Marine Roller Fairlead

Marine Roller Fairlead

Marine Roller Fairlead is a critical equipment used in ships and marine engineering to guide and protect mooring ropes,chains, ensuring smooth movement under stress and reducing wear and friction. Fairlead rollers are usually fixed on a bracket with two or more rollers, and are mostly made of high-strength steel.
Maintenance and upkeep tips: Regular inspections; Lubricate roller bearings; Remove salt and dirt.

We can also provide customized chain stoppers according to your drawings.

Structural Design

Roller Assembly: Composed of horizontal/vertical rollers (diameter range: 100mm - 450mm) mounted on a sturdy frame.

Base Structure: Conical or flat base with dimensions varying by model (e.g., for 150mm roller, base size is 240mm in diameter, 195mm in height).

Material Specifications

Cast Iron (HT): HT200, tensile strength ≥200MPa, suitable for general marine environments.

Cast Steel (ZG): ZG230-450, tensile strength 450-580MPa, preferred for high-load applications.

Surface Treatment: Zinc plating or bitumen paint for corrosion resistance.
