Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X60-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X60-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 60mm 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 MACJ25X60-50S
Half of this cylinder's travel is adjustable: with the 50 mm window, extend stroke can be set anywhere from the full 60 mm down to 10 mm, so one station handles short and long parts without swapping actuators. It is double-acting with a variable air cushion at both ends, pushing 245.3 N at 0.5 MPa.
Under the skin sits AirTAC's MA construction: a stainless barrel riveted to aluminium-alloy covers with a stainless block, plus a carbon-steel rod hard-chrome plated to 20 um for corrosion resistance. In practice plan on close to 147 N of continuous push at 0.5 MPa - about 12 kg of vertical lift with a 2:1 safety margin - and borrow the full 245.3 N only for short peaks.

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 MACJ25X60-50S Is Used
Drill fixture depth stop
Limiting penetration on a pneumatic drilling jig by trimming extend travel instead of shimming hard stops against the jig.
Checkweigher reject pusher
Pushing underweight packs off a checkweigher belt, with the air cushion letting the reject flap land quietly at line speed.
Woodworking clamp slide
Clamping cabinet door stock in a doweling machine, where the stainless barrel tolerates dusty, humid workshop air.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X60-50S the Right Cylinder?
Work down the force ladder at 0.5 MPa: bore 20 gives 157.0 N, this bore 25 gives 245.3 N and bore 32 gives 402.2 N - size by working load, not stall force. The 50 mm adjuster trims the extend stroke as a hard stop and will not hold a load when air is lost, so add a locking or 3-position valve for anything suspended. Choose FA flange or LB foot mounting and an I or Y knuckle for swivel joints, then drop a CMSG / DMSG / EMSG switch onto the standard magnet for end-of-travel signals. Port is 1/8".
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 MACJ25X60-50S FAQ
Within the ordered 50 mm window the extend stroke can be set from the full 60 mm down to 10 mm; retract travel stays at full length. The stop screw is a position end stop, not a mid-stroke brake - with air lost the piston drifts - so never rely on it alone to hold a load.
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; 50.0 kgf theoretical maximum at 1.0 MPa. Operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
