is manufactured from glass fibre reinforced polyamide PA66, providing low weight, excellent wear resistance and smooth ball guidance.

What does C3 internal clearance mean?

C3 provides increased internal clearance to compensate for thermal expansion during operation at higher temperatures or speeds.

Are the 2RS seals contact seals?

Yes. The bearing is equipped with double NBR contact seals that retain grease and prevent contamination.

Can this bearing replace an OEM bearing?

Yes, provided the bearing designation, dimensions and operating specifications match the original equipment requirements.
