150–450mm Marine Roller Fairlead with Verified SWL & Safety Factor for Ship Mooring
Product Overview
This marine roller fairlead is designed as a load-bearing guiding device for mooring systems.
Unlike conventional fairleads, this unit is engineered with verified Safe Working Load (SWL) and safety factor, ensuring reliable performance under real mooring forces.
High-quality cast steel rollers, precision machining, and optimized lubrication system ensure smooth rotation and reduced rope wear.
Suitable for both steel wire rope and synthetic ropes in demanding marine environments.

Selection Guide
Step 1 – Select Roller Diameter → Based on rope size
Step 2 – Confirm Rope Type → Steel wire or synthetic rope
Step 3 – Confirm SWL → Must exceed maximum mooring load
Step 4 – Check Safety Factor → Higher for dynamic conditions
Step 5 – Select Roller Quantity → Based on lead angle
Step 6 – Confirm Lubrication → For long-term reliability
Structure
Cast steel rollers | Steel base | Shaft | Copper bush | Lubrication channels
Custom Attributes
Inquiry Guide
Provide rope diameter, SWL requirement, rope type, roller number, and certification requirement.
How It Works
The rope passes over rotating rollers which reduce friction and distribute load. SWL ensures safe operation under defined loads.
Applications
Ship mooring system | Rope guiding under load | Steel wire rope handling
Certifications & Advantages
Certification: CCS, NK, BV, ABS, DNV, LR, KR, IRS, RS, RINA, CRS; verified SWL, reduced rope wear, smooth rotation, high structural reliability.
