About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-50S
With a 25 mm bore pushing 245.3 N at 0.5 MPa (about 25 kg of force), the MAJ25X160-50S is a double-acting round-body mini cylinder whose extend stroke can be trimmed anywhere inside a 50 mm window by an external stop screw. Air drives the rod in both directions across 160 mm of travel at 30-800 mm/s, and fixed bumper pads soften the stroke ends.
The riveted stainless barrel and hard-chrome plated rod shrug off mild corrosion, so this mini survives damp workshops and washdown corners where painted-steel cylinders fail. A magnet comes built in as standard, so CMSG, DMSG or EMSG switches mount straight onto the barrel. At 0.6 of the 245.3 N rating, plan on roughly 147 N of real working force at 0.5 MPa.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MAJ25X160-50S Is Used
Part ejection on assembly stations
Eject stamped clips or housings from a nest after press forming; the 50 mm trim window lets technicians dial in the exact extend position for a 160 mm reach.
Push-off gates on packaging lines
Knock off-spec cartons off a conveyor; 245.3 N at 0.5 MPa moves light carton loads quickly and the stainless barrel copes with damp washdown zones.
Lift-and-present fixtures
Raise jigs or small parts vertically; the 25 mm bore lifts about 12.5 kg vertically at 0.5 MPa with a 2:1 margin on the theoretical 25 kg.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-50S the Right Cylinder?
Size it from both sides: the 20 mm bore delivers 157.0 N push at 0.5 MPa, while stepping up to 32 mm buys 402.2 N. Between those, the 25 mm bore covers mid-range ejection and clamping. The stop screw only limits the extend stroke, so with air lost the piston can still drift - never treat the adjuster as a load-holding brake. FA flange and LB foot mounts, plus I and Y rod knuckles, fit most frames (no SDB on adjustable models). For a 160 mm stroke, guide the load to limit side load on the 10 mm rod with its M10x1.25 male thread.
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 MAJ25X160-50S FAQ
At 0.5 MPa the 25 mm bore pushes with 245.3 N and pulls with 206.1 N; at 0.7 MPa push reaches 343.4 N, and the theoretical maximum at 1.0 MPa is 50 kgf. The cylinder runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
Bore 25 cylinders take 1/8" ports (PT as standard, G or NPT on request) and carry a 10 mm hard-chrome rod with an M10x1.25 male thread. The external stop screw trims the extend stroke anywhere within the ordered 50 mm window.
