Timken Aerospace Aftermarket Solutions’ $400 million in annual revenues represents a relatively small portion of parent Timken Company’s $4 billion total, but the Mesa, Ariz.-based aftermarket specialist is aiming higher as it moves into the new decade.

“From engineering and manufacturing to repair and fleet support, Timken is one of the few aerospace aftermarket service providers to offer a fully comprehensive MRO program,” said Larry Shiembob, general manager for maintenance repair and overhaul for Timken Aerospace.

Among the more recent moves by the group is an expansion of its engine overhaul business, which now includes Rolls-Royce 250, Honeywell T53 and Pratt & Whitney Canada PT6T Twin-Pac and PT6A turboshaft PMA (parts manufacturer approval) parts manufacturing, repair and overhaul. In recent months, the group also opened a new engine facility in Mesa that combined the assets of its Tucson works and a smaller repair shop already established in Mesa. The new shop is dedicated to engine and drive train overhaul.

“We do it all here in Mesa,” said Shiembob, referring to the 85,000-sq-ft center next to Falcon Field airport. “This is our aftermarket center for parts production and engine overhaul.” He noted that the group now has some 2,000 different FAA-approved PMA replacement parts, from turbine blades to compressors. The group also supplies most of the parts that drive overhaul costs, including wheels, combustion liners, nozzles, bearings and gears. It also offers in-house casting, vacuum molding and machining capabilities.

As part of the Timken Aerospace aftermarket mission, said Shiembob, “We’re taking the technology developed over more than 110 years by our parent company and applying it to aerospace, and we are developing our own new technology for the aftermarket business.”

At its Heli-Expo 2011 exhibit (Booth No. 1306), Timken will be featuring newly developed helicopter parts with a primary focus on transmission and rotor head parts.

A major part of the aftermarket group’s long-term strategy is expansion by acquisition. Since 2005, it has snapped up a half-dozen companies with a considerable collective experience in aftermarket products. Among them are: CAM, a helicopter drive-train specialist; Bii, bearing repairs; Sermatech International, turbine compressor specialist; and Purdy, with expertise in gears, gearboxes and transmission capabilities.

In 2008, Timken acquired Extex of Gilbert, Ariz., which brought under the Timken umbrella a number of Rolls-Royce 250 and P&WC PT6T PMAs, along with foundry and component machining experience.

Most recently the group has added the assets of Alcor Engine, also of Gilbert, Ariz. With more than 20 trained aviation technicians, Alcor produces direct replacement parts for aviation gas turbine engines and components. As a newly formed subsidiary, Alcor has been rebranded Timken Alcor Aerospace Technologies.

The result of all this, said Shiembob, “is an end-to-end, turnkey solution for helicopter operators, a demonstration of our commitment to aftermarket support.”

Also at its Heli-Expo exhibit, Timken Aerospace Aftermarket will be showing a number of products for which it recently received PMAs: including a retention strap fitting, collective sleeve, swashplate ring assembly, pillow block bolt, swashplate support assembly and main rotor blade bolt. In 2010, the group received PMA approvals for 28 different parts.

The Timken Company was founded in 1899 by Louis Timken and its headquarters are in Canton, Ohio. Its patented, tapered roller bearing formed the basis of an extensive line of friction management and power transmission products, and since 1917, specialty alloy steel production.
