Quick Summary

Norgren RM/92050/M/20 is a compact double-acting pneumatic cylinder designed for precise linear actuation in space-constrained automation tasks. Engineers often struggle with crowded layouts, limited installation depth, and shortened seal life in traditional cylinders. While specific certifications aren’t listed here, CE conformity and IP protection are common regulatory expectations in industrial actuation, with SIL considerations evaluated within control-system safety planning. This model’s magnetic piston and corrosion-resistant construction support versatile control schemes, while the compact length and robust materials deliver reliable performance, reduced downtime, and lower total cost of ownership for automated lines.

Feature: Compact form factor and 63x63x68.5 mm footprint. Benefit: Enables space-saving installation in tight machines and conveyed-line setups, reducing enclosure depth and package size while preserving stroke reach for compact automation tasks. Application: Packaging and pick-and-place cells where space is a premium and machine footprints must stay lean. Feature: 50 mm bore with 20 mm stroke delivering up to 1178 N theoretical force. Benefit: Provides predictable, repeatable actuation with sufficient drive for fast cycling and reliable positioning in medium-duty tasks. Application: Robotic grippers, clamping, and tooling in automation lines. Feature: Magnetic piston for easy sensing and control integration. Benefit: Simplifies feedback wiring and enables robust closed-loop positioning without extra sensors. Application: Sensing-integrated automation and PLC-controlled lines. Feature: Anodised aluminium barrel and stainless-steel rod for corrosion resistance and long life. Benefit: Extends service intervals in humid or dirty environments, lowering maintenance costs. Application: Food, beverage, and general manufacturing where durability matters. Feature: No cushioning by default, with multiple mounting options (flange, foot, clevis). Benefit: Improves cycle accuracy and enables flexible integration with existing mounting patterns. Application: Conveyor, transfer stations, and end-of-line stations. Feature: G1/8 port sizing and 1–10 bar operating pressure. Benefit: Broad compatibility with standard pneumatic systems and quick-change fittings, reducing hose and adapter requirements. Application: General pneumatic automation and retrofit projects. Feature: Range RM/92000/M compatibility with service kits QM/92050/00. Benefit: Streamlines maintenance with ready-to-use service components and predictable wear-part replacement. Application: Preventive maintenance programs and OEM service schedules.

FAQs

RM/92050/M/20 supports multiple mounting options to fit varied installations: Front/Rear flange mounting QM/90050/22, Foot mounting QM/90050/21, Piston rod clevis QM/57025/25, and Stud/Adaptor mounting M/P71470/1 for attaching mounting hardware to the female piston rod thread. This flexibility helps optimize alignment, stroke, and speed while preserving compact form factor in automation lines.
The cylinder operates from 1 to 10 bar (14 to 145 psi) and tolerates temperatures from -5 to 80 °C (23 to 176 °F). This enables use across standard plant air systems and moderate-temperature environments while maintaining performance characteristics such as force output and sealing integrity.
Yes. The 50 mm bore, 20 mm stroke, and compact 63x63x68.5 mm footprint support precise, repeatable motion in tight work envelopes. The magnetic piston simplifies sensing for closed-loop control, while the absence of cushioning provides consistent end-of-stroke behavior. For finetuned cycles, consider compatible switches and mounting options to achieve reliable repeatability on small components.
Maintenance is streamlined with the QM/92050/00 service kit, designed for RM/92000-series 50 mm actuators. The product line also lists compatible fittings and tubing (Push-in Pneufit C variants and 6 mm tubing) and switch kits (M/50 LSU reed switch and related brackets) to support routine service, diagnostics, and quick part swaps during scheduled maintenance.
