It currently has over 300 couplings for engine models ranging from 10 horsepower to 2500 horsepower, allowing quick response to customer requirements. Targeting excellence in product design and development allows Poly Flex to constantly expand its range. All products are proudly designed and manufactured in-house, making Poly Flex a highly trusted coupling manufacturer.
Why Are Poly Flex Couplings Suitable For Use In Light Engines?
Poly Flex flexible couplings for engines are moulded from engineering heat cured polymer alloys meeting the highest standards. Poly Flex uses various hardness polymer alloys to achieve the most desirable vibration control balanced with durability, including:
- 80A durometer (green) light duty
- 90A durometer (red) medium duty
- 95A durometer (light blue) heavy duty
- 80D durometer (dark blue) super heavy duty
This allows Poly Flex to tailor a flexible coupling to customer requirements based on factors such as:
- Vessel construction
- Engine/Gearbox make and model
- Engine horsepower
- Engine RPM
- Gearbox reduction ratio
- Engine/Gearbox configuration
- Vessel use
Important Design Factors In Couplings For Engines.
All flexible couplings for engines are tested to determine the torque rating in Newton-Metre, allowing Poly Flex to supply an appropriate hardness flexible coupling to suit any application. Poly Flex design all flexible couplings to be rated at 50%-70% maximum allowable static torque to allow for dynamic loads. To ensure maximum strength, durability and performance, all flexible couplings for engines are dispatched with installation guidelines outlining the process and recommended torque settings for the bolts. Poly Flex flexible couplings are provided with all hardware necessary to install, meaning no further machining or bolting is needed between the existing flanges.
How Do Couplings For Engines Enhance Performance?
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. With an extensive range of flexible couplings for engines, Poly Flex covers a large percentage of gearboxes, including but not limited to Twin Disc, ZF, Dong-I, Borg Warner, Bukh, Newage, Paragon, Technodrive, Volvo, and Yanmar.
Poly Flex manufactures a wide range of flexible couplings for engines that are continuously expanding. Poly Flex is a leading manufacturer and supplier located in Brisbane that has been supplying Australian-made flexible couplings worldwide.
