Norgren QM/748 Mounting Interface - RM/900 Style C
Part Number: QM/748
Quick Summary
QM/748 is a mounting interface that secures RM/900 Style C components in compact pneumatic systems. Engineers often struggle with misalignment, leakage, and downtime when mounting actuators in confined spaces. The solution supports CE compliance, IP-rated robustness, and SIL-capable safety integration, helping you meet regulatory requirements without sacrificing performance. By simplifying fixture geometry and providing clear mounting dimensions, the QM/748 reduces commissioning time and improves reliability. The 2.5 inch footprint aligns with common RM/900 installations, while CAD assets and datasheets accelerate design-in and procurement. In practice, teams benefit from faster starts, easier maintenance, and lower total cost of ownership on automation lines.

IMI Norgren
Designed specifically for the RM/900 range, the QM/748 uses a precise 2.5 inch mounting footprint that aligns with Style C mountings. This tight tolerance minimizes misalignment during actuator installation, reducing commissioning time and the need for on-site shimming in new builds or retrofits. Access to CAD assets and the official RM 900 datasheet streamlines engineering workflows by enabling digital twins and accurate BOMs. Engineers can drop the QM/748 into assemblies with minimal modification, speeding procurement and cutting design-to-build cycles. The mounting interface is designed to resist vibration and maintain a consistent alignment under dynamic loads, improving actuation reliability and reducing seal wear in high-cycle applications. Standardized form factor across Norgren/Martonair lines simplifies stocking and spares planning, while quick installation reduces field labor and downtime. In practice, teams report lower maintenance intervals and improved asset availability when replacing legacy adapters with QM/748, especially in OEM and system integrator environments. The result is clearer documentation, faster design-in, and a tangible reduction in total cost of ownership for automation projects.

FAQs
QM/748 is designed to attach directly to RM/900 Style C mounting interfaces. Begin by aligning the 2.5 inch footprint with the actuator boss, insert the fasteners, and torque to the manufacturer’s specification. Use the CAD drawing to verify hole alignment and clearance, then perform a light functional check to confirm proper seating and sealing before operation. This approach minimizes rework and ensures repeatable assembly across production lines.
Key specs include RM/900 Range compatibility, Martonair Series, and a 2.5 inch mounting footprint. These factors contribute to precise alignment, reduced installation time, and predictable performance in compact pneumatic systems. The standardized interface also supports quick cross-referencing in BOMs, simplifies spares management, and improves overall system reliability in high-cycle automation environments.
Yes. QM/748 is specifically designed to support RM/900 Style C mountings in Martonair actuator assemblies. Its alignment precision, documented mounting dimensions, and access to CAD assets make it ideal for OEM equipment builds, system integration projects, and retrofit applications where space is tight and reliability is critical.
Key standards to consider include CE compliance for electrical and safety conformity, IP ratings related to enclosure protection, and SIL considerations for safety-integrated automation. While the QM/748 supports these common regulatory and safety frameworks, always verify your specific installation’s environmental and risk requirements with the system designer and applicable regional regulations.
The QM/748 reduces commissioning time and field labor due to its standardized mounting footprint and available CAD assets, which lowers design-to-build cycles. Improved alignment stability decreases wear and leakage concerns, extending actuator life and reducing maintenance costs. OEMs and integrators typically see faster time-to-market and higher asset availability, delivering a favorable ROI over the life of the equipment.
