About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X200-100S
Longer travels usually mean a bulkier cylinder, but the MAJ20X200-100S keeps a slim round stainless barrel over a 200 mm stroke. It is double-acting, and the external stop screw shortens the extend stroke anywhere inside the ordered 100 mm window. Push force at 0.5 MPa is 157 N; budget around 94 N for actual work on the machine.
Because the riveted body carries no tie rods, it slots into narrow frames where wider designs will not fit. The 8 mm rod suits modest side loads, though at 200 mm of travel you should still guide the load externally to protect the hard-chrome surface. The standard-built magnet means CMSG / DMSG / EMSG switches mount anywhere along the barrel for end-of-travel checks.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X200-100S Is Used
Carton reject pusher
Kicking mislabeled cartons off a packaging conveyor across a 100-200 mm lane, trimmed on the line to the exact lane width.
Tray drawer ejector
Pushing bakery trays out of a rack slot for robotic pickup, with the extend stroke trimmed to the tray depth.
Sliding guard gate
Actuating a machine-guard slide on a filling line, opening 200 mm with the stop set short of full frame travel.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X200-100S the Right Cylinder?
If 157 N at 0.5 MPa is more than the job needs, the MAJ16 gives 100.5 N in a smaller bore; if the load grows, step to MAJ25 for 245.3 N. On this long stroke keep external guides close to the load, and note the stop screw sets position but holds nothing: with air lost the piston drifts, so fit a mechanical clamp where a load must stay put. FA flange or LB foot mounting, I or Y knuckles, 1/8" ports.
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 Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X200-100S FAQ
Running at 0.5 MPa you get 157 N on the push stroke and 131.9 N on the pull stroke. Raise supply to 0.7 MPa and it becomes 219.8 N push / 184.7 N pull, with a theoretical ceiling of 32 kgf at 1.0 MPa. Ports are 1/8", the 8 mm rod carries an M8x1.25 male thread, speed is 30-800 mm/s and pressure 0.15-1.0 MPa (22-145 psi).
No. Every MA-series cylinder, including the MAJ20X200-100S, ships with the piston magnet built in as standard. CMSG, DMSG and EMSG switches clip onto the stainless barrel at any position for end-of-stroke or mid-zone detection.
