The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X50S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 50mm stroke, 1/4" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.
A compact 50 mm throw makes the MARF50X50S a good clamp and eject fit: 981 N of push at 0.5 MPa and 881 N on retract, backed by 1374 N and 1233 N at 0.7 MPa from a bore that tops out at 200.1 kgf theoretically. The F version carries a front-cover flange as part of the cylinder itself, so the machine plate bolts straight on.
Air cushions at both stroke ends are adjustable, so a 50 mm jab at up to 800 mm/s does not hammer the covers. The stainless barrel with hard-chrome plated rod tolerates washdown and humid lines, and since every MA-series cylinder ships with its magnet fitted, a CMSG or EMSG switch drops straight on. At 60 percent of rated push you still have about 589 N for real work at 0.5 MPa.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.
| MAR | Standard round-body mini cylinder (double-acting, integrated mount, variable cushion). |
|---|---|
| F | Front-cover mount: F = front-flange mounting. |
| 50 | Bore size in mm. |
| ×50 | Stroke length in mm. |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
Clamps sheet metal before a punch stroke; 981 N at 0.5 MPa holds 2 mm plate flat and the short 50 mm stroke keeps cycle time low.
Cycles a specimen press on a test bench; the stainless barrel and hard-chrome rod survive humid lab air and frequent wipe-downs.
Kicks small bins between two conveyor lanes at the sorter, and the EMSG switch flags when the kicker is home.
With only 50 mm to travel, this size suits quick clamps rather than long feeds. If 981 N and 881 N at 0.5 MPa is oversized, the 40 mm MAR still gives 628 N push and 528 N pull; need 1558 N? The 63 mm MAR delivers it. Stay within 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s.
Mounting comes from the F front flange built into the front cover, and MAR does not accept FA, LB or SDB feet, while I and Y rod knuckles fit the 16 mm rod. The piston magnet is factory-fitted, so EMSG feedback is a clip-on rather than an option. There is no locking function: on air loss the piston drifts, so use a rod lock where a clamp must stay shut.
Quick checklist
This model pushes 981 N and pulls 881 N at 0.5 MPa, rising to 1374 N and 1233 N at 0.7 MPa; the 50 mm bore's theoretical ceiling is 200.1 kgf at 1.0 MPa. Speed range is 30-800 mm/s with a variable cushion at each end.
The F front flange is machined as part of the front cover, so MARF50X50S bolts flat to a machine plate without any separate bracket. MAR takes no FA, LB or SDB accessories, though I and Y knuckle joints still thread onto the M14x1.5 rod. A rod lock is the correct add-on if the load must hold through air loss.
