We are also the Australian Agent and Distribution partner for iwis antriebssysteme, Germany. The World’s Leader of: “Precision Chain Drive Systems ” Specialty Transmission & Conveyor Chains, for Original Equipment Specifications.  iwis, as a manufacturer of precision chain systems, takes such critical factors as length tolerances, fatigue strength and varying temperature ranges into account in order to provide individual, application-specific customised solutions. Chains are modular systems made up of a wide variety of characteristics such as surface treatment, materials and production processes, so iwis can always create the right product for your application in terms of corrosion resistance and maintenance-free operation, too: a tailor-made solution.


UMS Transmissions supplies everything from high-quality chain and belt drive systems for automotive camshafts, fuel injection pumps, balance shafts, oil pumps and sub-assemblies to a comprehensive range of high-quality precision chains for a variety of industries. UMS Australia can provide a  wide selection of customised iwis chains manufactured to suit individual customer requirements and a comprehensive range of chain/related accessories. We aim to contribute to your success by supplying technically perfect, top-quality products.

The five main iwis brands cover the entire range of innovative drive solutions. Different performance categories ensure that iwis can provide the right solution for almost every drive engineering application.

iwis Roller chains

iwis offer a comprehensive range of roller chains in accordance with DIN and ANSI standards, as well as numerous special chains for a variety of uses. Choose from a wide variety of iwis high-performance roller chain types: e.g. roller chains with straight side plates, roller chains heavy versions, double pitch type, corrosion resistant and maintenace-free chain, stainless steel chains or side bow chains. Besides conventional roller chains of all types and sizes, roller chains with attachments and double pitch roller chains, we also offer special chains such as grip chains, accumulation chains, elastomeric profile chains, leaf chains, bushed conveyor chains, hollow pin chains and many other models. Maintenance-free or corrosion-proof chains are available for special applications. Their pin oven chains and tube conveyor chains enable a wide range of solutions for the efficient production and optimum conveying of cans and tubes. Find out more about our product brands such as MEGAlife or b.dry. iwis Roller chains are characterised by an above-average service life due to excellent wear resistance, high consistency, matchless precision and a considerably higher breaking strength and fatigue strength than required by DIN/ ISO standard. All iwis chains are pre-stretched and are provided with a highly efficient initial lubrication. iwis SL series chains (Super Longlife) have pins with an extremely hard surface. This special design shows outstanding characteristics: Highest wear resistance, a prolonged service life, high breaking and fatigue strength, low susceptibility to deficient operational lubrication, corrosion and frictional corrosion in the chain links.

High quality is based on each individual part being technically perfect

Use of high-grade heat-treatable steels which are made exclusively for iwis to their material analysis, tolerance and surface quality.

iwis Conveyor Chains

Conveyor chains are used to transport unit loads and bulk goods. iwis offers a wide range of conveyor chains for a variety of purposes. Bush conveyor chains are often used for conveying tasks involving long distances and relatively low speeds. Rotary chains for heavy-duty applications feature cranked links for greater elasticity and improved cushioning of violent impacts. Most conveyor chains used in industry are not standard versions, and iwis delivers conveyor chains that are custom-built to individual customer specifications. iwis conveyor chains can especially be matched with the demands of customer applications. iwis does not only supply the customer with a wide range of special straight attachments and bent attachment plates, but the Technical Service Team offers solutions for individual customer demands and designs custom-made products. iwis conveyor chains offer the user the benefits of parallel and synchronous running, extremely precise positioning, quiet running and a significantly higher breaking resistance than the norm. Also available: conveyor chains with extended bearing pins, conveyor chains with U-shaped attachments and multiple strand connecting links.
