About the Airtac RMH Magnetic Coupling Rodless Cylinder RMH10X50S
With just 50 mm of stroke, RMH10X50S is the shortest and most compact build in the Dia 10 rodless range, made for tight envelopes where a rod cylinder's extra installed length would not fit. The slide is moved by magnetic coupling with no piston rod, so the sealed tube and isolated piston chamber resist dirt, and the built-in guide rail carries the load with controlled anti-rotation.
Specs match the rest of the Dia 10 family: 55 N magnetic holding force, M5x0.8 ports on one side, fixed cushions with adjusting screws at both ends, and a +1.0 / 0 mm stroke tolerance. It runs on 40 um-filtered air at 0.2-0.7 MPa, 50-400 mm/s, -20 to +70 C, with CMSH, DMSH or EMSH switches fitting the sensor groove.

How to choose
Choose RMH10X50S when travel is short and the mounting envelope matters most; RMH10X250S and RMH10X300S share the same 55 N coupling and M5x0.8 ports for longer moves. At this stroke you get the full benefit of the catalog loading case - 1.4 / 2.4 kg is quoted for Dia 10 up to 200 mm of stroke - so the maximum allowed load applies. If 55 N of holding force is marginal for your thrust, the RMH16 bore raises it to 140 N.
Applications
Clamping and part presenting
Short 50 mm advance clamps or presents a small part at a fixture, with the guide rail keeping the slide square under the clamp reaction force.
Edge ejection of small parts
Fires small components off a conveyor edge in a 50 mm push, sized to fit where there is no room alongside the belt for a rod cylinder body.
Fine adjustment slide in tooling
Acts as a manually or pneumatically trimmed positioning slide for tooling set-up, with CMSH, DMSH or EMSH switches confirming the adjusted position.
FAQ
What are the key specifications of the RMH10X50S?
Dia 10 mm bore, 50 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, 0.2-0.7 MPa operating pressure, -20 to +70 C, 50-400 mm/s, stroke tolerance +1.0 / 0 mm.
What load can this short-stroke version handle?
Because 50 mm sits well inside the catalog's Dia 10 loading case of 1.4 / 2.4 kg up to 200 mm of stroke, the maximum quoted load applies without the reduction seen on longer variants. The separate magnetic limit also applies: keep the acting load force below the 55 N holding force of the coupling.
