Airtac MARF Stainless Steel Mini Air Cylinder MARF50X250S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X250S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 250mm 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.

About the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X250S
MARF50X250S pairs a 250 mm stroke with the MAR's riveted round body: a stainless-steel barrel rolled onto aluminium covers, no tie-rods, with a hard-chrome plated 16 mm rod. It is double acting with a variable air cushion at both ends, and the front flange (F) bracket is already part of the front cover, so the 50 mm bore bolts straight onto the machine face. At 0.5 MPa it pushes 981 N and pulls 881 N.
At 0.7 MPa the same bore reaches 1374 N on extend, and the theoretical ceiling is 200 kgf at 1.0 MPa. For real work budget roughly 589 N, about six tenths of the rated push, which comfortably covers clamping and part-transfer duties in that band. The magnet is built in as standard, so a CMSG, DMSG or EMSG switch clips on whenever end-of-stroke signals are needed.

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.
Theoretical Output Force (Ø50mm)
| 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.

Where the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X250S Is Used
Pallet-gate lifting
At 0.5 MPa the bore can raise roughly 50 kg with a 2:1 margin, enough for a 40 kg aluminium guard gate over a 250 mm lift.
Weld-fixture clamping
A 589 N working budget seats clamps on automotive brackets, while the cushion stops the clamp arm slamming home.
Carton push-off
Side-ejects 15 kg cartons from a takeaway conveyor; the 250 mm stroke clears the full belt width.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X250S the Right Cylinder?
Down one size, a 40 mm MAR flange cylinder delivers 628 N at 0.5 MPa; up one size, the 63 mm bore gives 1558 N, so 50 mm sits squarely in the mid-force band. A 250 mm stroke running anywhere in the 30-800 mm/s window is fine, but keep side load off the 16 mm rod and guide the payload externally when the move is not purely axial. Like any plain double-acting cylinder, this one drifts if air pressure drops, so add a rod lock if the position must survive a supply failure. The integrated front flange replaces a separate foot or bracket, and the standard magnet matches CMSG, DMSG and EMSG switches.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MARF Stainless Steel Mini Air Cylinder MARF50X250S FAQ
At 0.5 MPa it pushes 981.3 N and pulls 880.8 N; at 0.7 MPa push rises to 1373.8 N. The theoretical maximum for this 50 mm bore is 200.1 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), speed runs 30-800 mm/s, and the 250 mm stroke sits inside the 500 mm standard maximum.
Both ends carry a variable air cushion. On first run, turn the needle screws at the covers until end-of-stroke shock disappears, then re-check whenever speed or load changes. With a 30-800 mm/s speed window and a 250 mm stroke, this keeps fast or heavy moves from hammering the aluminium covers.
