Short answer
Inspect your cables before each use as your manual says, stop using the machine if a cable or fitting is damaged, and replace it with the machine maker's own part. Replacement intervals are product-specific: follow your maker's, and ask the maker if the manual gives none.

What makers tell owners
| Maker | What the document says |
|---|---|
| Body-Solid (SPRFT manual) | Check the unit and its cables before each use; make sure fasteners and cables are secure and in good working condition[1] |
| Body-Solid (SPRFT manual) | Use only Body-Solid replacement parts; return damaged or dropped equipment to a service center[1] |
| Bowflex (Xtreme 2 SE assembly manual) | Use only genuine Nautilus replacement parts and hardware[2] |
| Precor (general safety text) | Cables should be secured at both end connections and properly threaded; keep equipment needing service out of use until repaired[3] |
| Inspire (safety policy) | Inspect cables, nuts, bolts and belts; repair or replace damaged parts at the first sign of a problem[4] |
| Decathlon (weight training pulley) | Change the cable at least once a year as a wearing part[5] |
Each row applies to that maker's equipment. Decathlon's yearly rule is for its pulley, not a rule for every machine. Body-Solid's SPRFT manual gives no replacement interval or wear criteria.[1] The Precor document we read is an assembly guide with a general safety excerpt, and its readable text gives no inspection interval.[3]
When to stop
If you see damage, stop. That includes a cable that is not secured at both ends or is off its pulley, which Precor's text covers directly.[3] For a cracked coating or anything else that looks wrong, Inspire's rule applies: repair or replace at the first sign of a problem.[4] Body-Solid goes further for damaged or dropped equipment and says to return it to a service center.[1]
The ball at the end of the cable
Many cables end in a stop that keeps the cable from pulling back through the pulleys. Bowflex calls it the "Cable End Stop Ball". Its Xtreme 2 SE assembly manual tells the assembler to fit the ball's core over the cable ferrule so the cable cannot slip back through the pulleys.[2] That manual has no inspection guidance; it points to the owner's manual for maintenance.
What a gym cable is made of
- Coating. Lexco describes PVC, vinyl and nylon coatings as a jacket over the cable.[6] The coating is not the cable itself.
- Construction. Lexco uses 7x7 and 7x19 as aircraft-cable strand constructions, typically from 1/32 to 3/8 in diameter.[6] That is industrial terminology, not a gym-cable specification.
- Wire size. Certex says smaller wires improve a rope's bending-fatigue performance, while large outer wires and an independent wire rope core give better crush resistance.[7] That is industrial rope-selection guidance, offered here as background only.
Why you order the maker's part
End fittings come in many forms. One UK gym-parts retailer lists swage end studs in several metric and imperial threads, including M6, M8 and M10, in right- and left-hand versions, plus snap hooks, threaded hex bolts and swivel ends.[8] With that many variants, matching a fitting by eye is guesswork. The maker's part number removes it.
Do not make, shorten or rebuild a cable yourself.
When the manual is hard to find
Some manuals are not easy to read online. True Fitness lists the SPL-0500 manual in its user-manual directory, at revision REV09.[9] We could not read its cable guidance, so we do not summarize it. Ask the maker for the current manual and the part number for your cable.

Questions
How often should I replace a gym cable?
As your machine's maker states. Decathlon says to change its weight training pulley's cable at least once a year as a wearing part, but that rule is for its product; Body-Solid's SPRFT manual gives no replacement interval.[5][1]
Can I use a generic replacement cable?
Use the maker's part. Body-Solid says to use only Body-Solid replacement parts, and Bowflex says to use only genuine Nautilus replacement parts and hardware.[1][2]
What is the ball on the end of my cable?
On the Bowflex Xtreme 2 SE it is the Cable End Stop Ball. The assembly manual says its core fits over the cable ferrule so the cable cannot slip back through the pulleys.[2]
