Formula and Inputs
Minimum bending radius is estimated from cable outer diameter and the manufacturer’s static or dynamic bend-radius multiplier.
VoltCheck24 Engineering Calculator
Cable Bending Radius and Cable Carrier Calculator
Calculate minimum cable bending radius and cable-carrier clearance for moving industrial cables and drag-chain applications.
How to use this calculator
- Collect the values below from the equipment nameplate, data sheet, or field measurement.
- Enter values using one consistent unit system and use worst-case operating conditions.
- Review the result, margin, and engineering note before selecting hardware.
- Cross-check the result with the related calculator and save the review for your project record.
Input checklist
- Cable outside diameter
- Dynamic bend-radius multiplier
- Travel stroke and speed
- Carrier fill and separation
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.
