About the Airtac RMH Magnetic Coupling Rodless Cylinder RMH16X250S
AirTAC built the RMH16X250S on a Dia 16 mm bore with a 250 mm stroke and M5x0.8 ports. The piston drives the outer slide through magnets with no mechanical link, so the tube stays fully sealed and no piston rod takes up space; the built-in guide rail adds running accuracy, anti-rotation accuracy and load capacity. Catalog holding force at this bore is 140 N.
The 250 mm stroke sits inside the load case that allows 3 or 5 kg up to 300 mm, so you keep the full rated load across the whole travel. Stroke tolerance here is the tighter +1.0/0 mm band that applies at or below 250 mm. Fixed cushions with adjusting screws come at both ends and can be replaced by separately ordered hydraulic shock absorbers, while CMSH, DMSH and EMSH position sensors slide into the built-in groove.

How to choose
Pick RMH16X250S when you need more holding force than the Dia 10 RMH10X250S (55 N) but less bulk than the Dia 20 RMH20X250S with its PT1/8 ports. Within Dia 16, drop to a shorter stroke such as RMH16X200S if travel allows, or step up to RMH16X300S, which is the last stroke keeping the full 3/5 kg rating. The S in the code means the built-in magnet for sensor detection.
Applications
Short pick-and-place shuttle
Transferring small parts up to 5 kg over a 250 mm throw, with the guide rail holding anti-rotation accuracy at the gripper.
Stroke-end position signalling
The built-in magnet works with CMSH, DMSH or EMSH switches slid into the groove for end-of-travel detection on automated stations.
Compact guided push
Pushing or light clamping where a rod cylinder would be too long; 140 N holding force covers light duty at 0.2-0.7 MPa.
FAQ
What are the key figures of the RMH16X250S?
Dia 16 mm bore, 250 mm stroke, 140 N magnetic holding force, M5x0.8 ports, double acting with built-in guide rail, operating pressure 0.2-0.7 MPa (proof 1.2 MPa / 175 psi), speed 50-400 mm/s, temperature -20 to +70 C, stroke tolerance +1.0/0 mm, catalog load 3/5 kg up to 300 mm.
Which sensors and cushions fit this code?
The S option is the built-in magnet, so CMSH, DMSH and EMSH switches can be slid into the sensor groove. Both ends have fixed cushions with adjusting screws; hydraulic shock absorbers are available as separately ordered accessories. Run the cylinder on air filtered to a 40 um element.
