Helpful for Model Matching:

  • Full RMT code or label, bore and exact stroke
  • Load mass, orientation, centre offset, speed and available pressure
  • Sensor S option, CMSG/DMSG/EMSG and rail scope
  • Blank adjustable nuts or A absorbers, port/thread, installed clearance
  • Quantity and destination
  • Match adjustable-nut or shock-absorber envelope and top/bottom mounting.
  • Bore16 port is metric M5×0.8; verify actual larger-bore thread.
  • Use load-speed-stroke curves with pressure, orientation and offset.
  • Confirm S sensing magnet and sensor-rail mounting scope.

Catalogue Technical Specifications

AirTAC reference data
Actuation / guideDouble acting; magnetically coupled carriage/piston; twin guides. The S option refers to sensing magnets, not whether the drive uses magnetic coupling.
Bore / standard strokes16:50–500 in50mm steps. 20/25/32:50–500 in50mm steps plus600,700,750,800. 40:50–500 in50mm steps plus600,700,750,800,900,1000.
Maximum stroke16:750mm;20:1000mm;25/32/40:1500mm. These are maximum limits, not additional standard-stroke entries. Non-standard strokes require consultation.
Pressure / proofBore16 operating0.2–0.7MPa;20/25/32/40 operating0.25–0.7MPa. Proof1.2MPa is not operating pressure.
Air / temperature / speedAir filtered40μm or finer;−20 to70°C;50–400mm/s. Apply anti-freezing measures at low temperature; select load and speed together.
Safe holding force16/20/25/32/40:140/220/345/560/880N. Holding force is not load capacity in kg and is distinct from the theoretical force versus pressure chart.
Load / stroke boundaryCentred slide-table load row:16 up to5.6kg through300mm;20 up to9.6kg through500mm;25 up to16kg through500mm;32 up to24kg through600mm;40 up to40kg through600mm. Longer strokes and horizontal/vertical speed use the published curves; no universal maximum payload.
Cushion / shock absorberBlank:two adjustable nuts;A:two shock absorbers. Fixed rubber bumpers are described. Shock absorbers are consumable parts; never loosen their bottom screw.
Shock absorber / setting torque16 ACA1006-A1.67Nm;20 ACA1007-1N1.67Nm;25 ACA1412-1N3.14Nm;32/40 ACA2020-1N10.80Nm. Torque refers to the shock-absorber setting nut.
Port / thread16:M5×0.8, metric only;G/NPT consult.20/25/32:1/8;40:1/4. Larger bores blankPT,G=G,T=NPT. The bore16 footnote overrides the general blankPT legend.
Sensor / mounting scopeSensors only on S versions: CMSG,DMSG,EMSG. Magnet positions at body corners; sensor-switch rail uses mounting holes on both groups. Switch/rail quantities and exact suffixes require confirmation.
Stroke tolerance0–250mm:+1.0/0mm;251–1000:+1.5/0mm;1001 and above:+2.0/0mm. Tolerance bands do not establish standard availability.
Installation / materialsTop/bottom mounting shown. Prefer non-magnetically conductive workpiece material. Material table is bore-specific representative data; do not apply every material row to all bores. Midway stopping with an external limit device refers to RMS, not an added RMT option.

Avoid a wrong match

  • Maximum stroke is not the standard list:16×750,20×1000,25/32×1500 require confirmation.
  • Bore16 is M5×0.8 metric only; do not silently assign PT/G/NPT.
  • Holding force in N is not centred load in kg; pressure/load-speed/stroke curves are separate checks.
  • Without S, sensor-switch use is not supported by the catalogue. Switch and rails are not assumed included.
  • Proof pressure1.2MPa is not the0.7MPa operating limit.
  • Do not treat ordinary S/A/thread options as separate family pages.

Read the model code

If the label is incomplete, send the readable parts together with a photo.

RMT 20 × 100 S A G

20 × 100Bore and standard stroke

Bore 20 mm and stroke 100 mm; match the exact published bore row. Maximum stroke is not standard availability.

S A GSensing magnet, absorbers and thread

S sensing magnets, A two shock absorbers, G thread. Bore 16 uses metric only; larger bores blank PT, G or T for NPT.

About RMT

RMT is a twin-guide, magnetically coupled rodless-cylinder family for compact guided motion. Confirm bore and the exact standard-stroke row first, then sensing magnet, cushion and thread. Load selection must combine pressure, stroke, speed, orientation and offset; a holding-force number alone does not establish payload.

Matching Questions

Is every stroke below the maximum a standard model?

16:50–500 in50mm steps. 20/25/32:50–500 in50mm steps plus600,700,750,800. 40:50–500 in50mm steps plus600,700,750,800,900,1000. 16:750mm;20:1000mm;25/32/40:1500mm. These are maximum limits, not additional standard-stroke entries. Non-standard strokes require consultation.

Can I choose the bore from holding force alone?

No. The safe holding-force table is in N, not kg. Use pressure, centred/offset load, stroke, horizontal or vertical orientation and speed curves together. Send the installed conditions for confirmation.

Can sensors be used without the S option?

The catalogue limits sensors to cylinders with sensing magnets,S. It lists CMSG,DMSG,EMSG; confirm exact switch and rail scope separately. Magnetic drive coupling is present even when S is absent.
