Propeller Shaft Alignment Gauges are precision tools used in marine propulsion to ensure accurate alignment of the propeller shaft with the engine and stern tube. These gauges help measure and correct misalignments, preventing excessive wear and vibration. Proper alignment enhances efficiency, reduces fuel consumption, and prolongs the lifespan of marine propulsion systems.

Size: Typically ranges from 300 mm to 1500 mm in length, depending on vessel size.

Grade: High-precision, marine-grade components for accurate alignment.

Viscosity: Not applicable (mechanical tool, no fluid properties).

Buoyancy: Neutral or negligible (designed for dry or submerged use in alignment checks).

Material: Stainless steel (AISI 316 or equivalent) for corrosion resistance.

Accuracy: ±0.02 mm/m for shaft alignment precision.

Operating Temperature: -20°C to +60°C (marine environment range).

Load Capacity: Varies by model, typically up to 50 kN for heavy-duty applications.

Finish: Polished or coated for durability in saltwater conditions.

Compatibility: Suitable for propeller shafts of 50 mm to 500 mm diameter.

Propeller Shaft Alignment Gauges for Marine Propulsion typically comply with maritime standards such as ISO 484, ISO 862, and ABS, DNV, or Lloyd's Register guidelines, depending on the manufacturer and specific product specifications.
