Key Features of 7×19 Wire Rope
1. Strand Construction and Flexibility of 7×19 Wire Ropes
The 7×19 wire rope configuration features 7 strands, each made of 19 wires. This fine-wire design offers exceptional flexibility and is especially suited for applications requiring frequent bending or reeving over small-diameter sheaves.
2. Core and Strength Design of 7×19 Wire Ropes
This wire rope usually comes with a fiber core (FC) or independent wire rope core (IWRC). IWRC versions offer higher strength and better dimensional stability, while FC enhances pliability and makes handling easier in tight spaces.
3. Material Options and Corrosion Resistance
Manufactured from galvanized or stainless steel, 7×19 wire rope resists rust, moisture, and saltwater corrosion. Stainless steel variants are ideal for permanent rigging or exposed outdoor use on marine vessels.
4. Load Capacity and Breaking Strength of 7×19 Wire Ropes
Despite its flexibility, the rope maintains solid tensile strength and load-bearing performance. It supports moderate lifting tasks, control operations, and tension-based systems without compromising safety.
5. Applications and Use Cases
This wire rope is widely used in sailboat halyards, steering cables, lifelines, garage doors, and winch lines. Its flexibility and fine-wire construction make it suitable for dynamic loads and curved routing paths.
6. Diameter and Length Variations of 7×19 Wire Ropes
Available in sizes from 2 mm to 12 mm or more, the 7×19 wire rope can be cut to custom lengths and fitted with swaged or hand-crimped terminals, depending on rigging and mechanical requirements.
7. Spooling and Handling Characteristics
The rope handles easily due to its softness and compact construction. It spools smoothly on drums and over sheaves, reducing internal wear and prolonging service life in mechanical systems.
8. Compliance and Marine Standards
All 7×19 wire ropes meet ISO 2408 and relevant EN standards for steel wire ropes.
