About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X250-30S
A 30 mm tuning window makes the MAJ16X250-30S easy to live with on long builds: set the extend stop anywhere between 220 and 250 mm while the cylinder stays bolted in place. Double-acting throughout, it gives 100.5 N at 0.5 MPa and 140.7 N if you raise supply to 0.7 MPa.
Inside is a two-way piston seal that stores its own grease, cutting dry-run wear on duty cycles that never stop. The 20.5 kgf theoretical peak at 1.0 MPa tells you the ceiling; for day-to-day sizing, treat this bore as a 60 N workhorse at 0.5 MPa. The riveted round stainless barrel also shrugs off splash and condensation that would chew up painted mini cylinders.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAJ16X250-30S Is Used
Gate latch actuator
Drives a latch on an outdoor machine guard; the riveted round stainless body tolerates rain and dust that flake painted mini cylinders.
Tray stop blade
Drops into a bakery tray conveyor as a stop; with the window set 220-250 mm, one cylinder serves three tray sizes without re-piping.
Mini press assist
Adds 140.7 N at 0.7 MPa to a hand lever for staking small terminals; the grease-storing seal keeps wear low across nonstop cycles.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X250-30S the Right Cylinder?
Compare before you commit: at 0.5 MPa the 16 mm bore makes 100.5 N, one step up to 20 mm lifts that to 157.0 N, and 25 mm to 245.3 N. FA and LB mounts plus I/Y rod knuckles cover most fixings. On a 250 mm stroke the 6 mm rod is long and slim, so keep side loads off it or add an external guide. Remember the adjuster sets an end position only - it is not a brake, so the rod can creep if supply drops.
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 MAJ16X250-30S FAQ
Expect 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, and 20.5 kgf theoretical max at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi) and the temperature range spans -20 to +70 C.
No. The MAJ carries fixed anti-impact bumper pads that decelerate the load at stroke end; they are not adjustable air cushions. If you need tunable cushioning, the MACJ family adds that on top of the adjustable stroke.
