Osculati Stainless Steel Split Propeller Shaft Rope Cutter with Clamp System Ø25–50 mm

Osculati Stainless Steel Split Propeller Shaft Rope Cutter with Clamp System Ø25–50 mm

Osculati Stainless Steel Split Propeller Shaft Rope Cutters are designed for marine propulsion shaft installations. Featuring a toothed circular cutting edge and a split clamp construction, these cutters can be installed around the propeller shaft without disassembling the propeller.

The Osculati 52.961 series includes eight configurations for shaft diameters from 25 to 50 mm, with external cutter diameters from 80 to 120 mm. All versions have a thickness of 22 mm.

Split Clamp Construction

The cutter features a split circular body with a clamp fastening system. This construction allows the cutter to be fitted around the propeller shaft without removing the propeller.

The clamp arrangement simplifies installation during maintenance and servicing of the marine shaft assembly.

Stainless Steel Construction

The cutters are manufactured from stainless steel and feature a toothed outer cutting edge.

Toothed Circular Cutting Design

The circular cutter incorporates a series of teeth around its external circumference for cutting lines that may become entangled around the propeller shaft.

Metric and Imperial Shaft Diameters

The range includes versions for metric propeller shafts and two imperial shaft sizes:

• 25 mm
• 30 mm
• 31.75 mm (1 1/4")
• 35 mm
• 40 mm
• 44.5 mm (1 3/4")
• 45 mm
• 50 mm

Cutter Dimensions

The manufacturer's technical drawing identifies the following measurements:

• Ø A – Shaft Diameter: Internal mounting diameter corresponding to the propeller shaft.
• Ø B – External Diameter: Overall outside diameter of the cutter.
• Thickness: Axial thickness of the cutter assembly.

Available Models and Dimensions

The following table lists all eight configurations according to the Osculati technical catalogue. Dimensions are expressed in millimetres unless otherwise indicated.

External Diameter by Shaft Size

The cutter's external diameter depends on the selected shaft diameter:
