Quick Summary

Norgren MC225MH2 shock absorbers provide maintenance-free damping for pneumatic cylinders used in automation systems. In high-cycle environments, traditional dampers can demand frequent servicing and jeopardize line uptime. Certification considerations vary by region, but many Norgren designs align with CE compliance, IP-rated configurations, and SIL safety concepts where applicable to control integration. This approach supports OEMs in standardizing parts across multiple lines, delivering reliable damping while reducing total cost of ownership and downtime.

Feature: Maintenance-free, self-contained hydraulic components. Benefit: Reduces routine servicing and lubricant scheduling, improving uptime and predictability in automated presses and pick-and-place cells. Application: Suitable for continuous operation in manufacturing lines where minimal maintenance is desired and service windows are limited. The integrated design also simplifies inventory management, enabling faster changeovers and less on-site handling. Feature: Up to 25 million cycles lifespan. Benefit: Delivers superior fatigue resistance and longer service life in high-frequency cycles, lowering replacement frequency and spare-parts costs. Application: Ideal for high-volume transfer systems and robotic actuators with repetitive motion where reliability is critical. Industry context: supports lean production goals by minimizing unplanned downtime. Feature: Extremely low rod return force. Benefit: Reduces mechanical stress on cylinders and guiding components, extending equipment life and easing actuation force requirements. Application: Particularly advantageous for high-speed positioning stages and delicate tooling operations where abrupt returns cause wear. Feature: Direct mounting into end covers (up to 7 bar). Benefit: Streamlines installation by eliminating intermediary brackets, reducing assembly time and potential misalignment. Application: OEMs can retrofit existing cylinders quickly, enabling rapid deployment across lines. Feature: Integral positive stop. Benefit: Provides a guaranteed soft stop at end-of-travel, enhancing cycle consistency and protecting system columns from over-travel damage. Application: Critical in precision batching and press-form applications where repeatable stopping is essential. Feature: Robust body and range details (steel with black oxide finish; MC range; Ace series). Benefit: Combines durability with corrosion resistance in harsh factory environments, ensuring reliable performance in temperature 0–66 °C. Application: Suitable for general industrial automation tasks, including transfer and clamp routines, with consistent results across multiple cylinders.

FAQs

The MC225MH2 is designed for direct mounting into the end cover of pneumatic cylinders up to 7 bar, simplifying installation and reducing the need for additional mounting hardware. This direct-mount capability minimizes misalignment and accelerates retrofits on existing lines, which is especially beneficial for OEMs updating legacy equipment.
MC225MH2 uses maintenance-free, self-contained hydraulic components to deliver a long service life. No periodic lubrication is required, reducing maintenance intervals and downtime. The design emphasizes fatigue resistance and consistent damping over millions of cycles, making it suitable for high-demand production environments.
Yes, the product targets a broad effective weight range of 180–910 kg, supporting demanding load profiles. Built with steel bodies and a black oxide finish, it provides durability in production environments while maintaining reliable damping across temperatures from 0 to 66 °C.
Certification specifics depend on region and installation. While data for this model lists general compliance considerations, buyers should verify CE conformity, IP-rated configurations, and SIL compatibility with downstream safety controls for each application to ensure regulatory alignment.
The combination of maintenance-free operation, up to 25 million cycles, and direct end-cover mounting reduces downtime, spare parts, and labor. In addition, the integral positive stop improves repeatability and protects components from over-travel, delivering lower total cost of ownership over the equipment lifecycle.
