Compact Form Factor and Power Density: The RM/92025/N4/30 features a 25 mm bore and 30 mm stroke, delivering a compact actuator footprint that frees space in control panels and on crowded automation lines. Its shorter length compared with ISO/VDMA equivalents directly translates to easier machine integration, faster cycle times, and reduced enclosure size. In practice, this means more efficient layouts for pick-and-place and clamping applications, with less need for extraneous mounting hardware. The business impact is lower upfront enclosure costs and improved line throughput in high-density systems.Rugged Materials for Longevity: The anodised aluminium barrel paired with a stainless steel piston rod provides robust corrosion resistance and durability in harsh plant environments. This combination reduces maintenance intervals and replacement costs while maintaining consistent performance across a wide operating temperature range (-5 to 80 °C). The resulting uptime supports industries such as food & beverage, packaging, and automotive assembly, where reliability is non-negotiable and downtime is costly.Control-Ready Sensing: A standard magnetic piston enables straightforward integration with position sensors and control logic, minimizing additional components and wiring. This design choice simplifies installation in automated cells and enables accurate feedback for closed-loop control without custom sensing solutions, enhancing predictability and reducing commissioning time.Pressure and Force Alignment: Rated for 1–10 bar with a theoretical 295 N thrust, the RM/92025/N4/30 aligns with typical factory air systems and task-specific load requirements. The low-friction, long-life seal design reduces stick-slip and wear, contributing to smoother cycling and lower energy losses during actuation. For OEMs, this translates into improved component life and reduced total cost of ownership over the product lifecycle.Installation and Compatibility Advantage: The M5 port size supports common valve and manifold configurations, while the compact form factor eases retrofits into existing equipment. The model sits within the RM/92000/M range, offering a familiar platform for designers who value consistency across pneumatic cylinders and easier spare-part planning, stocking, and maintenance.

FAQs
This cylinder uses an M5 port and a compact 25 mm bore, designed for straightforward mounting in tight spaces. Its smooth, corrosion-resistant anodised aluminium barrel and stainless steel piston rod simplify integration with standard valve manifolds and sensor plates. When retrofitting, verify clearance for the 30 mm stroke and ensure adequate end-of-stroke sensing so control logic captures accurate position feedback.
Operating between 1 and 10 bar, the RM/92025/N4/30 delivers a theoretical force up to 295 N, supporting efficient linear actuation in common automation tasks. The unit uses low-friction, long-life seals to minimize wear and stick-slip, enabling repeatable cycles. For high-speed applications, ensure cushioning is considered, as this model specifies no cushioning, which affects impact and cycle dynamics.
The extended description notes the cylinder’s compact form relative to ISO/VDMA models, indicating favorable compatibility in space-constrained layouts while leveraging standard pneumatic interfaces like M5 ports. For OEM assemblies, plan around the RM/92000/M range’s common mounting patterns and ensure control hardware can accommodate a magnetic piston for streamlined sensing.
Durability comes from an anodised aluminium barrel and a stainless steel (austenitic) piston rod, both chosen for corrosion resistance and long life under varied temperatures (-5 to 80 °C). The standard magnetic piston further supports reliable sensing and control, reducing the need for added sensors and minimizing maintenance overhead in dusty or humid environments.
Best suited for space-constrained pick-and-place, clamping, and linear actuation tasks on manufacturing lines, packaging equipment, and automation pockets. The compact length and 25 mm bore enable tighter line layouts, while the durable construction lowers maintenance frequency. The magnetic piston supports straightforward integration with control systems, contributing to faster commissioning and improved line throughput over the cylinder’s lifecycle.
