About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X250-20S
Order the MAJ16X250-20S when a 250 mm reach needs a repeatable stop inside a 20 mm window: the external adjuster shortens the extend stroke anywhere in the 230-250 mm band without shims or new parts. At 0.5 MPa this 16 mm bore delivers 100.5 N forward and 86.4 N back, double-acting on both strokes.
Every MA-series barrel is rolled shut around aluminium covers with a stainless block, keeping the body slim enough for tight machine frames. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight on - no special piston to order. Vertical lift math: 100.5 N at 0.5 MPa is about 10 kgf, so figure on lifting roughly 5 kg with a 2:1 margin.

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 MAJ16X250-20S Is Used
Blister carton close
Swings a light folding lid on a cosmetics line; 86.4 N of return force at 0.5 MPa retracts the arm under power after each 230-250 mm push.
Sprue kicker
Taps small injection-moulded parts off the ejector side; about 60 N of practical working force is plenty for a 15 g polycarbonate moulding.
Test fixture lift
Lifts a 4 kg optical jig vertically with a 2:1 margin at 0.5 MPa; the FA flange option keeps the 6 mm rod square to the guide bushing.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X250-20S the Right Cylinder?
Size this bore against its neighbours: 20 mm buys 157.0 N at 0.5 MPa, 25 mm reaches 245.3 N, while 16 mm stays the lightest option at 100.5 N. Choose FA flange or LB foot mounting; the built-in magnet means position switches need no special order. The stop screw only shortens the extend stroke - it never lengthens past 250 mm, and it will not hold a load if air is lost.
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 MAJ16X250-20S FAQ
Push at 0.5 MPa is 100.5 N and pull 86.4 N; step up to 0.7 MPa for 140.7 N push and 120.9 N pull. The theoretical maximum is 20.5 kgf at 1.0 MPa. Air supply: 0.15-1.0 MPa (22-145 psi), fluid filtered to 40 um, speed 30-800 mm/s.
No. Every MA-series cylinder carries a built-in magnet as standard, so CMSG, DMSG and EMSG switches mount directly on the 16 mm barrel for end-of-stroke signalling.
