Airtac MARU Stainless Steel Mini Cylinder MARU50X200S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU50X200S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø50mm bore and 200mm 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 MARU50X200S
Two hundred millimetres of reach plus a 50 mm bore means 981.3 N of push at 0.5 MPa from a compact round-body actuator. It is double acting with a variable cushion at both ends, and the top-mount bracket is part of the front cover itself, so the cylinder bolts straight onto the frame.
Because the magnet ships inside every MAR, CMSG, DMSG or EMSG switches drop on for end-of-stroke detection without a special order. The stainless barrel shrugs off condensation and mild washdown where painted minis rust through. Theoretical vertical lift at 0.5 MPa is about 100 kg; halve that for a 2:1 margin and you can reliably raise a 50 kg part or pallet fixture.

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 MARU50X200S Is Used
Locating pin on an EV battery tray jig
Seats and releases a deep locating pin across weld fixtures; 981.3 N at 0.5 MPa overcomes chip-packed bushings without a fight.
Roller-bed gate latch on a sortation mezzanine
Drops a spring-loaded gate across the roller bed; the top-mount bracket fixes to the mezzanine rail with four bolts and no extra hardware.
Lid clamp on a pilot-scale mixing vessel
Pulls the hinged lid down before agitation starts; the stainless barrel tolerates the humid, splashed environment around open vessels.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU50X200S the Right Cylinder?
Compare 0.5 MPa push figures before you commit: 628.3 N from a 40 mm bore, 981.3 N here, and 1557.9 N from the 63 mm step-up. This model breathes through 1/4 in. ports with an M14x1.5 male rod thread and runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s. The integrated U bracket means no separate flange or foot to buy; I and Y rod knuckles still fit the 16 mm rod. Air loss lets the piston drift, so spec a rod lock if the load must stay put. At 200 mm stroke, guide the load or keep thrust in line with the rod axis - long strokes amplify any side force.
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 MARU50X200S FAQ
At 0.5 MPa: 981.3 N on extend, 880.8 N on retract. At 0.7 MPa: 1373.8 N extend and 1233.1 N retract. Theoretical maximum force is 200.1 kgf at 1.0 MPa. Sizing with roughly 589 N at 0.5 MPa leaves a sensible margin.
Yes. Variable air cushions sit at both ends; adjust the needle screws on commissioning to bleed the last of the stroke gently. Within the 30-800 mm/s speed range you can then run faster cycles or heavier loads without hammering the aluminium covers.
