Step-by-step explanation:
The historical perspective
of MRC
MRC is the outgrowth of three of America’s
oldest bearing companies—Standard Roller
Bearing Company, Gurney Ball Bearing Company, and Strom Bearing Company.
The Standard Roller Bearing Company
was formed when a Philadelphia industrialist,
S. S. Eveland, merged the Ball Bearing Company of Boston with seven other major ball
bearing and ball-making equipment manufacturers. The company used the SRB Diamond trademark. SRB made many contributions 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 incorporated 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 mounting and maintenance.”
Prior to World War I, Albert F. Rockwell,
one of two brothers who founded New Departure Company, formed the RockwellDrake Corporation to manufacture ball bearings in Plainville, Connecticut. During the war,
Rockwell combined Rockwell-Drake Corporation with several other corporations including
the Standard Roller Bearing Company of
Philadelphia.
After World War I, some of the manufacturing units were liquidated and the company
was reorganized as Standard Steel and
Bearing, Inc., Division of Marlin Rockwell
Corporation. In 1923, the bearing manufacturing plants were consolidated at Plainville,
Connecticut. The following year, Gurney Ball
Bearing Company merged with Marlin Rockwell 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 Rockwell 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 facilities 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 highvolume 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
