20–76mm 360° Swivel Head Fairlead | Rotating Casting Steel Fairlead for Ship Mooring & Towing
Product Overview
360-degree swivel head fairlead is designed for guiding and redirecting mooring and towing ropes with flexible orientation.
The swivel head allows rotation to accommodate changing rope lead angles, reducing friction and improving rope alignment.
It is widely used on tugboats, offshore platforms, engineering vessels and mooring systems requiring dynamic rope direction control.

Selection Guide
Step 1 – Select rope diameter → Based on wire size
Step 2 – Confirm load requirement → Based on breaking strength
Breaking strength represents the structural capacity of the fairlead and should be properly matched with the rope’s breaking load for safe selection.
Step 3 – Confirm rotation requirement → Swivel angle needed
Step 4 – Confirm installation location → Deck or structure
Step 5 – Confirm certification requirement

Why Swivel Head Design?
Allows rope to follow changing direction → Reduces side load
Improves rope alignment → Prevents twisting and uneven tension
Reduces friction → Extends rope service life
Swivel mechanism is designed to reduce side load on the sheave and prevent uneven wear of the rope.
Custom Attributes
360° swivel capability → Flexible rope direction
Heavy-duty structure → Suitable for towing loads
Smooth sheave surface → Protects rope
High-strength materials → Long service life
Stable base mounting → Secure installation
Inquiry Guide
Please provide rope diameter, load requirement, swivel angle, installation condition and certification requirement.
How It Works
The rope passes over the sheave while the swivel head rotates to align with the rope direction, reducing side forces and ensuring smooth operation.
Applications
Tugboats | Offshore platforms | Mooring systems | Towing operations
