Free-wheel right is standard for rear-mounted power take-off! Shafts with a friction/freewheel clutch maintain a high torque when slipping. Suitable as a starting clutch during acceleration of large masses and limits short time torque peaks during operations and are used as protection against heavy rotating attachments where torque of there own mass can cause damage to the driving transmission. Stated values apply at 10° angular deflection on the wide-angle joint and 5° angular deflection on the standard joint and a lifetime of 1000 hours.
