How to use this calculator

  1. Collect the values below from the equipment nameplate, data sheet, or field measurement.
  2. Enter values using one consistent unit system and use worst-case operating conditions.
  3. Review the result, margin, and engineering note before selecting hardware.
  4. Cross-check the result with the related calculator and save the review for your project record.

Input checklist

Example field question

Use this calculator when a design review or site issue requires a quick engineering check before a detailed manufacturer selection.

Common mistakes to avoid

Do not mix nominal values with measured worst-case values. Keep units consistent and include cable, temperature, duty, and derating assumptions where applicable.

Standards and validation

Review the result against local codes, IEC/NEC/NFPA/ISO practices when applicable, project specifications, and the latest manufacturer data sheet.

Recommended workflow

Start with the primary calculation, then use the related tool to check the next design dependency. Save or print the result only after the assumptions and worst-case conditions are confirmed.

Formula and Inputs

Minimum bending radius is estimated from cable outer diameter and the manufacturer’s static or dynamic bend-radius multiplier.

Industrial Use Cases

Use this page for robot dress packs, machine tools, linear axes, cable carriers, and repeated flexing applications.

Engineering Note

Always use the cable manufacturer’s dynamic rating. Check travel speed, acceleration, torsion, unsupported length, separation, and carrier fill.

FAQ

Is static bend radius suitable for a drag chain?

No. Moving applications require the manufacturer’s dynamic bend radius and cycle-life rating.

How much free space should a cable carrier have?

Leave enough clearance for movement and heat, and follow the carrier and cable manufacturer’s fill and separation guidance.

Preliminary engineering reference only. Confirm final selections against current standards, project specifications, and manufacturer data.
