AISI 316 Stainless Steel Split Propeller Shaft Rope Cutter Ø25–50 mm
AISI 316 Stainless Steel Split Propeller Shaft Rope Cutters are designed for marine propulsion installations where nylon ropes, stainless steel cables or fishing nets may become entangled around the propeller shaft. The circular cutter features a toothed cutting edge and a two-piece construction that allows installation and removal without removing the propeller.
Manufactured from AISI 316 stainless steel, the range includes six configurations suitable for propeller shaft diameters from 25 to 50 mm.
Two-Piece Split Construction
The rope cutter consists of two separate sections that form a circular cutting assembly around the propeller shaft.
This split design allows the cutter to be installed or removed without taking off the propeller, making it convenient for maintenance and replacement.
AISI 316 Stainless Steel Construction
Each cutter is manufactured from AISI 316 stainless steel, providing corrosion-resistant construction for marine applications.
Toothed Circular Cutting Edge
The cutter features teeth around its outer circumference, designed to cut ropes, cables and netting that may become entangled around the propeller shaft.
Rope, Cable and Net Cutting
The cutter is specified for:
- Nylon ropes.
- Stainless steel cables with diameters from 4 to 6 mm.
- Fishing nets and netting materials.
Installation Without Propeller Removal
The two-piece construction allows the cutter to be fitted around the shaft without dismantling the propeller. This makes installation, inspection and replacement more convenient.
Available Shaft Diameters
Six versions are available for the following propeller shaft diameters:
- Ø25 mm
- Ø30 mm
- Ø35 mm
- Ø40 mm
- Ø45 mm
- Ø50 mm
External Diameter and Thickness
The external diameter varies according to the selected shaft size:
- 25 and 30 mm shafts: 80 mm external diameter.
- 35 and 40 mm shafts: 100 mm external diameter.
- 45 and 50 mm shafts: 120 mm external diameter.
All six configurations have a thickness of 22 mm.
