About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X200-20S
A 200 mm reach paired with a short 20 mm tuning window makes the MAJ20X200-20S a natural fit for long slides that need only slight final trim. Double-acting with air on both faces, it pushes 157 N at 0.5 MPa and 219.8 N at 0.7 MPa; treat about 94 N as the realistic working force.
Construction is a riveted stainless round barrel with a hard-chrome carbon-steel rod, so splash zones and outdoor locations are handled without paint flaking off. The stop screw trims the extend stroke only - it is an end stop, not a brake, and the rod will drift if air pressure is lost. Fixed anti-impact pads cushion both ends of travel.

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 MAJ20X200-20S Is Used
Pallet-label pusher
Pushing labels onto palletized produce cartons across a long lane, trimmed to the label-head position.
Stack aligner
Squaring paper or film stacks on a print-finisher outfeed before strapping, using about 94 N of working force.
Sample tray lift
Raising laboratory sample trays at a transfer station - with margin applied the bore-20 piston lifts about 8 kg vertically.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X200-20S the Right Cylinder?
Need less force? The MAJ16 delivers 100.5 N at 0.5 MPa. Need more? MAJ25 reaches 245.3 N. For 200 mm of travel, guide the load externally so the 8 mm rod sees minimal side load, and keep in mind the adjuster holds no load on air loss. Choose FA flange or LB foot mounting with I or Y knuckles as the job demands; the built-in magnet and CMSG / DMSG / EMSG sensor compatibility are standard, with 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 MAJ20X200-20S FAQ
The full figure set: 157 N push and 131.9 N pull at 0.5 MPa; 219.8 N push and 184.7 N pull at 0.7 MPa; 32 kgf theoretical maximum at 1.0 MPa. Port is 1/8", rod is 8 mm with M8x1.25 male thread, stroke 200 mm with a 20 mm adjustable window, speed 30-800 mm/s, pressure 0.15-1.0 MPa (22-145 psi).
Yes, better than most painted minis: the barrel is stainless steel and the 8 mm rod is hard-chrome plated to about 20 um, so mild corrosion and washdown splash are handled. Just remember the fixed bumper pads soften stroke-end impact only and are not adjustable cushions.
