Norgren RA/193050/M/25 Pneumatic Cylinder - ISO 21287
Part Number: RA/193050/M/25
Quick Summary
Norgren RA/193050/M/25 is an ISO compact single-acting pneumatic cylinder that delivers precise linear actuation for space-constrained automation. In many manufacturing setups, limited mounting room and varied installation environments create reliability challenges; this model mitigates those issues with a 50 mm bore and a 25 mm stroke designed for compact layouts. It conforms to ISO 21287, features a magnetic piston for easy sensing, and uses low-friction, long-life seals to minimize maintenance. The cylinder also supports flush-mount switches and a broad range of Pneufit C fittings and mounting options, delivering faster installation and predictable lifecycle performance. This combination translates into reduced downtime, lower total cost of ownership, and smoother integration into RA/193000/M family systems for consistent plant-wide actuation.

FAQs
Begin by preparing a clean, unobstructed mounting surface and verify the G1/8 port alignment. Use compatible Pneufit C fittings for inlet and return lines, ensuring correct sealant or thread tape where required. Torque recommendations follow standard ISO practice for metric cylinder threads, and keep the magnetic piston unobstructed to preserve sensing accuracy. After mounting, test actuations at low cycle rates before full production runs.
The cylinder operates from 2 to 10 bar (29 to 145 psi) and is rated for an ambient temperature range of -5 to 80 °C (23 to 176 °F). This makes it suitable for most factory automation environments, including intermittent heat zones, while preserving seal life and stroke performance within its ISO standard specification.
Yes. With a 50 mm bore and 25 mm stroke, this ISO Compact cylinder provides a compact yet capable actuation option for tight spaces. The theoretical force of about 906 N supports moderate clamping or transfer tasks, and the magnetic piston allows straightforward integration with position sensing for reliable pick-and-place cycles in space-constrained lines.
The RA/193050/M/25 conforms to the ISO 21287 standard for compact pneumatic cylinders. It includes a magnetic piston for sensing compatibility and durable construction with anodised aluminium barrel and stainless steel piston rod. No additional regulatory certifications are listed beyond ISO 21287 in the provided data, so verify local CE or industry-specific requirements as needed for your application.
A wide range of mounting accessories is available, including swivel hinge mounts, rear clevis, eye mounts, and piston rod swivels, tailored for 50 mm bore cylinders. Service kits (QA/192050/55) cover RA/192000 family maintenance, and there are compatible fittings (Pneufit C), tubing, and 5V reed-switch options for integrated sensing. These options simplify installation, retrofit, and ongoing maintenance for reliable operation.
