FAQ

1. How does your hydraulic cylinder handle heat dissipation during operation?

GLPARTS hydraulic cylinders feature optimized oil flow and smooth surface finishes to reduce heat from friction. High-strength alloys and tight tolerances ensure thermal stability under high pressure. For demanding jobs, optional cooling designs help prevent overheating and seal wear.

2. What sealing technology do you use to ensure leak-free performance?

GLPARTS cylinders use a multi-stage sealing system with premium Japan NOK and US SKF seals, known for wear and temperature resistance. This ensures reliable performance and keeps leakage below 1%, even in harsh conditions.

3. Are your hydraulic cylinders suitable for high or low temperature environments?

Yes. Our cylinders operate reliably from -25°C to +80°C. For extreme climates like mines or deserts, we offer temperature-resistant seals and compatible hydraulic oils. Each unit is tested under simulated conditions to ensure long-term performance and stability.

4. What kind of after-sales support do you provide?

GLPARTS provides full after-sales support to keep your equipment running smoothly, including:

• 1-year warranty for manufacturing defects
• Free technical guidance on installation and troubleshooting
• Responsive service team for compatibility and maintenance issues
• Pre-shipment testing videos for added transparency
