Equipment Used In‑House or By Our Partners
- Precision barrel honing systems

- Pneumatic leak/pressure test benches up to 150 psi (10 bar)
- CNC lathes & mills for custom component fabrication
- Dedicated fixtures/jigs for alignment & assembly
We Coordinate Repairs For All Cylinder Types
- Single‑acting & double‑acting cylinders
- Round‑body & NFPA tie‑rod styles
- ISO 15552 metric-profile cylinders
- Compact, guided, and custom actuators
- Obsolete or unsupported OEM models (reverse‑engineered)
Design for Serviceability (DFM)
- Share bore, rod diameter, stroke, mounting style, and port sizes; photos with a ruler help.
- Flag critical surfaces: rod finish (typically 8–16 µin Ra) and bore condition after honing.
- Confirm operating pressure (usually 80–120 psi) & any cushion/position-sensing needs.
- Use standard mount styles (clevis, flange, trunnion) for ISO/NFPA interchangeability.
- If rod is bent/scored, replate & grind or replace; over‑tight seals increase friction & wear.
We’ll confirm achievable specs and the best routing (in‑house or partner) before kickoff.
