Self-Aligning Ball B. FAG 2209 -TVH

The FAG 2209-tvh double-row self-aligning ball bearing with a polyamide cage compensates for angular misalignment by design and is suitable for 85 mm housing bores.

The 2209-tvh self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel for applications where misalignment or shaft deflection occurs. Thanks to the shared hollow-spherical raceway in the outer ring, the two rows of balls self-align during operation. This open design with standard radial clearance has an outer diameter of 85 mm and a width of 23 mm, and is mounted directly onto the shaft via the cylindrical bore.

What is the 2209-tvh self-aligning ball bearing suitable for in operation?

Design engineers primarily use this double-row bearing where shafts deflect elastically under load or where housing bores have misalignment caused by manufacturing tolerances. The 2209-tvh self-aligning ball bearing accommodates radial loads and compensates for misalignment between the inner and outer rings without a significant increase in friction. Typical applications are found in general mechanical engineering in bearing arrangements with longer shafts or where two bearing positions must be aligned on separate bearing seats.

What are the advantages of the polyamide cage in this open bearing?

The integrated polyamide cage is characterised by its low weight and favourable sliding properties relative to the rolling elements. As a result, the bearing runs quietly and reduces dynamic stress within the lubricating film. When using this bearing, the permissible temperature range of -30 to +120 °C must be observed. As this is an unsealed bearing, users must incorporate external seals into the housing and adapt the lubricant supply to the operating conditions.
