Ship engine parts include components like pistons, crankshafts, and cylinders that convert fuel into mechanical energy. Engine parts such as valves, camshafts, and fuel injectors ensure efficient combustion and power generation. These parts work together to propel the ship and maintain optimal performance.

Viscosity: Lubricating oils: ISO VG 68–150, hydraulic fluids: ISO VG 32–46

Buoyancy: Not applicable for most engine parts (non-floating components)

Material: Cast iron, forged steel, aluminum alloys, bronze, stainless steel

Heat Treatment: Quenching, tempering, case hardening (HRC 45–60)

Surface Finish: Ra 0.8–3.2 μm for bearings, Ra 1.6–6.3 μm for gears

Tolerance: ±0.005mm–±0.05mm depending on part precision
