About the AirTAC RMS
The AirTAC RMS is a double-acting, magnetically coupled rodless cylinder: the piston in the tube and the slider outside it are linked only by magnets, with no mechanical connection, so the tube stays sealed. With no piston rod it needs far less mounting length than a rod cylinder of the same stroke, and strokes reach 3000 mm on Ø32.
Adjustable cushions at both ends (fixed bumpers on Ø10; adjustable cushions plus fixed bumpers on the RMSP) make reversals smooth without impact, and because the piston and slider are separate, dust and dirt stay out of the tube, which extends its life. It works from 0.15 to 0.7 MPa (0.2 to 0.7 MPa on Ø10), proof 1.2 MPa, -20 to +70 °C, at 50 to 400 mm/s.

Where the RMS Is Used
Long-stroke transfer
Moves a carriage over long strokes in a short machine.
Pick and place gantries
The slider carries light tooling along the tube.
Dusty areas
The sealed tube keeps dirt away from the piston.
Choosing the Right RMS Configuration
Choose the bore by the load. The catalog safety holding force is Ø16 140 N, Ø20 220 N, Ø25 345 N, Ø32 560 N; keep the load and its inertia below it so the slider stays coupled to the piston.
Then the stroke. Standard strokes run in 50 mm steps to 500 mm, then 600, 700, 750, 800, 900 and 1000 mm (Ø10 to 300 mm, Ø16 to 500 mm); the maximum is Ø16 1500 mm, Ø20 2000 mm, Ø25 2500 mm, Ø32 3000 mm. The 130, 490, 1110, 1200, 1300, 2800, 3000 mm codes on this page are non-standard strokes.
Then the model and mounting. RMS is the standard version; RMSP and RMSF are the catalog's P-size (Ø16/20/32) and F-size (Ø16 to Ø40) versions. LB adds foot brackets and FA a flange plate (no FA on RMSF40); no letter means no mounting accessory. Ø10 and Ø16 have metric ports; larger bores have PT as standard, with G or NPT on code G or T.
AirTAC RMS FAQ
Magnets in the piston and in the slider pull on each other through the tube wall, so the slider follows the piston with no mechanical link and the tube stays sealed.
Yes, with an external stopper and a shock absorber; for mid-stroke stops keep the pressure at 0.55 MPa or less.
RMSP and RMSF are the catalog's P-size and F-size versions; LB is a foot bracket set and FA a flange plate. No letter means the standard RMS without mounting accessories.
0.15 to 0.7 MPa (0.2 to 0.7 MPa on Ø10), proof 1.2 MPa, 50 to 400 mm/s, -20 to +70 °C, on air filtered to 40 µm.
