Design Considerations:
CMA’s Cycle-Flex is recommended for rigorous, high cycle life cable applications. It is a lubricated stainless steel strand coated with a very flexible, abrasion resistant nylon.
- Depending upon load consideration cable stretch, both constructional and elastic, needs to be considered. Constructional stretch can be removed; elastic stretch can be calculated.
- Based upon the application, select the desired cable construction. For example, 1×7 is the stiffest while 7×19 is the most flexible.
- Determine what the cable and assembly breaking strength needs to be based upon the working load plus a safety factor.
- If pulleys or capstans are involved in your design, they must be of a suitable size. For example, for 7×19 cable construction, the pulley diameter needs to be 24 times the diameter of the cable.
- Remember that the cable assembly strength will usually be less than the tensile strength of the cable.
- Based upon item 3, 4 and 5, determine the cable diameter to be used.
- Determine the type of end fitting that will be required for attachment of the cable for your particular application. Our Design Engineers can help with this selection.
- For best holding strength, it is necessary to strip the coating prior to applying the end fittings. The design should allow for this.
- Consider cable assembly tolerances. Cables are flexible entities and not suitable for very tight length tolerances.
