About the Airtac RMH Magnetic Coupling Rodless Cylinder RMH16X450S
A 450 mm travel puts the RMH16X450S just 50 mm short of the longest stroke the 16 mm RMH bore offers. The slide is moved by a magnetic coupling with no mechanical link, so the drive tube remains sealed, and the piston chamber is isolated from the slide to keep dirt out over long continuous cycles. Its S code suffix confirms the position-sensing magnet is built in.
Loading, not pressure, is the limit at this stroke: the coupling holds 140 N and the load table allows 3 kg or 5 kg at 300 mm, with the permitted load dropping as the stroke lengthens toward 450 mm, so verify both before ordering. The cylinder takes air filtered to 40 um at 0.2-0.7 MPa, reaches 50-400 mm/s, tolerates -20 to +70 C, and its fixed end cushions can be swapped for separately ordered hydraulic shock absorbers.

How to choose
This is the second-longest 16 mm build: only RMH16X500S travels further, while RMH16X400S covers the same 140 N coupling force 50 mm shorter. Keep RMH16X450S when the application needs the extra reach but not the maximum; if the stroke is fixed at 450 mm and the load sits near the table limit, compare the RMH20 bore, which trades the M5x0.8 thread for PT1/8 and raises the holding force.
Applications
Drawer and tray handling
Extends and retracts tray stops or drawer pushers in storage stations where 450 mm of guided travel is needed to reach the far position.
Indexing fixture drive
Drives a clamping or indexing fixture through a 450 mm slide, with the guide rail holding anti-rotation accuracy across the long span.
Roller position adjustment
Adjusts idler or guide roller position on a converting line, where the long 450 mm travel gives wide lateral correction range.
FAQ
What are the key figures of the RMH16X450S?
16 mm bore, 450 mm stroke (tolerance +1.5 / 0 mm since it exceeds 250 mm), magnetic holding force 140 N, double acting with built-in guide rail and magnet, M5x0.8 ports, 0.2-0.7 MPa operating and 1.2 MPa (175 psi) proof pressure, 50-400 mm/s speed, -20 to +70 C.
What does the load table mean at a 450 mm stroke?
The catalog rates 3 kg or 5 kg up to a 300 mm stroke for the 16 mm bore and states that the allowed load falls on longer strokes, so recheck the derated figures at 450 mm. In all cases keep the load force below the 140 N magnetic holding force.
