Airtac MARU Stainless Steel Mini Cylinder MARU50X210S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU50X210S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø50mm bore and 210mm 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 MARU50X210S
Need a little past the common 200 mm mark? The MARU50X210S stretches a 50 mm bore over 210 mm of stroke while still pushing 981.3 N at 0.5 MPa, with a variable cushion at each end and a top-mount bracket rolled into the front cover.
The riveted stainless body and hard-chrome rod laugh at condensation in outdoor gates and humid plants, and the built-in magnet means CMSG, DMSG or EMSG switches mount the day the cylinder arrives. Vertical lift at 0.5 MPa works out near 100 kg theoretical; keep a 2:1 factor and plan on hoisting about 50 kg reliably per cylinder.

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 MARU50X210S Is Used
Tray lowerator in a bakery dispatch bay
Lowers stacked bread trays one level at a time; the bore supports roughly 50 kg vertical lifts with a 2:1 margin at 0.5 MPa.
Mold ejection on a bench-top injection press
Drives long ejector travel on prototype molds; 981.3 N at 0.5 MPa frees parts from shallow cavities without a hydraulic unit.
Infeed gate on a can depalletizer
Sweeps one layer of cans onto the discharge conveyor per cycle; the stainless barrel handles the wet, condensation-heavy surroundings of can lines.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU50X210S the Right Cylinder?
Forces scale with bore, not stroke: the 40 mm MAR pushes 628.3 N at 0.5 MPa, this bore 981.3 N, the 63 mm bore 1557.9 N. Threads and ports stay simple - M14x1.5 rod, 1/4 in. air ports, 0.15-1.0 MPa (22-145 psi) supply, 30-800 mm/s speed. The integrated U mount replaces a separate flange or foot, and no external bracket accessories are needed for this series. Expect the rod to drift on air loss; the cushion only softens the ends, so a rod lock is the fix where holding matters. With 210 mm of unsupported rod, side loads are the main enemy - guide long loads in linear bearings and keep thrust on the rod axis.
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 MARU50X210S FAQ
At 0.5 MPa: 981.3 N push, 880.8 N pull. At 0.7 MPa: 1373.8 N push, 1233.1 N pull. Theoretical maximum is 200.1 kgf at 1.0 MPa. Design around roughly 589 N of working push at 0.5 MPa and the actuator will not run near its limit.
No. Like any plain double-acting cylinder, the piston drifts when pressure drops - the variable cushions only soften the stroke ends, they are not brakes. For loads that must stay put, add a rod lock on the 16 mm rod or use external mechanical stops.
