Norgren MC600MH2 Shock Absorbers - 25 million cycles
Part Number: MC600MH2
Quick Summary
Norgren MC600MH2 shock absorbers provide maintenance-free damping for pneumatic cylinder end covers in automated lines. Engineers often battle wear, rod fatigue, and downtime from frequent maintenance; these units are designed for long service life and predictable performance. Industry-standard considerations for these components typically include CE marking and IP ratings for rugged environments, with SIL qualifications pursued in safety-critical lines. By enabling direct end-cover mounting on cylinders up to 7 bar and featuring a steel body with a black oxide finish, they simplify installation, reduce parts inventory, and support lean manufacturing while improving uptime and overall equipment effectiveness.

Maintenance-free, self-contained hydraulic damping delivers durable performance without regular lubrication or seal maintenance. The MC600MH2 achieves up to 25 million cycles, providing a stable damping curve across extended production runs. In automated packaging and assembly lines, this translates to reduced maintenance windows, lower spare-parts consumption, and higher overall equipment effectiveness. Extremely low rod return force reduces mechanical stress on cylinders and guides, improving precision and extending component life. The softened rebound minimizes vibration transfer to upstream equipment and lowers energy use by requiring less actuation force to retract, supporting higher line speeds without sacrificing control. Direct mounting into the end cover of pneumatic cylinders (up to 7 bar) simplifies retrofits and minimizes space requirements. This compatibility enables compact machine designs, faster installation, and lower integration risk in retrofit projects, while the steel body with black oxide finish withstands harsh environments. Integral positive stop on all models provides a repeatable end-of-stroke position, reducing overshoot and maintaining consistent damping across cycles. This feature helps meet tight motion tolerances in packaging and precision assembly, boosting repeatability and process reliability. Operating range and compatibility: operating temperature 0–66 °C and effective weight range 400–2300 kg guide proper selection for typical automation loads. As part of the MC Ace series from IMI Norgren, it aligns with a modular, rugged damping portfolio designed for maintenance-friendly integration in modern factories.

FAQs
Install by aligning with the cylinder end cover and mounting directly into the end cover up to 7 bar. Ensure the unit supports the system’s load range (400–2300 kg) and observe the integral positive stop for repeatable strokes. Use standard mounting hardware and verify clearances to avoid binding or contact with moving parts.
The MC600MH2 is designed for maintenance-free operation with a life expectancy up to 25 million cycles. It provides extremely low rod return force for smooth deceleration, reducing wear on cylinders and guides and supporting stable positioning across long production runs.
Yes. The MC600MH2 is part of the MC range within the Ace series and supports direct end-cover mounting on pneumatic cylinders (up to 7 bar). This simplifies retrofits, minimizes space requirements, and integrates with standard Norgren components for reliable damping in tight spaces.
No. It uses maintenance-free, self-contained hydraulic components that do not require regular lubrication or seal replacement. Routine inspections are still recommended to verify mounting integrity and operating conditions, but there’s no ongoing lubrication schedule.
High-cycle automation such as packaging, pick-and-place, and precision assembly benefit most. The combination of up to 25 million cycles, low rod return force, and direct end-cover mounting supports long uptime, high repeatability, and streamlined installation in rugged industrial environments.
