High-performance springs for pressurized systems
Proven expertise in the hydraulic sector
For more than 60 years, Ressorts Dury has been the reference partner for hydraulic equipment manufacturers. Our expertise in the design and manufacture of technical springs allows us to meet the specific requirements of this demanding sector.
Our springs equip essential components: cylinders, distributors, pumps, accumulators, safety valves and pressure regulators. Wherever reliability under stress is an absolute requirement.
Quality requirements adapted to hydraulic sector standards
The hydraulic equipment sector demands flawless reliability and resistance to extreme pressures. At Ressorts Dury, we meet these requirements through:
- A complete traceability of raw materials and every production stage
- Rigorous controls: dimensional, load, sealing, fatigue and corrosion resistance
- With certified processes compliant with industrial standards (ISO 9001)
- Complete technical documentation (material certificates, inspection reports, definition drawings)
Materials and treatments adapted to hydraulic constraints
We master the processing of a wide range of high-performance materials adapted to hydraulic environments:
- Chrome-vanadium alloy steels – high fatigue resistance and dynamic pressure resistance
- Stainless steels (302, 316, 17-7 PH) – excellent corrosion and moisture resistance
- Copper alloys and bronze – compatibility with specific hydraulic fluids
- High yield strength steels – for repeated cycles under high pressure
Each spring benefits from adapted heat and surface treatments (shot peening, passivation, anti-corrosion coatings) ensuring optimal service life against high pressures, vibrations and aggressive fluids.
