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

Factors to Consider When Selecting Core Type

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
