Airtac MARU Stainless Steel Mini Cylinder MARU50X250S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU50X250S is a genuine double acting + cushion (up 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 MARU Stainless Steel Mini Cylinder MARU50X250S
Long travel in a compact round body: the MARU50X250S runs AirTAC MAR performance over 250 mm, pushing 981.3 N and pulling 880.8 N at 0.5 MPa, and 1373.8 N / 1233.1 N at 0.7 MPa. The up-mount bracket is formed into the front cover, cutting a separate flange from your parts list.
Divide the push by gravity and this bore balances about 100 kg - halve it and you can still lift roughly 50 kg vertically at 0.5 MPa with a 2:1 margin. The rolling-packed stainless barrel with a hard-chrome 16 mm rod shrugs off washdown and light corrosion, and the variable cushion at each end absorbs stroke-end shock at speeds up to 800 mm/s. CMSG / DMSG / EMSG switches clip on thanks to the magnet fitted as standard.

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 MARU Stainless Steel Mini Cylinder MARU50X250S Is Used
Pallet stopper
Raises or drops a stop blade across a roller lane in a warehouse, the long stroke clearing the full pallet width.
Scrap chute gate
Opens a heavy slide gate on a machining line, where 981 N of push comfortably beats gate friction and chip build-up.
Fixture ejector
Knocks finished housings out of a drill jig, the 250 mm stroke pushing the part clear of the operator's reach.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU50X250S the Right Cylinder?
Compare both directions before you commit: the 40 mm MAR gives 628.3 N push at 0.5 MPa for lighter work, while the 63 mm bore jumps to 1557.9 N when the load demands it. Over 250 mm of stroke, keep side loads off the 16 mm hard-chrome rod or guide the load externally - rod bending, not raw force, is what ends long-stroke minis early. Air supply of 0.15-1.0 MPa (22-145 psi) covers the whole range. If the load must stay put on air failure, pair the cylinder with a rod lock; the cushion alone only softens the stroke end.
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 MARU Stainless Steel Mini Cylinder MARU50X250S FAQ
0.5 MPa gives 981.3 N push and 880.8 N pull; 0.7 MPa gives 1373.8 N push and 1233.1 N pull; the 1.0 MPa theoretical peak is 200.1 kgf. Air range is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
No - every MAR ships with the piston magnet already fitted, so CMSG, DMSG or EMSG switches click onto the barrel for end-of-stroke or mid-stroke signals at no extra option cost.
