Dimensional Reference (ISO 4566 Conformity)
- A = 1000 mm – Shaft length
- D = 25 mm – Shaft diameter
- F = 8 mm – Key width
- I = 3 mm – Key depth
- O = M16 × 1.5 – Thread size
- Y = 25 mm – Start of taper
- Z = 55 mm – Taper length
Advantages
- Manufactured from duplex stainless steel 1.4462 for maximum longevity
- Exceptional strength and hardness provide stable bearing performance
- Integrated zinc anode ensures continuous galvanic protection
- ISO 4566-compliant taper and keyway guarantee propeller compatibility
