Crankshaft bearing cap

Crankshaft bearing cap

Crankshaft bearings caps (also known as main bearing caps) are subject to heavy loads and need to be extremely crack-resistant. Choosing powder metallurgy (PM) over an alternative manufacturing process provides excellent near net-shape geometry and fatigue resistance and eliminates preassembly machining steps. PM bearing caps usually require only one line-boring step during installation, which translates into a substantial cost saving.

Höganäs machining enhancers further reduce production cost by providing excellent machinability of line-boring after pre-assembly, which reduces tool wear.



Benefits of Höganäs’ solution for PM bearing caps:

  • Near net-shape manufacturing
  • Excellent fatigue properties
  • Lightweight design
  • Improved machining
