When sourcing replacement gym cables, most buyers focus on the wire rope itself —the diameter, the coating, the flexibility. But the end-fittings are equally critical. They determine whether the cable physically fits your machine, how safely it connects under load, and how easy it is for gym staff to replace.
At Yongrui, we supply fully assembled cable solutions with 60+ accessory SKUs —from bare wire rope to factory-swaged, pull-tested, ready-to-install assemblies. This guide walks you through every decision you need to make.
1. Common End-Fitting Types
The right terminal depends on how the cable connects to the weight stack, handle, or anchor point on your specific machine. Here are the four primary categories:
Not sure which fitting your machine uses? Send us a photo of the existing cable end and the machine model number. Our engineers will identify the exact fitting type and provide a matched replacement spec —free of charge.

3. Why Professional Swaging is Non-Negotiable
In a commercial gym environment, an end-fitting failure is not a maintenance issue —it's a safety incident. A cable under a 200 lb weight stack that pulls free of its fitting can cause serious injury.
What is Hydraulic Swaging?
Swaging is the process of cold-deforming a metal ferrule or fitting around the cable wires using high-pressure hydraulic force —typically 50—00 tons. This creates a permanent, mechanical bond between the fitting and the wire strands that is stronger than the wire itself.
A crimped or clamped fitting (the type sold in hardware stores) relies on friction only. Under repeated load cycling, the clamp loosens. A swaged fitting does not.
Our Quality Control Process
- Hydraulic swaging press —calibrated to the wire diameter and fitting material for consistent compression
- 100% pull-testing —every batch is destructively tested to verify the terminal holds beyond the rated break load
- Visual inspection —coating continuity check at the fitting junction to prevent moisture ingress
- Documentation —test certificates available for OEM customers and quality audits
Never use DIY cable clamps (U-bolt clamps or wire rope clips) on gym equipment. They are designed for static loads only. Gym cables experience dynamic shock loads on every rep —only swaged terminals are appropriate for this application.
4. How to Measure for a Custom Cable Order
To generate an accurate quote and ensure a perfect fit, provide these three measurements:
Total Assembly Length
Measure bearing point to bearing point —from the center of the eyelet hole (or the base of the ball shank) on one end, to the same reference point on the other end. Do not measure from tip to tip of the fittings. Example: 1,850 mm BTP
Cable Diameter —Two Numbers Required
Specify both the steel core diameter and the finished OD after coating. These are different. Example: Ø3.18mm core / Ø4.76mm OD (Nylon coated). If you only have the finished OD, our team can back-calculate the core size.
Fitting Specifications
For eyelets: the bolt hole diameter (e.g., 10mm hole for M10 bolt). For ball shanks: the ball diameter and shank length. For threaded studs: the thread size and engagement length. A photo of the existing fitting with a ruler is always helpful.
Send us a clear photo of the old cable next to a ruler, plus your machine brand and model. Our engineering team can identify the specification from photos alone for most major brands (Life Fitness, Technogym, Precor, Matrix). Submit a photo inquiry →
