Description
Model: HRH307 | Series: HRH | Product Line: Industrial Tools
Key Features & Benefits
-
Integrated Relief Valve: Protects the cylinder from overload damage, enhancing safety and durability.
-
External Threaded Ring: Simplifies installation and adjustment, saving time on-site.
-
Double-Action Design: Enables fast return strokes, improving cycle times and productivity.
-
Complete with GEJN Quick Couplings & Dust Caps: Ready to connect and protected from contamination.
-
Dust Wiper Seals: Minimize ingress of dirt and debris, extending cylinder life in harsh environments.
-
Advanced Surface Treatment: All components undergo gas nitriding and post-oxidation for superior corrosion resistance and off-center load capacity.
-
Certified G80 Lifting Eyes: Each cylinder is equipped with high-strength lifting rings for safe handling and positioning.
-
High-Grade Polyurethane Seals: Excellent sealing performance, wear resistance, and long-lasting reliability under high pressure.
Design
- The removable rigid saddle prevents damage to the plunger when it comes into contact with rough surfaces.
- The Swedish CEJN coupler and dust cap ensure safety throughout.
- The return pressure protection safety valve effectively prevents overpressure caused by incorrect pipeline connections.
- Dust seal, preventing external impurities from entering the interior of the cylinder and causing contamination or damage.
- Stop ring: Used to absorb off-center loads and prevent piston overtravel.
- Dust seal, preventing external impurities from entering the interior of the cylinder and causing contamination or damage.
- High-pressure seal to achieve zero internal leakage in the hydraulic system, reducing wear and extending service life.
