Norgren RM/91032/M/25 Pneumatic Cylinder - Magnetic
Part Number: RM/91032/M/25
Quick Summary
Norgren RM/91032/M/25 is a compact single-acting pneumatic cylinder for space‑constrained automation in packaging and assembly lines. In tight spaces, traditional cylinders can slow cycles and increase downtime due to wear and misalignment. The design emphasizes a low-friction seal, non-corrodible construction, and a magnetic piston to support reliable operation within CE/ISO frameworks and industrial environments. These features deliver space efficiency, predictable performance, and lower lifecycle costs while enabling straightforward integration with standard G1/8 fittings and Pneufit components.

Feature: 32 mm bore and 25 mm stroke with operating pressure 2 to 10 bar; single-acting operation. Business Impact: Delivers compact footprint without sacrificing push force, enabling faster cycles in tight-machine layouts. Application: Suitable for clamp, pick-and-place, and fixture actuation where space is at a premium and consistent force is required. Feature: Magnetic piston and standard non-corrodible construction; anodised aluminium barrel and stainless steel rod. Business Impact: Enhances sensing reliability and longevity in challenging environments, reducing maintenance and downtime. Application: Ideal for automation cells with position sensing needs and frequent actuation cycles. Feature: Theoretical force of 432 N; no cushioning. Business Impact: Provides strong, predictable actuation for moderate-load tasks; no internal damping means simpler integration with external stops and control logic. Application: Common in automated transfer lines and gripping stages where crisp return is desired. Feature: One third the basic length relative to ISO/VDMA models. Business Impact: Maximizes throughput per footprint, lowering machine height and enclosure space. Application: Retrofit projects and retrofit-friendly installations where height is constrained. Feature: Port size G1/8 and inclusions for Pneufit C fittings; mounting options include Nut style N2, front/rear flange, piston rod clevis, and stud/adaptor mounts. Business Impact: Simplifies install, reduces auxiliary hardware, and supports rapid configuration for different end-effectors. Application: Widely compatible with standard pneumatic manifolds and line-maintenance routines, reducing commissioning time.

FAQs
RM/91032/M/25 supports multiple mounting configurations: front/rear flange mounting (32 mm bore), nut style N2 (M/P1501/60), piston rod clevis (20 mm bore, QM/57020/25), and stud/adaptor mounting (M/P1710/22). This range lets you align load direction with machine movement while preserving stroke and actuator alignment, reducing misfit risk and simplifying installation in confined spaces.
The cylinder features a 32 mm bore, 25 mm stroke, and operates between 2 and 10 bar. Theoretical force is 432 N, which supports reliable actuation for moderate loads. In practice, cycle time scales with supply pressure, load, and end-of-stroke timing. For faster cycles, maintain adequate pressure and minimize external cushioning requirements while ensuring smooth starts and stops.
Yes, this model aligns with Pneufit C push-in fittings and 6 mm tubing for G1/8 ports. Included fittings listed in the data set include C0L510618 (Push-in fitting with Banjo flow control), C02250618 (Adaptor), and C02470618 (90° elbow). For best reliability, pair with compatible Pneufit C components and plan for a complete porting kit that matches your manifold layout.
The data does not explicitly list certifications like CE, IP, or SIL for RM/91032/M/25. For regulated applications, confirm with Norgren or your distributor that the specific lot meets your required standards (CE marking, IP rating, and SIL compatibility if needed). This ensures traceability and alignment with your plant's compliance program.
The combination of a low-friction, long-life seal design, non-corrodible barrel, and a magnetic piston enhances reliability and reduces wear-related downtime. The 32 mm bore and 25 mm stroke deliver strong, predictable actuation without external cushions, while a compact footprint saves space. Together these features lower maintenance costs, shorten downtime, and boost overall line productivity.
