We machine production parts for Fitness and Gym Equipment customers, from single prototypes through to repeat batches of tens of thousands. Typical work covers weight stack plates, pivot arms and adjustment pins, usually in 1045 or 4140.
What makes Fitness and Gym Equipment different from general machining is not the geometry — it is the documentation and the failure modes. The parts that come back are the ones where static safety testing is mandatory — a failure is a liability event was not designed out at the start.

Standards and documentation
- EN 957 for stationary training equipment, ASTM F2216
Tell us which standard applies and which documents you need with the shipment. Dimensional reports, material certificates, certificates of conformity and first article inspection reports are all available, and it is much cheaper to agree them before the batch runs than to reconstruct them afterwards.
Where Fitness and Gym Equipment projects usually go wrong
- Static safety testing is mandatory — a failure is a liability event
- Cosmetic wear from constant handling

Frequently asked questions
Do you have experience with Fitness and Gym Equipment parts?
Yes. Typical parts we run are weight stack plates and pivot arms. We can share the process route and inspection approach for a comparable part before you commit.
Which materials do you recommend for Fitness and Gym Equipment?
1045, 4140, Aluminium, Nylon. The right choice depends on which of corrosion, weight, strength and cost is the binding constraint, and we will say so plainly rather than quoting the most expensive option.
What documentation do you provide?
A dimensional report and a certificate of conformity as standard. Material certificates, CMM reports, FAIR and PPAP submissions are available when your quality system requires them.
What tolerances do you hold for Fitness and Gym Equipment parts?
+/-0.1 mm general; H7 on pivot bores with Ra 0.8 um is typical for the industry. Tighter tolerance on individual features is possible and is quoted against the specific feature rather than the whole part.
