AIA:Bearings Keep Engines Rolling
Approximately 40 years ago, Timken Co. (Canton, OH) designed bearings for Rolls- Royce Corp.'s original Model 250 aircraft engine. Over the years, Timken Aerospace, a subsidiary of The Timken Co., has supplied 27 bearing part numbers for the engines. Rolls-Royce wants that trend to continue. So now whenever Rolls-Royce needs new bearings, it looks no further than Timken. Timken Co. is the sole provider of bearings for the Model 250 engines, and the new agreement will add 11 additional bearing part numbers.
The compact, 420- to 715-shaft horsepower engines are used in half the world's light single- and twin-engine helicopters. More than 28,500 engines have been delivered, and more than 15,000 are currently in service in helicopters and general aviation around the world. The engine has 4,500 customers, including more than 135 military and paramilitary operators in 90 countries.
Production is approximately 250 engines per year. However, production could easily be increased to more than 30,000 engines.
