Our flexible disc transmission coupling provides a damper between the gearbox and propeller shaft to isolate torsional vibration from the engine and gearbox. It also reduces to shock of forward and reverse gear changes.
Our couplings work in conjunction with the engine mounts by providing the softest element in the shaft assembly to improve performance and provide a sacrificial link that is designed to fail before gearbox damage occurs.
They are designed to cover a large percentage of gearboxes, such as Twin Disc, ZF, Dong-I, Borg Warner, Bukh, Newage, Paragon, Technodrive, Volvo, Yanmar and many more.
Available with DNV-GL “Type Approval” upon request for vessels in survey.
While designed for marine use, these couplings are used in many industrial driveline applications too.
2 Bolt
Two bolt couplings are used on two bolt hole output flanges. Spigots on these couplings can be either male, female, or none, as determined by the flange. Poly Flex couplings are configured to the flanges.

10 Bolt
Ten bolt couplings are used on ten bolt hole output flanges. Spigots can be either male or female, as determined by the flange. Poly Flex couplings are configured to the flanges. Some couplings may need a T bush kits or adaptors are required to clear obstructions, these can be supplied by Poly Flex.
