IMI Norgren RM/91050/M/25 Compact Cylinder - 1/3 Length
Part Number: RM/91050/M/25
Quick Summary
The RM/91050/M/25 compact single acting cylinder delivers reliable linear actuation for automation lines and pick-and-place cells. In tight spaces, traditional cylinders struggle with footprint and maintenance, escalating downtime and costs. Designed with a magnetic piston and fully non-corrodible construction, this model offers long life and consistent performance, even in demanding environments. With a 50 mm bore and a 25 mm stroke, it integrates easily with standard Pneufit C fittings and mounting options, delivering predictable cycle times. For engineers and procurement teams, the combination of compact geometry, rugged materials, and easy service translates into lower total cost of ownership and faster project delivery.

FAQs
Yes. RM/91050/M/25 supports Pneufit C push-in fittings (including C0L510618 variants) and is compatible with RM mounting families. Mounting options include M/P71470/1 stud/adaptor mounting and QM series mounts for 50 mm bores, enabling straightforward integration with existing RM/92000/M and RM/91000/M actuators.
The cylinder operates from -5 to 80 °C and is rated for 2 to 10 bar (29 to 145 psi) of compressed air, making it suitable for a broad range of industrial environments and automated processes.
Mounting options include Stud or Adaptor mounting (M/P71470/1) for attaching F mounting to the female piston rod thread, along with QM/90050 series front/rear flange mounts (50 mm bore) and QM/90050/21 foot mounting. This provides versatile installation for robotic arms, clamps, and end-effectors.
Service kits are available for RM/92000, 50 mm variants (QM/92050/00), enabling easy field maintenance and part replacement. For sensing and control integration, switch brackets (M/P72487B) and M/50 reed switches (M/50/LSU/5V) can be added to support reliable feedback and automation workflows.
Ideal for space-constrained pick-and-place, clamping, and end-effector actuation in packaging, assembly, and machine-tending tasks. Its 50 mm bore, 25 mm stroke, magnetic piston, and robust materials support reliable performance in high-cycle environments with straightforward integration into existing pneumatic systems.
