In the case of the standard type, every second sprag has been ­replaced by a cylindrical roller; this freewheel can accept radial forces. Nominal torques up to 2 400 Nm. The torque is transmitted on the outer ring by press fit. Bores up to 80 mm. A multitude of ­standard­ized bore diameters are available with short delivery times.
