Flexible disc couplings, also known as polyurethane elastomer plates, provide a damper between the gearbox and the output flange, isolating torsional vibration and reducing the shock of forward and reverse gear changes. Our polyurethane elastomer plates work in conjunction with engine mounts and gearbox damper plates to provide the softest element and the driveline assembly. This improves performance and provides a sacrificial link that is designed to fail before gearbox damage occurs.
Poly Flex is a trusted polyurethane elastomer plates supplier in Brisbane. Poly Flex commenced in Australia in 1981 and has continued to expand both in product range and areas of export. Poly Flex manufactures engine mounting systems, polyurethane elastomer plates, and steel shaft couplings, which are all available with DNV Type Approval.
With over 300 polyurethane elastomer plate models ranging from 10 horsepower to 2500 horsepower, we can respond quickly to our customer’s requirements and have created a worldwide distribution network. Poly Flex targets excellence in product design and development, constantly expanding our product range and growing our company with all Poly Flex products proudly designed and manufactured in-house. Our in-house production makes us trusted coupling manufacturers for many years.
Poly Flex is most famous for being polyurethane elastomer plate suppliers for boats; however, our flexible drive plates also service a wide range of different industries. With Poly Flex’s extensive range of polyurethane elastomer plates, they are designed to 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. While our couplings were originally designed for marine use, these couplings are utilised in many industrial driveline applications.
Poly Flex polyurethane elastomer plates are moulded from engineering heat-cured polymer alloys of the highest standards, and all metal components are plated in SA5 Cobalt Zinc, increasing the metal life that normal zinc plating would give by 600%.
All our polyurethane elastomer plates are machined on a purpose-built flange jig and have a maximum runout of 0.002 inch or 0.05mm. Spigots are also machined to a tolerance within +/- 0.002 inch or +/- 0.05mm.
To ensure maximum strength, durability and performance, all polyurethane elastomer plates are dispatched with installation guidelines that outline the process. All installation manuals outline the recommended torque ratings for the bolts used that screw into our couplings. All polyurethane elastomer plates are provided with nuts and bolts ready to install, they require no further machining and bolt between existing shaft flanges.
As your trusted coupling supplier, Brisbane has been home to Poly Flex since 1981. We have a strong focus on providing great customer service and solutions for any application with advanced polymer technology for vibration control. Poly Flex coupling manufacturers are proudly Australian, designing and producing these products locally.For more information regarding our extensive range of polyurethane elastomer plates (flexible disc couplings), including our coupling and transmission cross-reference charts, please click here.
