Crank and balance shaft

The crankshaft is one of the most important parts of the engine. Crankshaft support bearings take all the pressure generated by the engine power stroke.

The main technical demands for the crankshaft bearings in two and three wheelers applications are:

  • Crankshaft accurate guidance resulting from limited radial and axial clearance value.
  • Heat transfer resistance from engine combustion chambers
  • Protection to support engine oil solid and chemical contaminants
  • Long service life in terms of rolling contact fatigue resistance
  • Structural fatigue resistance (outer ring) due to housing deformation

SKF has developed and supplies a wide range of crank and camshaft bearing designs for two and three wheelers engine applications.
