Our ExperienceEvery hour of every day, thousands of our gear drives are operating throughout the

world servicing every industrial, commercial, utilityand transportation application imaginable. We havepaper machine drives operating at InternationalPaper, Union Camp, Boise Cascade, ChampionPaper and Weyerhaeuser. Cooling tower drivesoperating at Florida Power and Light. High speedcompressor drives operating at the Pentagon andthe new Denver International Airport, as well ashigh speed pump drives at Algoma Steel andTennessee Valley Authority. Offshore oil jack-up rigdrives working from the North Sea to the Gulf of

Mexico. Grain elevators running in Vancouver, Minneapolis and Houston. Steel andaluminum mill drives operating at U.S. Steel, National Steel, Reynolds Metals and Alcoa.And we have drives running the chemical plants of DuPont.

We have drives for wind turbines, hydro turbines, conveyors, textile mills, extruders, coalcrushers, elevators, water screens, rail car dumpers, cranes and hoists, briquetting machines,wood debarkers, radar drives and food machinery drives.

Our aeration and sewage treatment drives are found in towns and cities across theUnited States. We have compressor drives working at NASA, the Times SquareCommercial Center in Hong Kong, and thePetronas Twin Towers in Malaysia... turbinedrives operating at Formosa Plastics in Taiwan...and pump drives operating in Cogen facilities inThailand and the Phillipines. We even supplyreactant coolant pump speed increasers fornuclear power plants throughout the UnitedStates and the rest of the world.

We handle the big job and the small. And wehandle them all with the same commitment toquality and service that made the Nuttall name famous.

Our PromiseWe know it takes more than just good gears to make a good company. It takes a

special touch for service, because not every order is standard. We pride ourselves inknowing that we can handle the toughest custom job you have.

We will supply an enclosed gear drive to suit any special requirements you need.We will make a unit to fit your space limitation, a drive with custom shafts, units with

special seals, or extra long bearing life. We willmake vertical and horizontal drives, speedreducers and speed increasers, cast iron andfabricated steel housings. We supply gearmotorswith any type of electric motor, either flangemounted or scoop mounted, constant speed orvariable speed.

Total Drive Source is more than a slogan – weare the only company that specializes in providing

complete packaged assemblies of both mechanical and electrical drive components.We coordinate your entire mechanical and electrical drive package including gear

reducer, and electric motor mounted on a bedplate, with couplings and couplingguards, backstops, creep drives, chains, sprockets, clutches, shoe or disc brakes, orauxiliary lubrication consoles.

You receive it ready to run, not ready to assemble. You will also find our compositedrawings are the best around. You can't get this kind of service from any othercompany in the world.Nuttall Gear is a company with a history of high standardsand performance and we work to keep it that way.

You can count on it.

Innovation and Excellence...The Tradition Continues

Our HistoryThe RD Nuttall Company was founded by Mr. R.D. Nuttall in 1887 with onegear cutter, five men and a combined capital of $500.

From this modest beginning, the company grew and prospered, and over thenext 42 years made numerous contributions to the gear industry. It wasNuttall that developed flexible gearing for transportation applications, forcedfeed lubrication for large industrial enclosed gear drives, and manufacturedthe first integral type gearmotor. And it was Nuttall that made one of the mostsignificant contributions to the field of gear engineering: single helical gears.

In 1928, Westinghouse Electric Corporation purchased the business from Mr.Nuttall. Although the name changed, the original commitment to excellencedid not. Nuttall was known for its innovation and engineering, for it was ourcompany that developed the modern form of the gearmotor which is used bygear manufacturers all over the world today.

February 1983 signified yet another stepforward in Nuttall Gear's history. At thattime, we once again became a privatelyheld corporation, continuing the traditionof leading the industry in technology –such as pioneering the use of ion-nitridingfor heat treating, and the use of our MAAGSP-160, the ultimate machine available toconfirm gear quality.

In 1997, Nuttall Gear was acquired bythe Colfax Corporation and is currently partof the Colfax Power Transmission Group,Engineered Driveline Products.

While there have been corporate changesover the years, some things never change,like your need for durable, dependablegears, and our commitment to excellencein both product and service.
