About the Airtac RMH Magnetic Coupling Rodless Cylinder RMH10X250S
The AirTAC RMH10X250S pairs a Dia 10 mm magnetically coupled piston with a 250 mm stroke on a built-in guide rail slide. The piston drives the slide through magnets alone, so the tube stays fully sealed with no piston rod, and the isolated piston chamber keeps dirt out of the drive. At this bore the magnetic coupling holds 55 N, and the S in the order code confirms the built-in magnet that works with position sensing.
Ports are M5x0.8 on one side, both ends carry fixed cushions with adjusting screws, and stroke tolerance is +1.0 / 0 mm at this length. Run it on air filtered to 40 um at 0.2-0.7 MPa, -20 to +70 C, 50-400 mm/s, with CMSH, DMSH or EMSH switches seated in the built-in groove.

How to choose
Within Dia 10, RMH10X50S is the compact choice for short moves and RMH10X300S reaches the bore's maximum stroke; 250 mm sits between them. The catalog's 1.4 / 2.4 kg loading case is listed up to 200 mm of stroke, and the allowed load falls on longer strokes, so confirm the reduced figure for 250 mm from the datasheet. If your holding force demand exceeds 55 N, step up to the RMH16 bore with 140 N. The M5x0.8 port is fixed at Dia 10; G and NPT thread codes apply only to Dia 20 and 25.
Applications
Cross-feed between conveyor lanes
Shifts cartons or trays sideways by 250 mm between adjacent lanes, with the guide rail taking the side load that a plain rodless slide would transfer into the tube.
Gantry pick-and-place lateral axis
Provides the horizontal shuttling axis on a compact gantry, cycling at 50-400 mm/s while the sealed magnetic coupling keeps the work area free of rod grease and dust.
Position feedback on a long slide
CMSH, DMSH or EMSH switches clip into the built-in groove anywhere along the 250 mm travel, giving end-of-stroke or mid-position signals without external brackets.
FAQ
What are the key specifications of the RMH10X250S?
Dia 10 mm bore, 250 mm stroke, double acting with magnetic coupling, 55 N holding force, built-in guide rail and magnet (code S), M5x0.8 ports on one side, fixed cushions with adjusting screws, operating pressure 0.2-0.7 MPa, temperature -20 to +70 C, speed 50-400 mm/s, stroke tolerance +1.0 / 0 mm.
How much load can the slide carry at 250 mm of stroke?
The Dia 10 catalog loading case gives 1.4 / 2.4 kg up to 200 mm of stroke, and the allowed load falls on longer strokes, so the permitted load at 250 mm is lower - confirm the exact value from the datasheet. Independently, keep the load force below the 55 N magnetic holding force.
