Patented Heavy Duty Cushion Coupling providing limited predetermined rotational travel whilst carrying a MASSIVE 2000 NM (1500 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.
Replaces light duty rubber couplings.
Radial springs absorb shocks with radial travel limited to 1/2 " (12mm) to suit timed shaft applications (Rotary cutters with overlapping timed blades).
