Crank Pins

• Our crank pins, for built crankshafts, are produced on turning machines. The outside edge chamfers of the crank pins are manufactured using special vibrating grinding machines. The advantages of vibrating grinding of the edge curvature are:
  • The pressing is perfectly aligned due to the precise chamfer of the circumference.
  • A shallow outside form angle is important in producing higher transferable engine torque of the built crankshaft.
• We finish the crank pins in our own heat treatment and grinding department.
• If required the crank pins can be coated in order to increase the transmitted torque. (up to 100 %).
• We produce only according to customers blueprints.
