Timken Co's Business Segments

The Company was founded in 1899 by Henry Timken, who received two patents on the design of a tapered roller bearing. Timken later became, and continues to be, the worlds largest manufacturer of tapered roller bearings, leveraging its expertise to develop a full portfolio of industry-leading products and services. Timken built its reputation as a global leader by applying its knowledge of metallurgy, friction management and mechanical power transmission to increase the reliability and efficiency of its customers equipment across a diverse range of industries. Today, the Companys global footprint consists of 73 manufacturing facilities/service centers, 15 technology and engineering centers, and 25 distribution centers and warehouses, supported by a team comprised of more than 14,000 employees. Timken operates in 28 countries around the globe.

Engineered Bearings:
The Timken® bearing portfolio features a broad range of anti-friction bearing products, including tapered, spherical and cylindrical roller bearings; thrust and ball bearings; and housed units. Timken is a leading authority on tapered roller bearings, and leverages its position by applying engineering know-how and technology across its entire bearing portfolio.

A bearing is a mechanical device that reduces friction between moving parts. The purpose of a bearing is to carry a load while allowing a machine shaft to rotate freely. The basic elements of the bearing include two rings, called races; a set of rollers that rotate around the bearing raceway; and a cage to separate and guide the rolling elements. Bearings come in a number of designs, featuring tapered, spherical, cylindrical or ball rolling elements. The various bearing designs accommodate radial and/or thrust loads differently, making certain bearing types better suited for specific applications.

Selection and development of bearings for customer applications and demand for high reliability require sophisticated engineering and analytical techniques. High precision tolerances, proprietary internal geometries and quality materials provide Timken bearings with high load-carrying capacity, excellent friction-reducing qualities and long service lives. The uses for bearings are diverse and can be found in transportation applications that include passenger cars and trucks, heavy trucks, helicopters, airplanes and trains. Ranging in size from precision bearings the size of a pencil eraser to those roughly three meters in diameter, Timken components are also used in a wide variety of industrial applications: paper and steel mills, mining, oil and gas extraction and production, machine tools, gear drives, health and positioning control, wind turbines and food processing.

Tapered Roller Bearings. Timken tapered roller bearings can increase power density and can include customized geometries, engineered surfaces and specialized sealing solutions. The Company’s tapered roller bearing line comes in thousands of combinations in single-, double- and four-row configurations. Tapered roller designs permit ready absorption of both radial and axial load combinations, which makes them particularly well-adapted to reducing friction where shafts, gears or wheels are used.

Spherical and Cylindrical Roller Bearings. Timken also produces spherical and cylindrical roller bearings that are used in large gear drives, rolling mills and other industrial and infrastructure development applications. These products are sold worldwide to original equipment manufacturers ("OEMs") and industrial distributors serving major end-market sectors, including construction and mining, natural resources, defense, pulp and paper production, rolling mills and general industrial goods.

Ball Bearings. Timken radial, angular and precision ball bearings are used by customers in a variety of market sectors, including aerospace, agriculture, construction, health, machine tool and general industries. Radial ball bearings are designed to tolerate relatively high-speed operation under a range of load conditions. These bearing types consist of an inner and outer ring with a cage containing a complement of precision balls. Angular contact ball bearings are designed for a combination of radial and axial loading. Precision ball bearings are manufactured to tight tolerances and come in miniature and instrument, thin section and ball screw support designs.

Housed Units. Timken markets among the broadest range of bearing housed units in the industry. These products deliver durable, heavy-duty components designed to protect spherical, tapered and ball bearings in debris-filled, contaminated or high-moisture environments. Common housed unit applications include material handling and processing equipment.

Mechanical Power Transmission:
Belts. Timken makes and markets a full line of Carlisle® belts used in industrial, commercial and consumer applications. The portfolio features more than 20,000 parts designed for demanding applications, which are sold to original equipment and aftermarket customers. Carlisle® belts are engineered for maximum performance and durability, with products available in wrap molded, raw edge, v-ribbed and synchronous belt designs. Common applications include agriculture, construction, industrial machinery, outdoor power equipment and powersports.

Chain. Timken manufactures precision Drives® roller chain, pintle chain, agricultural conveyor chain, engineering class chain and oil field roller chain. These highly engineered products are used in a wide range of mobile and industrial machinery applications, including agriculture, oil and gas, aggregate and mining, primary metals, forest products and other heavy industries. These products are also utilized in the food and beverage and packaged goods sectors, which often require high-end, specialty products, including stainless-steel and corrosion-resistant roller chain.

Couplings. The Company offers a full range of industrial couplings within its mechanical power transmission products portfolio. The Lovejoy brand is widely known for its flexible coupling design and as the creator of the jaw-style coupling. Lovejoy® couplings are available in curved jaw, jaw in-shear, s-flex, gear-torsional and disc style configurations. These components are used in a wide range of industries such as steel, pulp and paper, power generation, food processing, mining and construction.

Lubrication Systems. The Company offers 27 formulations of grease, leveraging its knowledge of tribology and anti-friction bearings to enable smooth equipment operation. Interlube® automated lubrication delivery systems dispense precise amounts of Timken grease, saving users from having to manually apply lubrication. These multifaceted delivery systems are used by the commercial vehicle, construction, mining, and heavy and general industries.

Aerospace Products. The Companys portfolio of parts, systems and services for the aerospace market sector includes products used in helicopters and fixed-wing aircraft for the military and commercial aviation industries. Timken designs, manufactures and tests a wide variety of power transmission and drive train components, including bearings, transmissions, turbine engine components, gears and rotor-head assemblies and housings. In addition to original equipment, Timken provides aftermarket component repair for bearings and compressor cases. Timken inspects and reconditions main engine, gearbox and APU bearings on a wide range of platforms, such as engines, transmissions and gearboxes.

Industrial Gearboxes. The Company’s Philadelphia Gear® line of low- and high-speed gear drive designs are used in large-scale industrial applications. These gear drive configurations are custom-made to meet user specifications, offering a wide-array of size, footprint and gear arrangements. Low-speed drives are commonly used in crushing and pulverizing equipment, cooling towers, conveyors and pumps. High-speed drives are typically used by power generation, oil and gas, marine and pipeline industries.

Other Products. The Company also offers a full line of seals, augers and other mechanical power transmission components. Timken industrial sealing solutions come in a variety of types and material options that are used in manufacturing, food processing, mining, power generation, chemical processing, primary metals, pulp and paper, and oil and gas industry applications. The Company also designs and manufactures Drives helicoid and sectional augers for agricultural applications, like conveying, digging and combines.

Services:
Power Systems. Timken services components in the industrial customers drive train, including switch gears, electric motors and generators, gearboxes, bearings, couplings and central panels.
