Known as a premier supplier of parts for the aircraft industry since the 1940s, Sundstrand Corporation is also a leading manufacturer of industrial gear drives, pumps, and compressors. In recent years the company has worked successfully to strengthen its industrial business, lessening its dependence on military and commercial aerospace.

The earliest predecessor to the modern Sundstrand Corporation is the Rockford Tool Company, established in 1905 in the predominately Swedish town of Rockford, Illinois. The company was founded by an inventor and machinist named Levin Faust, who had invented a small metal chuck for carving furniture. Faust invited two young tool makers, Elmer Lutzhoff and Swan Anderson, to become partners in the venture by investing $500 each.

In 1909 the Rockford Tool Company gained a neighbor in its facilities, the Rockford Milling Machine Company. This company, owned by Oscar Sundstrand and his brother-in-law Edwin Cedarleaf, was also rapidly expanding and retained Hugo Olson as its financial advisor. In 1910 the Rockford Milling Machine Company relocated to a larger building where there was more room for the growing business, and the following year, on Olson’s advice, the Rockford Tool Company moved to a building across the street.

In 1914 David Sundstrand, Oscar’s brother and an employee at the Rockford Milling Machine Company, developed a ten-key adding machine. Its sales become so brisk that Sundstrand formed a subsidiary, Sundstrand Adding Machine Company, to accommodate the business. Eventually, the Sund-strands constructed a new four-story building for the adding machine venture a block north of its own facility.

The Rockford Milling Machine Company and the Rockford Tool Company continued on separate but related paths for nearly ten years when, in 1926, Olson suggested that the two companies merge. They were, after all, in related fields of manufacturing, and might otherwise have become competitors. All agreed, and in June 1926, the new firm was incorporated as the Sundstrand Machine Tool Company.

During the early 1930s, Olson saw to it that Sundstrand would follow a course of expansion through diversification. The first step in this direction was to improve the manufacturing processes of the company’s products. While many of Sundstrand’s tools and other implements had been carefully made by hand, this method proved increasingly inadequate for the exact tolerances that were required for precision machine tools. In 1932 Sundstrand machinists began to experiment with hydraulic tools that enabled workers to hold pieces of metal more securely so they could be more accurately fashioned into tools. By 1934, all the company’s hand-crank machinery had been replaced with hydraulic devices. Also that year, Sundstrand introduced a line of hydraulic pumps for residential oil-burning furnaces. Soon thereafter, the company introduced a complete line of hydraulic pumps, fluid motors, and hydraulic transmission systems.

As a result of the Great Depression, product orders at Sundstrand dwindled, and the company was forced to drastically scale back production and lay off workers. As investment values crashed, Olson announced in Sundstrand’s 1932 annual report that “directors deemed it advisable to change the stated value per share from $17.90 to $5.00 per share.” However, on the strength of its tools and hydraulics businesses, and its place as a supplier to primary industries, Sundstrand steadily recovered from the Depression. By 1933, the company was restored to profitability and well on the way to satisfying its financial obligations. On February 8, 1936, Olson announced that the company “has no bank loans, unfunded debt, and no past due liabilities.”

That year, Sundstrand acquired the American Broach and Machine Company, a tool manufacturer based in Ann Arbor, Michigan. Between 1937 and 1939, Sundstrand introduced several new machine tools, including a successful hydraulic “Rigidmill” and automatic lathe. Furthermore, in 1939, with most of American industry on the road to recovery, demand for feed pumps, fuel units, and controls was high. Sundstrand’s fuel unit sales alone quadrupled between 1938 and 1939. By 1940, sales were up to $6.4 million.

A major product of this research and development effort was the application of hydraulics to aviation engineering. In the final year of the war, and for the remainder of the 1940s, Sundstrand developed several important new products, including a variable displacement hydraulic transmission for aircraft engines. This Constant Speed Drive (CSD) was first applied on the Air Force’s ten-engine B-36 bomber, to convert the aircraft’s variable engine speed to a constant rate of rotation for driving electric generators. The company’s newfound success in aircraft products necessitated a new Sundstrand aviation division. This was a highly profitable line, as aviation and nuclear weaponry became the nation’s premier instruments of defense against the threat of Soviet attack. In 1949 Hugo Olson died and his son, Bruce F. Olson, assumed the presidency of Sundstrand.

The 1950s were a decade of expansion for Sundstrand. In 1950, with continued strength in machine tools, pumps and aviation products, Sundstrand marked sales of $16.4 million. As Sundstrand’s product line gained an international clientele, Bruce Olson moved to establish the Sundstrand International Corporation, headquartered in France, in 1952. That same year the company established an oil pump manufacturing facility in Sweden. In 1954 the company established a separate hydraulics division, with its own manufacturing facility in Rockford. Two years later, Sundstrand opened a plant in Denver, employing 400 people in the manufacture of CSDs for both military and commercial jet aircraft markets. Furthermore, in 1957, Sundstrand built a consolidated machine tool manufacturing facility in Belvidere, Illinois. That year, with sales topping $77.5 million, the Sundstrand Machine Tool Company was listed on the New York Stock Exchange. Two years later, shareholders voted in favor of a proposal to change the name of the company to the Sundstrand Corporation.

During the early 1960s, a team from the company’s Hydraulics division experimented with applications of CSD technology on off-highway equipment. To commercialize these applications, the company merged this team with another from its Aviation division to form a fourth operating unit, Hydro-Transmission. In 1965 Sundstrand built a separate facility in LaSalle, Illinois, especially for this division, and began supplying hydrostatic transmission components to the automotive industry. This operation was subsequently expanded to include yet another facility, located in Ames, Iowa.

In 1967 Sundstrand began an aggressive internal and external product and market diversification campaign. Internally, the company created a fifth division—Sundstrand Fluid Handling, established in 1970—to adapt certain Aviation Division products for use in other industries. The division’s first product was a jet engine water injection pump, altered to pump other liquids. This new pump, called Sundyne, found many applications, particularly in the petrochemical industry. The company also established centers to produce new axial gear differentials, integrated drive generators, data recorders, cartridge pneumatic starters, and milling machinery.

The 1970s marked a turning point for Sundstrand. After the diversification and acquisition binge of the late 1960s, the company spent much of the next decade consolidating its growth. Rather than increasing sales volume, Sundstrand concentrated instead on raising earnings, shoring up its balance sheet, and maximizing market penetration. Along these lines, Sundstrand divested itself of three non-strategic divisions, selling off its machine tool operation in 1977 and its Sundstrand Compressors unit and fuel oil pump business in 1979.

In 1987 Sundstrand formed a joint venture with Sauer Getriebe AG, combining the hydraulic power systems operations of both companies. While the venture operated 12 manufacturing facilities worldwide, it failed to meet Sundstrand’s goals, leading the company to dissolve its interest in the business in 1989

In January 1990, Sundstrand acquired the French company Maco-Meudon, a supplier of pneumatic contractor tools to Sullair, and a year later, the company purchased the Milton Roy Company, a manufacturer of metering pumps and analytical instruments. While 1991 revenues increased four percent, to $1.67 billion, earnings dropped five percent, to $108.8 million. CEO Harry Stonecipher—who replaced O’Hare as chairman in 1991—introduced centralized financial controls and began to streamline operations. He trimmed the payroll by 22 percent, to less than 13,000 employees, sold off peripheral businesses, and strengthened Sundstrand’s core businesses through acquisitions.

These included the Electrical Systems Division of Westing-house, a producer of electrical power systems for aircraft. Purchased for $125 million, the unit generated $100 million in annual revenue, and was expected to increase sales at Sundstrand’s electric power division by 20 percent. With cuts in defense spending rapidly shrinking Sundstrand’s military sales, from 22 percent of total revenues in 1991 to 15 percent in 1992, Stonecipher looked to the commercial airline industry and sales from Sunstrand’s industrial division to make up the difference. The industrial division, which manufactured pumps, gears, and compressors, accounted for approximately 40 percent of Sundstrand’s revenues.

Stonecipher continued his efforts to sharpen Sundstrand’s focus, manage the decrease in military spending, and control production costs. In November 1993 the company announced the sale of Sundstrand Data Control to AlliedSignal, for $195 million; the following year, Sundstrand purchased two small pump manufacturing companies, HMD Group Ltd and Kontro Company. In September 1994 the highly regarded Stonecipher resigned suddenly to head McDonnell Douglas. Don O’Hare, who came out of retirement to guide the company while searching for a successor, stated, “I clearly anticipate that Sundstrand’s successful track record will not be interrupted while we identify a new chief executive officer for the next decade.” Nevertheless, Sundstrand’s stock jumped on speculation that the company was a takeover target.
