Propeller Shaft FAQ

What materials are used for marine propeller shafts?

We manufacture marine propeller shafts from stainless steel (316, 304), Aqualoy 22, alloy steel, and other corrosion-resistant materials. Material selection depends on vessel size, operating environment, and saltwater exposure. All materials are selected for maximum corrosion resistance and durability in marine conditions.

Can you produce custom length propeller shafts?

Yes, we manufacture custom propeller shafts up to 236″ in length. Our engineering team works from your vessel specifications to produce shafts with exact dimensions, taper specifications, and coupling configurations. We support both new builds and replacement shaft requirements.

What is your propeller shaft straightness tolerance?

Our precision manufacturing achieves straightness tolerances up to .0002″ for propeller shafts. This exceptional accuracy ensures smooth rotation, minimizes vibration, and maximizes bearing life. Every shaft undergoes comprehensive straightness inspection and dynamic balancing.

Do you provide surface treatments for corrosion protection?

Yes, we offer various surface treatments including electropolishing, passivation, and protective coatings specifically designed for marine environments. These treatments enhance corrosion resistance, reduce marine growth adhesion, and extend service life in saltwater applications.

What quality testing do you perform on propeller shafts?

Every propeller shaft undergoes comprehensive testing including dimensional verification, straightness measurement, runout testing, dynamic balancing, ultrasonic testing for internal defects, and material certification. We provide detailed inspection reports with all deliveries.

Can you manufacture intermediate shafts and stern tubes?

Yes, we manufacture complete propeller shaft systems including intermediate shafts, stern tube assemblies, and coupling components. Our comprehensive manufacturing capabilities allow us to provide complete propulsion shaft solutions for marine vessels of all sizes.
