Self-Aligning Ball B. FAG 2204 -TVH

The FAG 2204-TVH self-aligning ball bearing, measuring 20 × 47 × 18 mm, compensates for misalignment and houses two rows of balls in a lightweight polyamide cage.

The 2204-TVH self-aligning ball bearing is a double-row rolling bearing made from standard 100Cr6 bearing steel with a cylindrical bore. The shared spherical raceway in the outer ring enables the compensation of both static and dynamic angular misalignments between the shaft and housing. The manufacturer, FAG, fits this version with a polyamide cage. As an open component without integrated sealing washers, the bearing can be integrated directly into existing lubrication circuits or supplied with grease as required.

What is the 2204-TVH self-aligning ball bearing suitable for in operation?

Design engineers turn to this bearing when shaft deflection or misalignment between the bearing seats cannot be completely avoided. Typical applications include bearing arrangements with long shafts or flexible housing designs. Due to the oscillating movement of the rows of balls within the outer ring, no harmful edge pressures occur, even with slight misalignments. The component primarily absorbs radial loads but, given the appropriate geometry, can also withstand moderate axial forces in both directions.

What distinguishes the TVH polyamide cage in this self-aligning ball bearing?

The suffix ‘TVH’ denotes a polyamide cage that guides the rolling elements with low vibration. Compared to versions made of sheet steel or brass, this material reduces the weight of the rotating components and lowers operating noise. When designing the bearing, the permissible temperature range of -30 to +120 degrees must be taken into account. As an open variant, the bearing requires a sealed environment provided by the customer as well as a suitable supply of lubricant.
