Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X160-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X160-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 160mm 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 MACJ25X160-75S
A trim window of 75 mm makes the MACJ25X160-75S the most flexible member of AirTAC's MA adjustable family: the extend stroke can be set anywhere from 85 mm to the full 160 mm by turning the external stop screw. Output sits in the 25 mm class at 245.3 N push and 206.1 N pull at 0.5 MPa (35.6 psi), rising to 343.4 N push at 0.7 MPa. Double-acting by design, it also carries a variable air cushion at both ends so end-of-stroke shock can be tuned out at higher speeds.
The body is a riveted round barrel in stainless steel wrapped around a hard-chrome plated carbon-steel rod, a build that shrugs off washdown and damp plant air far better than painted minis. At 0.5 MPa plan for roughly 147 N of usable work rather than the full rating, which translates to lifting about 12 kg vertically with a 2:1 margin. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clamp straight onto the barrel.

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 MACJ25X160-75S Is Used
Carton erecting line stop
End-of-arm stop on a carton erecting line: set the stop 85-160 mm from home so different box heights share one station, with the cushion absorbing the gate slam at 0.7 MPa.
Plastics nest ejector
Selective eject on a plastics assembly cell: the 245.3 N push at 0.5 MPa clears a rejected housing off the nest inside the cycle dwell.
Parcel divert gate
Divert gate on a roller conveyor for 12 kg parcels: run the gate at mid-band speed knowing the end cushions protect the covers from repeated stops.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X160-75S the Right Cylinder?
If 245.3 N at 0.5 MPa is more than the job needs, the 20 mm bore delivers 157.0 N in the same MACJ format; when the load outgrows this cylinder, step up to 32 mm for 402.2 N. Remember the stop screw is a position setter, not a brake - on air loss the piston drifts, so fit a valve or external stop where holding matters. FA flange or LB foot mounting plus I / Y rod knuckles cover the usual fixture needs, and the standard magnet keeps switch sensing simple. At 160 mm stroke, keep side loads off the rod or guide them externally; bending stress grows quickly at this aspect ratio.
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 MACJ25X160-75S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push rises to 343.4 N. The 25 mm bore tops out at a theoretical 50 kgf at 1.0 MPa. Working range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and stroke speed can run 30-800 mm/s.
No - every MA cylinder ships with a built-in magnet, so CMSG, DMSG and EMSG switches mount on the barrel without a special-order piston.
