Engineering Services

Gear Design for parallel axis, planetary, bevel, face gears, worm and crossed axis helical; existing designs to new concept, metal or plastic.

Failure analysis preformed for gearing, shafts and bearings.

Optimization of existing gear drives: Noise reduction, increased efficiency, size reduction.

Complete transmission design including all gearing, shafts and bearings.

Industries served include automotive, aerospace, wind power, agriculture, construction, appliance, power tool, nuclear energy, medical devices, oil exploration, printing, textile and more.

Our engineers feature about 90 years of experience in the field of gearbox design. Here is a listing of some projects accomplished successfully by them. The listing is split in the work handled mainly in the USA, and the part which was done primarily in Europe. However, whenever necessary our engineers join forces over the Atlantic ocean, to provide maximum benefit to the client.
