The RM/92025/M/40 uses a compact geometry that reduces footprint without compromising stroke or force. With a 25 mm bore and a 40 mm stroke, it fits tight automation cells while delivering up to 295 N of theoretical force under 10 bar supply. The overall dimensions—75 mm length, 40.5 mm height, and 37 mm width—facilitate installation in limited spaces and support smoother line balancing. A low-friction, long-life seal design minimizes wear and maintains consistent performance across cycles. This reduces maintenance intervals and operating costs, especially on high-cycle conveyors and pick-and-place tasks. The cylinder uses fully non-corrodible materials for extended service in challenging environments. Anodised aluminium housing and a stainless steel piston rod resist moisture, chemicals, and washdown exposure. Coupled with a magnetic piston for reliable sensing, this design supports longer life and lower maintenance in food, beverage, and medical manufacturing contexts. The magnetic piston enables straightforward integration with reed switches and sensors for robust position feedback. Standard mounting provisions and popular switch options, such as M/50 reed switches, simplify retrofits and new installations. This improves control reliability and reduces wiring complexity in automation networks. Operating between 1 and 10 bar and -5 to 80 °C covers a wide range of industrial applications. M5 port size and compatible Pneufit C fittings (C02250405, C02470405) streamline plumbing and serviceability. Multiple mounting options (front/rear flange, clevis, and adaptors) provide flexible installation and fast changeover for machine builders and maintenance teams.

FAQs
Begin by confirming a 25 mm bore, 40 mm stroke match and M5 porting. Use compatible fittings such as Pneufit C adapters (C02250405, C02470405) and choose a mounting solution from QM/57016/25, QM/90025/21, or BG flange options for 25 mm cylinders. Ensure alignment with the actuator rod and mountings to minimize side loads, then connect supply air between 1–10 bar. Finally, verify sensor compatibility if using M/50 reed switches for position feedback.
The cylinder offers a theoretical force of 295 N at standard conditions (10 bar). Real-world load handling depends on stroke, friction, and cycle rate, but the low-friction seals and robust materials support consistent push/pull within typical pick-and-place and clamping tasks. For higher loads, validate the system under your specific operating pressure and duty cycle and consider mounting and guide arrangements to minimize internal friction.
Yes, the design emphasizes durability in challenging environments. The barrel is made from anodised aluminium and the piston rod from stainless steel (austenitic), providing resistance to moisture and common cleaning agents. While the core construction supports reliability, verify your exact IP/washdown requirements with the datasheet and ensure appropriate seals and enclosure options are selected for your process.
Compatible fittings include Pneufit C adapters (C02250405 and C02470405) for easy push-in connections and 4 mm tubing. Mounting options cover piston rod clevis (QM/57016/25) and foot/mountings (QM/90025/21), plus front/rear flange configurations (BG) for 25 mm bore. Switch options such as M/50 series reed switches offer straightforward sensing integration with the magnetic piston.
The combination of a low-friction, long-life seal design and fully non-corrodible materials reduces maintenance frequency and replacement costs. The magnetic piston simplifies sensor integration, enabling reliable automated feedback and fewer downtime events. For line operators, this translates to higher uptime, easier retrofits, and lower total cost of ownership across high-volume production.
