Control cable technical guide
Essentials for selecting, installing and maintaining push-pull control cables.
Choosing the right cable
Define your application's requirements up front:
- Overall length and stroke
- Required push and/or pull force
- Number of bends and bend radii along the route
- Operating temperature and environment (dust, humidity, oil, salt water)
- End fitting types and dimensions at both ends
- Expected duty cycle and service life
Routing and bends
A cable's efficiency and life depend largely on its routing.
- Keep the route as straight and short as possible
- Avoid sharp bends; use large bend radii
- As total bend angle increases, operating force rises and precision drops
- Route the cable so it cannot be pinched between moving parts
- Keep it away from exhausts and other heat sources
Installation
Correct installation lets the cable deliver its catalog performance in the field.
- Secure the conduit firmly at both ends
- Align end fittings with the axis of motion
- Make sure the inner core is not overstressed at the end of stroke
- Do not use clamps that crush or kink the conduit
- After installation, check for free movement over the full stroke
Maintenance and replacement
Regular inspection prevents unexpected failures.
- Stiffening or increased backlash means it is time to replace
- Check the conduit for cracks, crushing or corrosion
- Check end fittings for wear and looseness
- When replacing, send us the old cable's code and dimensions
