Yes, most of our mounting systems are designed as failsafe mounts to avoid the engine tearing away from its anchor point, and they will hold the same weight inverted.

Our mounting systems are lightweight and resistant to oil and fuel. They can handle shock upon impact due to a 400% stretch factor in the base material, and the isolation core is designed to control thrust in all directions.

Yes, most of our mounting systems are rebuildable. All parts, including the isolation core, can be replaced when needed without replacing the entire unit.

When finding the appropriate mounting system for a customer’s application, we first determine the suitable mount. This is achievable by determining bolt centre/PCD (E), minimum adjustment height (J), and stud size (F).

Not in every situation. Power and configuration may require four, five, six, or eight-point mounting to achieve the required deflection while still reducing vibration and maintaining durability.

Proper installation of mounting systems is critical for designed life expectancy. It is critical that the top of the engine bed is parallel to the base of the engine bracket across all planes in order to avoid any point loading on the mount base, stud, and core material.

A flexible coupling provides a damper between the gearbox and output flange, helping isolate torsional vibration and reduce shocks from forward and reverse gear changes.

Steel half couplings, coupling spacers, and custom cotton reel adaptors are all CNC machined and designed in our Brisbane facility. They are steel mating components used between the gearbox and output shaft, with or without a flexible coupling.

Most flexible couplings are provided with the hardware necessary to install, meaning no machining or bolting is needed between the existing flanges. They are also dispatched with installation guidelines outlining the process and recommended torque settings for the bolts.

Click here to refer to our transmission cross-reference table. Alternatively, contact us today for help finding a suitable flexible coupling.

To determine a suitable flexible coupling for your application, we will ask for the flange bolt circle diameter/PCD (F), number of bolts and bolt size, and flange index/spigot size and orientation (E).

With an extensive range of over 300 flexible coupling models ranging from 10 horsepower to 2500 horsepower, we cover a large percentage of gearboxes, including but not limited to Twin Disc, ZF, Dong-I, Borg Warner, Bukh, Newage, Paragon, Technodrive, Volvo, and Yanmar. If we don’t have what you need, we can generally custom-design and manufacture a flexible coupling for you.

We use the horsepower, gearbox reduction ratio, and RPM to determine the torque rating of flexible couplings in Nm. We also consider the vessel’s use, either pleasure or commercial.

Poly Flex can supply replacement coupling bolts for most flexible couplings.

A damper plate is a fundamental component that keeps machinery working efficiently by attaching to the flywheel with bolts and works by dampening vibrations from the drive train.

Poly Flex damper plates are designed to reduce gear noise and spline wear and isolate torsional vibrations at lower speeds. This is achieved by the damper’s various hardnesses between the two drive plates, varying from 80 to 1000 Nm—engines up to 700HP.

The flexible element is made from a type of polyurethane elastomer that has good heat qualities and isn’t affected by salt water, diesel, or lubrication oil. It is situated between two drive plates.

Drive plates and all other steel components are cobalt zinc coated to inhibit rust for extended life.

Poly Flex damper drive plates are designed to be failsafe and maintain the drive if the flexible element fails.

Poly Flex currently offers five spline types for purchase, including two 10-tooth varieties, a 26-tooth, an 18-tooth, and a 22-tooth.

Flywheel damper plates reduce gear noise and spline wear and isolate torsional vibrations at lower speeds.
