Precision Cylindrical and Ball Bearings.  Timken’s aerospace facilities produce high-performance ball and cylindrical bearings for ultra high-speed and/or high-accuracy applications in the aerospace, medical and dental, computer and other industries. These bearings utilize ball and straight rolling elements and are in the super precision end of the general ball and straight roller bearing product range in the bearing industry. A majority of these bearings products are custom-designed bearings and spindle assemblies. They often involve specialized materials and coatings for use in applications that subject the bearings to extreme operating conditions of speed and temperature. 

Spherical and Cylindrical Roller Bearings.  Timken produces spherical and cylindrical roller bearings for large gear drives, rolling mills and other industrial and infrastructure development applications. These products are sold worldwide to original equipment manufacturers and industrial distributors serving major end-markets, including construction and mining, natural resources, defense, pulp and paper production, rolling mills and general industrial goods. The same rigorous analysis and development apply to these products as well. 

Chains and Augers.  Through the acquisition of Drives LLC in 2011, Timken now manufactures American National Standards Institute (ANSI) precision roller chain, pintle chain, agricultural conveyor chain, engineering class chain, oil field roller chain and auger products. These highly engineered products are vital to 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, including food and beverage and packaged goods sectors, which often require high-end, specialty products such as stainless-steel and corrosion-resistant roller chains. 

Gear-Drive Systems.  Through the acquisition of Philadelphia Gear Corp. in 2011, Timken now provides aftermarket gear box repair services and gear-drive systems for the industrial, energy and military marine sectors, including refining and pipeline systems, mining, cement, pulp and paper making and water management systems. 

Services.  Timken also provides bearing reconditioning and repair; condition monitoring and reliability services to maximize performance, durability and maintenance intervals for industrial and railroad customers, both domestically and internationally. Other services include maintenance and rework services for large industrial equipment used in metal mills and energy sectors. The total services accounted for less than 5% of the Company’s net sales for the year ended December 31, 2011. 

Aerospace Products and Services.  Timken’s portfolio of parts, systems and services for the aerospace market has grown to include products used in helicopters and fixed-wing aircraft for the military and commercial aviation industries. Timken provides design, manufacturing and testing for a wide variety of power transmission and drive train components including bearings, transmissions, turbine engine components, gears and rotor-head assemblies and housings. Other parts include airfoils (such as blades, vanes, rotors and diffusers), nozzles and other precision flight-critical components. 

In addition to original equipment, Timken provides a wide range of aftermarket products and services for global customers, including complete engine overhaul, bearing repair, component reconditioning and replacement parts for gas turbine engines, transmissions and fuel controls, gearboxes and accessory systems in helicopters and fixed-wing aircraft. Our precision bearings also have applications in spacecraft and robotic vehicles, like Curiosity, the newest Mars Rover. Customers for these precision bearings also include manufacturers of medical and health equipment, machine tools, industrial motion control systems and precision robotics. 

Steel.  Timken produces more than 450 grades of carbon, micro-alloy and alloy steel, which are sold as ingots, bars and tubes in a variety of chemistries, lengths and finishes. Our metallurgical expertise and operational capabilities enable us to provide customized solutions for the automotive, industrial and energy sectors. Timken ®  specialty steels are used in a wide variety of end products including oil country drill pipe, bits and collars, gears, hubs, axles, crankshafts and connecting rods, bearing races and rolling elements, bushings, fuel injectors, wind energy shafts and other demanding applications, where mechanical power transmission is critical to the end customer. 

Precision Steel Components.  Timken also produces custom-made steel products, including steel components for automotive and industrial customers. Steel components have provided the Company with the opportunity to further expand its market for tubing and capture higher value-added steel sales by streamlining customer supply chains. It also enables Timken’s traditional tubing customers in the automotive and bearing industries to take advantage of ready-to-finish components that cost less than other alternatives. Customization of products is an important component of the Company’s steel business where mechanical power transmission is critical to the end customer.
