Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X25-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X25-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MACJ32X25-10S
A short-stroke MACJ in the 32 mm bore class, double-acting with an adjustable extend stroke and a variable air cushion at both ends. The trim window here is 10 mm, so the stop screw shortens the 25 mm extend stroke on site without swapping parts. At 0.5 MPa the piston delivers 402 N on the extend side, which in practice means planning around 241 N of real work for a comfortable margin.
The body is a riveted stainless-steel round barrel with a hard-chrome plated 12 mm rod, so mild corrosion and washdown mist are far less of a worry than with painted minis. A magnet is built in as standard, letting CMSG, DMSG or EMSG switches clamp straight onto the barrel for end-of-stroke signalling.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MACJ32X25-10S Is Used
Clamp fixture on a CNC fixture plate
Short 25 mm clamp moves backed by 402 N of push hold aluminium parts tight, while the 10 mm window lets the clamp pad travel be fine-tuned after each tooling change.
Small-box ejector on a carton packing line
Ejects light cartons off a belt at up to 800 mm/s, and the dual variable cushion keeps the eject stop quiet even at high cycle rates.
Part-present push-off with end detection
The built-in magnet pairs with CMSG or DMSG switches so the PLC confirms both rod positions before the next station indexes.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X25-10S the Right Cylinder?
Compare both directions before locking the bore: the 25 mm bore pushes 245 N at 0.5 MPa while this 32 mm unit gives 402 N, and the 40 mm bore reaches 628 N if loads grow. Keep in mind the adjuster is a mechanical extend stop only - with air lost the rod still drifts, so do not count on it to hold a load mid-travel.
FA flange or LB foot mounting suits fixed frames, and the standard magnet means position switches bolt on from day one. Air supply 0.15-1.0 MPa (22-145 psi), rod speed 30-800 mm/s.
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 MACJ32X25-10S FAQ
At 0.5 MPa it pushes with 402 N and pulls with 346 N. Raise the supply to 0.7 MPa and those climb to 563 N push and 484 N pull. The theoretical maximum at 1.0 MPa is 82 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) and rod speed runs 30-800 mm/s.
No. Every MACJ32X25-10S ships with the piston magnet built in as standard, so CMSG, DMSG and EMSG reed or electronic switches clip onto the stainless barrel and read the 12 mm rod position without any special-order piston.
