Rail

Hofmann Engineering has provided engineered rail solutions for over 40 years and is a single source provider for all types of machined components. Hofmann Engineering has extensive experience in precision machining and offer efficient production services backed by ISO 9001:2000 and AS9100 compliant quality management systems. Bull gears and pinions are manufactured for most makes of locomotive (GE, Alco etc).

BULL GEARS

  • Case carburised & shot peened and ground and / or skived.
  • Tooth by tooth full contour induction hardened and ground.
  • Profile regrinding of old worn bull gears.

PINIONS

Case carburised and accurately ground including taper crowning. A shot peened full root radius on our pinions provides a substantial strength increase.

SPIRAL BEVEL GEARS

  • Case carburised to 58 � 62 HRc and precision hard cut to DIN Class 3.
  • Capacity to manufacture spiral bevel gearing up to �2m.
