H/Duty Torque Cushion Couplings

HEAVY DUTY BARE-Co PATENT CUSHION COUPLINGS

Patented Heavy Duty Cushion Coupling providing limited predetermined rotational travel whilst carrying a MASSIVE 1900 NM (1400 ft/lbs) of Torque. Danish Super Valve Spring Quality drive springs combined with 1 piece heat treated Drive and Driven Plates provide ultimate reliability. Designed for LARGE Multihead Cutters with Timed Blades which preclude the use of safety slip clutches. *Without the Bare-Co® Heavy Duty Cushion Coupling, these machines can suffer outer gearbox coupling & shaft failures* due to the flywheel effect of associated cutter disks being combined with tractor PTO torque.
