Poly Flex Group Pty Ltd is an Australian company and since commencing in 1981 we have continued to expand both in product range and areas of export. Poly Flex manufactures Engine Mounting Systems, Flexible Disc Couplings & Steel Shaft Couplings which are available with DNV Type Approval. Det Norske Veritas (DNV) is a Norwegian based classification society, a respected leader of manufacturing procedures and standards that is accepted by class approval societies and approving bodies worldwide.
Poly Flex Flexible Disc Couplings are designed to act as a dampener between gearbox and driveshaft while still maintaining strength, rigidity and performance. We have over 200 models (10 – 2500 HP) and are continually expanding our range to meet your requirements. All our couplings are tested and most are available with DNV Type Approval. Our couplings are machined on specially designed jigs to mimic the gearbox flange so they are machined as if they were bolted to the back of your gearbox before fitting.
Resilient mountings are necessary to reduce the transmission of vibration developed from an engine to the vessel or equipment. Poly Flex have over 1600 models (10 – 2000 Kg) of Engine Mount Systems that cater for Marine, Defence, Agricultural, Mining, Industrial & Commercial applications. Our products are moulded from heat cured polymer alloys which are long lasting and oil/fuel resistant. We have a selection of core hardnesses to meet every job requirement in the industry whether it be a light or heavy duty application.
Our Steel Half Couplings are used to join the Flexible Disc Coupling to the propeller shaft and like all our componentry, are CNC machined and engineered to a high standard. All metal components are plated in Cobalt Zinc (SA5) which has very good wear and corrosion resistance. We are proud to say that all products are designed & manufactured in house. We also have the ability to machine and supply custom steel couplings, spacers and adaptors on request.
Poly Flex’s ability to respond quickly to our customers requirements together with our extensive product range has created the worldwide distribution network it has today. We target excellence in product design and development in which we are continually expanding our product range and growing our company. We look forward to giving you ‘the customer’, a solution for your application. Contact us today to find out how we can assist you in taking out vibration for your installation while maintaining rigidity and strength.
Both engine and drive line vibration have been an issue in the marine industry for a long time. At Poly Flex our goal is to improve this dramatically even to the point were it becomes non existent. We have developed a range of high quality engine and machinery mounts and flexible drive couplings, tailored to meet the demands of today’s requirements.
Our Poly Flex mounting systems are designed as true marine propolsion engine mounts with sufficient vertical deflection to obtain proven vibration isolation. They have controlled minimum thrust and lateral deflection under propolsion load and inertia due to sea conditions. They are designed to have a failsafe that in the event of a capsize the engine will not break away from it’s bearers. Moulded components are manufactured from Polénite™ a special range of engineering heat cured polymer alloys.
Our mounts are also suited to the mining, defence, industrial,commercial, agricultural and automotive industries. We also manufacture mounts for instrumentation.
Flexible Drive Couplings
Poly Flex flexible disc transmission couplings provide a damper between the gearbox and propeller shaft to isolate torsional vibration from the engine and gearbox. It also reduces the 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. All metal components are plated in SA5 Cobalt Zinc for maximum corrosion resistance and durability.
The moulded components are manufactured from Polénite™ a special range of engineering heat cured polymer alloys. All our components are proudly designed, engineered and manufactured by Poly Flex.
Steel Shaft Couplings
Our steel half couplings & spacers are manufactured from CS1040 grade bright steel and machined to high precision in our CNC turning centre. They are machined in two stages where extreme care is taken to ensure there is no more than .001” (.025mm) runout. We aim for a high quality finish and tolerance. The next stage of the process is to give our half couplings a coating to resist natures elements, which causes rust and corrosion. As we do with all our steel components, they are treated with a SA5 cobalt zinc, process which has far better properties that standard passivated zinc and therefore giving a much longer lifespan. We also manufacture and supply custom half couplings, spacers cotton reels and adaptor plates.
