Design & Material Specifications
| Type | Wave‑spring design (coiled undulating ring) for compact axial space |
|---|---|
| Application | Used to apply axial force in assemblies, maintain bearing or seal preload, resist loss of tension under vibration and cyclic movement |
| Material & Finish | High‑quality spring alloy engineered for fatigue resistance and fluid‑exposure durability |
| Operational Environment | Designed for spray foam, polyurea, high‑pressure fluid delivery systems operating under repeated cycles, pressure fluctuations and mechanical shocks |
| OEM Quality | Manufactured to Graco’s original specifications to ensure proper fit and consistent performance in Graco equipment |
Installation & Maintenance Guidelines
• Confirm the correct wave spring (part number 105364) is specified for your machine and assembly.
• Depressurize and disconnect the system before disassembly.
• Ensure the seating surface is clean, flat and undamaged before installing the spring.
• Install the spring in the correct orientation and ensure full seating around the circumference.
• At each service interval, inspect the spring for visible fatigue, deformation or corrosion—replace if any signs are present.
Using the authentic Graco 105364 Spring, Wave helps preserve the mechanical alignment and functional integrity of your Graco spray and foam equipment.
User Application & Field Insights
- Favoured in high‑cycle spray foam machines where axial load must remain steady over thousands of operations.
- Often replaced during preventive maintenance to avoid failure of preload elements and subsequent seal or bearing issues.
- Stocking an OEM wave spring reduces downtime associated with unexpected spring failure in critical fluid‑handling systems.
- Genuine parts maintain system manufacturer‑design performance, minimizing the risk of mechanical alignment issues or premature wear.
In short, the Graco 105364 Spring, Wave is a compact, high‑performance spring designed to support reliable operation, stable preload and long‑term durability in professional Graco equipment.
