A Company Profile

Allen Gears is a company within the Industrial Businesses Sector of Rolls-Royce. We design and manufacture high quality precision epicyclic, parallel shaft or combination gearing to worldwide industrial and marine markets.

Company History

In 1948 Allen Gears commenced the development of an Epicyclic Gear having special design features patented by the late Dr. Stoeckicht. Following two years of work, practical designs for a range of industrial epicyclic gears were produced and Allen Gears entered into a licence agreement for their manufacture.

In order to realise the full potential of the Allen-Stoeckicht Epicyclic gears it was decided to set up Allen Gears at Pershore in 1956. Over 5,000 gears of this epicyclic type, totalling some 30 million horsepower, have been designed and manufactured at Pershore.
