Timken recently expanded its aerospace aftermarket facility in Mesa, Ariz., with offerings aimed primarily at the turbine-powered civil and military rotorcraft markets. Many overhaul facilities turn to Timken for its repertoire of FAA parts manufacturing approved (PMA) items–more than 1,600 in all–as well as component overhaul and repair, bearing repair and parts replacement services. Timken Aerospace offers full overhaul for the PT6A, PT6T TwinPac and T53 engines. Its aftermarket facility is an end-to-end operation, from technology development and engineering, through machining, parts manufacturing, quality assurance and repair to fleet support. It includes a multi-purpose foundry that provides a variety of castings for Timken-manufactured, OEM-approved parts ranging from gas-turbine engine nozzles, vane segments and turbine blades to engine and airframe structural parts. Timken aftermarket support capabilities have expanded through acquisition of eight firms over the past six-and-a-half years. The most recent, ExTex and its PMAs for the Rolls-Royce 250, Pratt & Whitney Canada PT6 and APUs along with PT6A overhaul capabilities, has been relocated from Tucson to the Mesa operation.
