Counterweighting methods

Monday, October 12, 2009
Comments (1)

In the design of crankshafts we have to incorporate counterweighting for various reasons, either for reduction of bearing loads, or to reduce or eliminate primary couples. Often this is achieved through careful design of the crankshaft and the count... read more

Crankshaft Steels

Sunday, June 14, 2009
Comments (1)

As was mentioned in the previous RET Monitor article on crankshafts, it is our belief that nitriding steels are the most commonly, if not exclusively used materials. This month we take a closer look at nitriding steels for crankshaft manufacture, exp... read more
