FAQs
MC225M units are designed for direct mounting in the end cover of compatible pneumatic cylinders, up to 7 bar. Begin by verifying cylinder bore and end-cap compatibility, then align the damper axis with the piston rod to ensure stable engagement. Tighten mounting hardware to the manufacturer’s torque specification, install any protective guards as needed, and cycle test to confirm smooth operation and the effectiveness of the integral stop.
Yes. MC225M is part of the MC range and Ace series, which ensures consistent interface standards and ready compatibility with other Norgren components. When selecting complementary dampers or mounting accessories, reference the MC series profile to maintain alignment with module spacing, mounting threads, and end-cover interfaces. This compatibility simplifies parts stocking and reduces integration risk in retrofit projects.
MC225M operates from 0 to 66 degrees Celsius (32 to 150.8 °F). It supports an effective weight range of 2.3 to 25 kg, making it suitable for a wide spectrum of pneumatic actuators and end-to-end damping requirements in industrial environments without over-sizing.
The MC225M offers a cycle life of up to 25 million cycles, delivering extended service life in high-cycle automation applications. This durability translates into reduced maintenance intervals, lower spare-part consumption, and improved equipment availability across continuous or high-throughput production lines.
Ideal for applications requiring precise end-stop damping and long-term reliability, such as automated packaging, clamping, and assembly lines. The ability to mount directly on the end cover of cylinders up to 7 bar, combined with a positive-stop feature, makes it well-suited for repeated stroke control, reduced shock loads, and safer, repeatable positioning in harsh manufacturing environments.
