🚤 Submarine & Naval Propulsion Components

Large-diameter thin-wall cylindrical bushings/bearings with precision bore tolerance, keyway slots, threaded mounting holes

Design Principles

Material: Grade 5 (Ti-6Al-4V) for propellers, shafts, and structural components. Grade 5 ELI for deep-sea pressure vessels requiring maximum fracture toughness. Grade 7 (Pd alloy) for hot chemical injection lin

Form: Bar/forging stock for shafts and structural components. Investment casting for impeller blades. Ring forgings for flanges. All marine fasteners must be hot-headed + thread rolled with vacuum annealing

Engineering Trends

  • ▸ Process: CNC turning & boring of ID/OD
  • ▸ Process: Keyway broaching
  • ▸ Process: Precision honing of bearing surface
