Description

Internal Freewheels FXN are sprag freewheels without bearing support and with sprag lift-off X.

The sprag lift-off X ensures a wear-free freewheeling operation when the inner ring rotates at high speed.

The outer ring is pressed into the customer housing. This makes compact, space-saving fitting solutions possible.

Nominal torques up to 20 500 Nm. The torque is transmitted on the outer ring by press fit.

Bores up to 130 mm. A multitude of standardized bore diameters are available with short delivery times.
