About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X225-20S
Field-settable by 20 mm, this MACJ balances flexibility and simplicity: the stop screw shortens the extend stroke anywhere within 20 mm of the 225 mm nominal travel. The 32 mm bore is double-acting, cushioned at both ends, and pushes 402 N at 0.5 MPa (563 N at 0.7 MPa) - mid-range muscle for gates, stoppers and small presses.
Its riveted stainless barrel with a hard-chrome 12 mm rod stands up to splash zones that pit painted minis. As a working figure, count on close to 241 N of real push at 0.5 MPa; for vertical lifts that equals roughly 20 kg with a 2:1 safety margin. Magnets are built in on every MA cylinder, letting CMSG, DMSG or EMSG switches clip straight on. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.

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 MACJ32X225-20S Is Used
Tote-lane divider gate
Gates small totes between conveyor lanes; 402 N pushes even a loaded tote path, and the 20 mm trim tunes the stop face to the lane edge.
Battery-bay wash stop
The stainless body tolerates the acidic washdown corner of a forklift battery bay while cushioning the 225 mm stop travel.
Light riveting press stop
Sets a 20 mm-tunable bottom position on a bench riveting press; the 345.6 N pull side retracts the head briskly at 0.5 MPa.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X225-20S the Right Cylinder?
The 25 mm bore (245 N push) and the 50 mm bore (981 N) bracket this size; pick 32 mm when 402 N at 0.5 MPa matches the load. Remember the adjuster sets an extend end stop only - it will not hold position if air is lost, so use a valve circuit for holding. FA flange and LB foot are available, with I or Y rod knuckles for pivot loads. On a 225 mm stroke, keep the load guided to avoid bending moments on the rod.
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 MACJ32X225-20S FAQ
Rated push 402 N / pull 345.6 N at 0.5 MPa, or 563 N / 483.8 N at 0.7 MPa, with an 82 kgf theoretical max at 1.0 MPa from the 32 mm bore. Feed it 0.15-1.0 MPa (22-145 psi) through the 1/8" ports and expect 30-800 mm/s.
The variable air cushion at each end is set with a needle valve, letting you run 30-800 mm/s on heavy or fast cycles without slamming the aluminium covers. Pair that with the hard-chrome 12 mm rod: keep side loads off it over the 225 mm travel, use an I or Y knuckle for pivoting tools, and the chrome surface resists scoring in dusty or damp cells.
