Cables designed with sold wire cores are used in applications that require the transmission of forces in both the push and pull mode of operation. The vast majority of these products use various combinations of conduit styles and solid wire cores in their construction. Solid wire cores can be formed on the ends to eliminate the need to apply separate fittings or terminations. Bend radii should be large and routing must be simple in order to avoid a permanent set in the core wire.
In other cases, stiffer, small diameter stranded cables can be used for push-pull cables, providing the push load is very light and the combination of cable and conduit is carefully considered. In some applications, a reinforced stranded cable (Armored Core) can be used which offers higher load capacities but with increased flexibility. All stranded core push-pull cables typically require cable end-fittings but the routing allows for more bends between connection points.
All design considerations for push-pull cables also apply when using in combination with any of our controls. Additional cable manufacturing factors do affect the design of these products. They include the molded conduit fittings, conduit selection, assembly function and dimensions.
Recognition of these factors, combined with a practical design for the application, will result in a successful, reliable and cost-effective custom cable assembly.
Cablecraft offers a wide variety of standard cable end-fittings which simplify the design process saving you time to market and minimizing development costs. We offer both zinc die-cast fittings as well as steel fittings. Our Engineering team will also design the correct custom cable fittings to meet any unique or proprietary design requirements.
The use of these components, combined with cable specifications and technical information provided in our Engineering Resources, gives the designer flexibility in solving many unique functional problems.
Cablecraft uses only the highest quality stranded push-pull cable material to meet your unique requirements. All of our cable is “Commercial Grade” and is constructed to exact quality standards to meet all specifications for flexibility, size and minimum breaking strength.
Use our Engineering Resources to choose the right cable for your application. It will be necessary to match the correct OD of the cable with the proper ID of the conduit allowing for an acceptable amount of tolerance. Use our Control Cable Design Guide to aid you in making the proper selection.
Every control cable assembly application has unique requirements. Cablecraft offers a full line of conduit choices to meet your specific needs. Whether it’s flexible routing with good compressive strength or a more rigid application with good crush resistance, Cablecraft has the right conduit for you. Our conduits include Braided, Round Wire and Flat Wire Bowden, Long Lay and reinforced Long Lay. Optional liner materials are also offered to meet your application requirements.
Cablecraft offers both shuttle-molded and steel conduit fittings which can be combined with our standard controls and actuators to create a reliable and cost-effective push-pull cable assembly.
Prototypes are available and are an invaluable way to finalize the dimensional and tolerance requirements of any assembly. Life cycle and durability testing can also be conducted on prototypes, prior to production. Contact us to request a prototype.
You can get started by using our design considerations or you can download our Motion Control Design Guide to help analyze, define, design and specify the most appropriate push-pull cable assembly for your specific application. The Design Guide contains useful information and technical data necessary to develop a functional and effective push-pull cable assembly. Cablecraft’s Sales and Engineering departments welcome your inquiries and can assist you with your motion control cable design project.
Push applications are the most difficult to accomplish with ordinary cable assemblies because of the required column strength of the wire or cable core.
