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.
