Self-Aligning Ball B. FAG 2208 -2RS-TVH

The 2208 -2RS-TVH double-row self-aligning ball bearing, measuring 40x80x23 mm, compensates for misalignment and, thanks to its lip seals, protects against the ingress of dirt.

The 2208 -2RS-TVH self-aligning ball bearing from FAG Rolling Bearings is a double-row bearing made from standard rolling bearing steel (100Cr6) with a common hollow-spherical raceway in the outer ring. This design enables automatic compensation for misalignment between the inner ring and the housing. With dimensions of 40 mm bore, 80 mm outer diameter and 23 mm width, the component primarily accommodates radial loads. The double-sided seal retains the lubricant inside and protects the rolling elements against dirt and moisture.

Under what conditions does the 2208 -2RS-TVH self-aligning ball bearing compensate for misalignment?

The 2208 -2RS-TVH self-aligning ball bearing is used in cases of elastic deflection of the shaft or misalignment between bearing seats. The spherical raceway dynamically compensates for moderate angular misalignment during operation without causing additional edge pressure on the rolling elements. Typical applications can be found in general mechanical engineering as well as in bearing arrangements with longer support spans. As the seals prevent the ingress of particles, the component is also suitable for dusty environments.

What role do the polyamide cage and seal play in bearing selection?

The integrated polyamide cage guides the two rows of balls quietly and reduces the weight of the rotating mass. Together with the seals that seal on both sides, this design covers a temperature range from –30 to +100 degrees Celsius. The bearing features a standard radial clearance and tolerance class P0/PN (ABEC 1). For maintenance personnel, the sealed 2RS design means minimal maintenance, as the factory-applied lubricant remains in place during normal operation.
