The historical perspective
of MRC
MRC is the outgrowth of three of America’s oldest bearing companies—Standard Roller Bearing Company, Gurney Ball Bearing Com- pany, and Strom Bearing Company.
The Standard Roller Bearing Company
was formed when a Philadelphia industrialist, S. S. Eveland, merged the Ball Bearing Com- pany of Boston with seven other major ball bearing and ball-making equipment manu- facturers. The company used the SRB Dia- mond trademark. SRB made many contribu- tions to the advancement of anti-friction bearings; most notably, the development of 52100 steel, a high carbon, high chrome alloy steel that greatly improved bearing life.
In 1902, Frederick W. Gurney started the manufacture of ball bearing machinery in Jamestown, New York. He originated the Gurney “radial-thrust angular-contact” bearing (today’s 7000 Series) in 1905, and the Gurney “radial-Type R” bearing (same designation today) in 1909. Gurney also developed duplex bearings—a matched pair of counterbored bearings—which were a major contribution to the accuracy of high speed machine tool spindles.
Stephen Snyder began manufacturing filling slot radial ball bearings in a small Chicago shop in 1908. His business was in-

corporated in 1909 as the U.S. Ball Bearing Manufacturing Company. Axel Strom became sole owner and changed the name to Strom Ball Bearing Manufacturing Company. The company established itself as a major supplier of precision ball bearings to the automotive and machinery industries. A major innovation by Strom was engineering service, provided to customers, “to aid in proper choice of ball bearings, their use, and guidance for mount- ing and maintenance.”
Prior to World War I, Albert F. Rockwell, one of two brothers who founded New De- parture Company, formed the Rockwell- Drake Corporation to manufacture ball bear- ings in Plainville, Connecticut. During the war, Rockwell combined Rockwell-Drake Corpora- tion with several other corporations including the Standard Roller Bearing Company of Philadelphia.
After World War I, some of the manufac- turing units were liquidated and the company was reorganized as Standard Steel and Bearing, Inc., Division of Marlin Rockwell Corporation. In 1923, the bearing manufac- turing plants were consolidated at Plainville, Connecticut. The following year, Gurney Ball Bearing Company merged with Marlin Rock- well Corporation. MRC® purchased Strom Ball Bearing Manufacturing Corporation in 1925 and its assets were moved to Jamestown, New York, in 1931.
The manufacturing experience, technical background, and managerial skills of these antecedent companies provided Marlin Rock- well with a firm base out of which to develop and grow. In 1953, a new state-of-the-art plant was built at Falconer, New York, and an addition to the plant was completed in 1966. The plant was devoted to the manufacture of high-precision ball and roller bearings.
In 1964, Marlin Rockwell Corporation
was merged with TRW, Incorporated, and renamed TRW Bearings Division in 1979. With the technological background and facili- ties of the parent company at its disposal, TRW Bearings Division entered a new period of growth. A ball manufacturing plant was acquired in 1964 at Winstead, Connecticut. In 1976, the Division built a new facility at Gainesville, Georgia, to specialize in high- volume bearing production.
In 1986, the Bearing Division was acquired by the SKF Group, which is an international manufacturing and marketing organization composing approximately 200 companies with 85 factories, together operating in more than 130 countries. SKF sales units are backed up by nearly 200 sales offices and over 10,000 distributors and retailers.
