B8507

Cushion / Freewheel Coupling for Hydraulic Motor 1 3/8" Anticlockwise - B8507

Spring Freewheel Coupling Assembly for Hydraulic Motor.

Standard 1 3/8" x 6 spline female - female.

Standard Anti-clockwise rotation.

Unique design for hydraulically driven rotary cutters.

Allows hydraulic motor to run at ideal 500 / 600 rpm range.

Allows drive through standard agricultural gearbox. 1:1.47 OR 1:1.93 Ratio.

Prevents transmission impact failures by instantly absorbing a massive 2000 Nm (1500 ft lbs) of torque.

Integral freewheel eliminates transmission failure due to cutter disc inertia during hydraulic valve "STOP" condition.

Dimension "A": 8.46" (215mm),

Dimension "B": 5.5" (140mm),

Rotation: Anti-Clockwise.

Version: 1 3/4" x 20 splines female - female.

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).
