JIS F 2014 Casting Open Type 2 Rollers Shipside Fairlead Rollers Ship Mooring Equipment

Open Type Two-Roller Shipside Fairlead | JIS F 2014 AF Cast Roller Mooring Equipment

Product Overview

The JIS F 2014 AF open type two-roller shipside fairlead is a ship mooring rope guide used at the vessel side, bulwark, or deck-edge mooring area. Its open arrangement allows the mooring line to enter the fairlead from the top side and pass over two rotating rollers, helping guide the rope path and reduce direct rubbing against the ship structure.

This page is written for the casting roller version of the open type two-roller fairlead. In JIS F 2014, AF refers to the open type fairlead with two cast rollers, while AS refers to the open type fairlead with two steel plate fabricated rollers. For quotation and production, the final roller material, shaft material, surface treatment, installation drawing, and certificate scope should be confirmed according to the vessel specification.

Quick Specifications

• Product type: Open type two-roller shipside fairlead → suitable for shipside mooring rope guidance where an open rope-entry arrangement is required.

• Standard and type: JIS F 2014-1987 AF → open type fairlead with two cast rollers according to the standard type classification.

• Nominal size range: 150 to 400 for AF type → selected by vessel drawing, rope arrangement, and installation space.

• Roller arrangement: 2 rollers → provides a simple rope lead path for standard shipside mooring stations.

• Main dimensions: D, L, l, and l1 → key values for webpage drawing, shipyard layout checking, and inquiry confirmation.

• Reference rope data: wire rope and fibre rope values are provided by the standard table → these references should not be written as product SWL or breaking load.

• Installation position: shipside / bulwark / deck-edge mooring area → surrounding ship structure and reinforcement should be checked by the shipyard or design office.

• Manufacturing focus: cast roller surface, smooth rope-contact radius, free roller rotation, shaft / bush fit, corrosion protection, and maintainable assembly.

Main Technical Parameters

Main webpage dimensions for JIS F 2014 AF open type two-roller shipside fairlead. Dimensions are in mm unless otherwise stated. Reference rope data is for initial selection only and should be checked against the vessel mooring arrangement.

Reference wire rope values in the main table are arranged according to the standard wire rope columns. The exact rope construction and rope diameter should be confirmed by the vessel mooring design or project specification.

Selection & Inquiry Guide

• Step 1: Confirm JIS F 2014 AF open type two-roller shipside fairlead and nominal size 150 / 200 / 250 / 300 / 350 / 400 according to the vessel drawing.

• Step 2: Confirm whether the project requires AF cast roller type instead of AS steel plate fabricated roller type.

• Step 3: Confirm rope type, rope diameter, mooring line direction, shipside installation position, and available installation space.

• Step 4: Confirm material requirement for roller, frame, shaft, bush, fasteners, and stopper parts before production.

• Step 5: Confirm surface treatment: blasting and shop primer, final coating, galvanized finish, polished stainless steel surface, or other specified treatment.

• Step 6: Confirm certificate scope before quotation: maker certificate, material certificate, class certificate, witness inspection, or project-specific approval.

• Step 7: Provide quantity, delivery destination, required delivery time, installation drawing, and reference photos if available.

Structure

Open fairlead frame | Two cast rollers | Roller shaft / pin | Bush or bearing contact area | Stopper and nut arrangement | Shipside mounting interface | Smooth rope-contact surface | Painted or specified surface treatment

Casting, Rotation & Engineering Advantages

• The open type arrangement allows direct rope entry from the upper side, which is useful at shipside mooring stations where the mooring line lead angle changes during berthing or shifting.

• Two rollers guide the mooring line and help reduce direct rope contact with the bulwark, shell edge, or deck structure.

• Cast rollers should be dressed and smoothed at the rope-contact surface to reduce sharp local contact and support rope protection.

• Roller rotation should be checked after assembly so that the rope can pass with reduced friction during mooring operation.

• Shaft, bush, stopper, nut, and grease-related parts should be arranged for inspection and maintenance according to the supplied drawing and project requirement.

• The shipside mounting structure should be checked together with local reinforcement, rope lead angle, and shipyard installation details.

• The page treats reference rope data as a selection reference, not as SWL, MBL, breaking load, or test load.

Custom Attributes

• Standard: JIS F 2014-1987 → use when the shipyard or owner specification requires JIS shipside fairlead dimensions.

• Type: AF open type two-roller fairlead → cast roller version for open shipside mooring rope guidance.

• Nominal Size: 150 / 200 / 250 / 300 / 350 / 400 → select according to vessel drawing, rope path, and installation space.

• Roller Arrangement: Two rollers → suitable for standard shipside rope direction control without a closed upper frame.

• Material: Cast roller material and steel structure material to be confirmed → final material follows order specification and applicable standard requirement.

• Installation: Shipside / bulwark / deck-edge position → local hull reinforcement and mounting details should be confirmed by drawing.

• Surface Treatment: Blasting and shop primer as common marine practice → final coating, galvanizing, or polishing follows customer requirement.

• Certificate Requirement: Available according to order scope → class inspection and certificate level should be confirmed before quotation.

How It Works

Mooring rope approaches the shipside fairlead → Rope enters the open two-roller arrangement → Rotating cast rollers guide the rope path → Contact friction against ship structure is reduced → Local force is transferred through the fairlead mounting structure to the ship hull structure

Applications

Cargo vessels | Bulk carriers | Tankers | Container vessels | Tugboats | Workboats | Barges | Shipside mooring stations | Bulwark rope guidance | Newbuilding and replacement projects

Certifications & Advantages

FAQ

Q1: What is the difference between AF and AS in JIS F 2014 open type two-roller fairleads?

A1: AF is the open type two-roller fairlead with cast rollers, while AS is the open type two-roller fairlead with steel plate fabricated rollers. The correct type should follow the vessel drawing and project specification.

Q2: Can the reference rope diameter in the table be used as SWL or MBL?

A2: No. The rope diameter values are selection references from the standard table. They should not be written as product SWL, MBL, breaking load, or test load. Load approval should be checked according to the vessel mooring design and project requirement.

Q3: What information is needed before quotation?

A3: Confirm JIS F 2014 AF type, nominal size, rope diameter, material, surface treatment, quantity, installation drawing, certificate requirement, delivery destination, and required delivery time.
