Engine components

Crankshafts are used in nearly every type of combustion engine. These components are critical to successful, trouble-free motor function – and not only now, but over many years.

Today millions of crankshafts leave our plants every year, either as blanks or finished parts, on their way to locations all over the world. That makes us the global market leader in this area.

Forged crankshafts

The range of forged crankshafts available from thyssenkrupp includes blanks for both diesel and gasoline engines in every common version, such as in-line or boxer, and for V and W engines, no matter if they will be used in motorcycles, passenger cars or utility vehicles or in machines, ships or generators. Such blanks can weigh up to 250 kg with a maximum length of 1.5 meters.

Characteristics/Development services:

  • Microalloyed, alloyed and unalloyed steels
  • Blank development
  • (New) design and calculation of safety factors
  • Design optimization
  • Production of prototypes
  • Design and manufacturing of forging tools
  • Forming simulation and forging process optimization

Finished crankshafts

For utility vehicles, we supply completely assembled, ready-to-install crankshafts with various surface treatments, such as inductive hardening, rolled radii or nitriding.

Our finished crankshafts weigh up to 200 kg, are up to 1.5 m long and are used in utility vehicles and machines as well as in industrial and ship motors. We also offer blank finishing for passenger car applications.

Additionally, our service includes crankshaft repair.

Characteristics/Development services:

  • Microalloyed, alloyed and unalloyed steels

  • Cast iron (utility vehicle crankshafts)

  • Design optimization

  • Production of prototypes

  • Non-destructive testing: US and Magnaflux

  • Simultaneous engineering with our customers

Conrods

thyssenkrupp produces both offset and straight conrods weighing up to 20 kg with the application of conventional splitting or the “fracture split method”. The conrods are used in both gasoline and diesel passenger car motors as well as in diesel motors for utility vehicles, generators and ships. Our partners have a choice here between forged blanks and finished, ready-to-install conrods. Moreover, we offer our customers development services from raw part design and calculation to finished part design and process optimization.

  • Microalloyed, alloyed and unalloyed steels
  • Design
  • Simultaneous engineering with our customers

Pistons

The production of pistons rounds out the product range in the area of motor components. We develop and produce various versions of forged or partially finished piston crowns for medium-weight and heavy diesel motors.

Characteristics:

  • Microalloyed, alloyed and unalloyed steels
  • With joint
  • Upper and lower part
  • Integrated (upper and lower part, shaft)
  • Multi-axial design
