How to Select the Right Inner Wire Core for Mechanical Control
Cables
Choosing the correct strand configuration for your inner wire core
is critical for ensuring optimal cable performance, durability, and
user experience. At Phidix, we help engineers, designers, and OEMs align cable core
structures with specific mechanical, spatial, and environmental
demands.
This guide will walk you through the pros, cons, and ideal uses for
each major construction type.
Strand Configuration Comparison Table
Construction | Flexibility | Push Performance | Bend Radius | Application Suitability |
1x7 | Low | Excellent | Large | Long straight runs, rigid cable routing |
1x19 | Medium | Very Good | Medium | Precision push-pull actuation |
7x7 | High | Medium | Tight | Versatile routing, good tensile/flex combo |
7x19 | Very High | Lower | Very Tight | High-flex routing, complex motion paths |
Solid Core | None | Best | Rigid only | Short travel, direct motion transfer |
Factors to Consider When Selecting Core Type
1. Routing Complexity
• Tight bends or curves → prefer 7x19 or 7x7
• Straight, fixed paths → 1x7 or solid core
2. Motion Type
• Pure push or pull → solid core or 1x19
• Repetitive flexing → 7x19 preferred
3. Force Transfer Priority
• Higher compressive stiffness → solid or 1x7
• Balanced tension + flex → 7x7
4. Environment
• High corrosion risk → Choose SUS 316L options
• Friction-sensitive systems → Use PTFE-coated 1x19 or 7x7
Application Scenarios & Structure Fit
Application | Recommended Core Type(s) |
Motorcycle Throttle Cable | 1x19 / 7x7 |
Marine Control Levers | 7x7 / 7x19 |
Industrial Damper Actuators | Solid / 1x7 |
Commercial Recliner Seat Release | 7x19 |
Small Engine Choke Cables | 1x7 / 1x19 |
