Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X125-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X125-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 125mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X125-10S
An adjustable extend stroke and twin variable air cushions define the MACJ25X125-10S: the stop screw narrows the 125 mm stroke within a 10 mm window, trimming exact positions without re-plumbing. The rolled round body pairs a stainless barrel with a 20 um hard-chrome rod, an edge over painted minis in damp or food-area duty. Ports are 1/8 in., the 10 mm rod carries an M10x1.25 male thread, and the running range spans 30-800 mm/s at 0.15-1.0 MPa (22-145 psi).
At 0.5 MPa (73 psi) this 25 mm bore pushes 245.3 N and pulls 206.1 N; 0.7 MPa (102 psi) lifts push to 343.4 N, topping out at 50 kgf theoretical at 1.0 MPa (145 psi). Budget about 147 N of practical work at 0.5 MPa (73 psi) - enough to raise roughly 12 kg vertically on a 2:1 margin. The piston magnet is factory-fitted, so CMSG, DMSG or EMSG switches mount with no special order.

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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X125-10S Is Used
Fixture clamp
Clamps aluminium housings in a CNC milling fixture; the 10 mm window dials clamp position to match casting tolerances run to run.
Carton flap tuck
Folds a flap on a slow packing line; about 147 N of working force closes board flaps cleanly without crushing the carton.
Index stop
Drops into a rotary indexing table as a stop pin, with the variable cushion absorbing index shock at every cycle.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X125-10S the Right Cylinder?
For jobs lighter than 245.3 N at 0.5 MPa (73 psi), the 20 mm bore (157.0 N) saves air; heavier cycles point to the 32 mm bore at 402.2 N. Remember the adjuster fixes the extend endpoint only - it is not a mid-stroke brake, and a lost-air load will settle. Choose FA flange or LB foot mounting, add I or Y rod knuckles where the load pivots, and rely on the standard magnet for CMSG or EMSG switch drop-on.
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 On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X125-10S FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa (73 psi); push 343.4 N and pull 288.5 N at 0.7 MPa (102 psi); theoretical maximum 50 kgf at 1.0 MPa (145 psi).
No. Every unit leaves the factory with a piston magnet already built in - CMSG, DMSG and EMSG switches fit the barrel without a special-order piston. Thread is PT as standard, with G and NPT available to order.
