Founded over a century ago, FLSmidth MAAG Gear just celebrated 100 years of manufacturing gear units for the cement and mineral industries. Our success originates from the toothing design which founder Max Maag developed in 1910. His basic concept is still used in gear manufacturing today. Extensive experience allows us to offer our customers unique modularized and compact solutions combined with the ultimate in gear precision and accuracy.
A century in perspective
Max Maag, a great pioneer in the field of gear technology, founded Maag Zahnräder AG. On April 1, 1913, he moved his company to Hardstrasse 219 in Zurich town. Therefore, 1913 is considered the founding year of Maag-Zahnräder AG. The factory produced hardened, ground gears for a number of industries, such as aviation (Zeppelin), car making, metal working and ship building. It also designed gear-cutting machines and gear grinders.
Around 1930, MAAG went international and founded subsidiaries in France and Italy. Over the next 50 years, the company developed a number of successful gear-measuring and gear-grinding machines. After World War II, the company expanded into the cement and marine industries, producing heavy-duty gear units, turbo gear units and gear pumps.
In the 1980s, the company board defined a new strategy and expanded into a new market by taking over a company that produced powder castings. The machine tool business was closed down and MAAG Gear was founded as an independent company. In the 1990s, FLSmidth purchased MAAG Gear, bringing it into the FLSmidth family.
Since then, FLSmidth MAAG Gear has designed, produced and maintained gears, gear units and drive systems for the cement and minerals industries.
MAAG Gear milestones over the past 100 years
- 1910 - The MAAG™ tooth design, which is still in use today, provides gear manufacturers with an ideal method of influencing tooth shape to improve load bearing and
- 1913 - A gear grinder guided by diamond tracers for precision-shaped gears is used for the car industry. This gear grinder was used during the next 70 years.
- 1939 - The PH-60 was MAAG’s most successful gear-measuring machine. By the time production was phased out in 1981, 1,260 machines had been delivered to customers worldwide. Some are still in use today.
- 1949 - The HSS-360 gear grinder could handle gear diameters up to 3,600 mm and workpieces weighing up to 25 tons, making it the largest gear grinder in the world at that time.
- 1966 - The design of heavy-duty two-stage planetary gear units, called CPUs, for horizontal mills in the cement industry was an extraordinary pioneering achievement. CPUs were more reliable than conventional parallel shaft gear units; 265,000 hours and almost 50 years later, the first two CPUs installed are still running.
- 1983 - MAAG delivered its first WPU two-stage gear unit for a vertical roller mill. The largest WPU gear unit weighs 190 tons and outputs 5,346 kW at a speed of 995/23 rpm.
- 2007 - MAAG introduced its unique concept of a three-stage bevel planetary gear unit WPV with torque split. The torque split enables approximately 25% of the power to be guided directly through the planet shafts of the second stage into the output flange. The three-stage concept was the answer to the ever increasing mill sizes. The biggest MAAG™ WPV weighs 220 tons and outputs almost 8,000 kW.
- 2011 - FLSmidth MAAG Gear launched an entirely new drive concept for vertical mills: MAAG™ CEM™ drive (Central Electric Motor) combines the advantages of proven MAAG™ gear technology with an ingenious motor concept, all in one common housing.
- 2011 - With the acquisition of Darimec, FLSmidth MAAG Gear rounded off the existing range of products and manufacturing skills with girth gears.
- 2012 - Major investments were made at our production facilities in Poland, enabling us to manufacture and test bevel gear sets completely in-house.
A new century dawns
Entering its second century, FLSmidth MAAG Gear continues to develop technology and products while fostering people and careers and driving solutions for the cement and minerals industries. The company is making solid progress, favored by growth in some of the major markets. This will necessitate continuous development of products and strong support from the parent, FLSmidth. FLSmidth MAAG Gear is to become the global technology center for engineered drive solutions in the cement and minerals industries and to be the customers’ preferred full-service provider of sustainable minerals and cement technologies.
