Marine Engine Crankshafts & Camshafts

At Sourcing Marine, we specialize in the “backbone” of the marine diesel engine: Crankshafts and Camshafts. As the most critical rotating components, these shafts must manage immense torsional loads and provide perfect timing for fuel injection and valve operation.

  • OEM-Grade Precision: Machined to exact tolerances to ensure perfect oil film thickness and hydrodynamic lubrication at the bearings.
  • Surface Integrity: Induction-hardened journals and lobes for superior wear resistance and extended service life.
  • Certified Quality: All shafts are available with material and class certifications, providing the trust and reliability your vessel requires.

Product Description

We maintain a deep inventory of both crankshafts and camshafts for the world’s leading 4-stroke auxiliary and medium-speed engines. Every shaft in our inventory is manufactured to OEM standards, featuring precision-ground journals, induction-hardened surfaces, and strict balancing to ensure long-term mechanical reliability and vibration-free operation.
