Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X225-100S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X225-100S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 225mm 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 MACJ32X225-100S
With a 100 mm trim window - the widest offered on this series - the MACJ32X225-100S fits machines whose final extend position is decided during commissioning rather than on paper. It is a double-acting round-body cylinder with a variable air cushion at both ends, so 30-800 mm/s travel can stay quick without hammering the covers. At 0.5 MPa the 32 mm bore delivers 402 N of push; at 0.7 MPa that climbs to 563 N.
The stainless barrel with its hard-chrome 12 mm rod tolerates damp, dusty and lightly corrosive surroundings far better than painted minis. For vertical duties: the bore lifts about 41 kg at 0.5 MPa on paper, so budget around 20 kg of payload for a 2:1 margin. Every unit includes a standard magnet that accepts CMSG, DMSG and EMSG switches, and the supply range is 0.15-1.0 MPa (22-145 psi).

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 MACJ32X225-100S Is Used
Semi-auto assembly nest
Commission a 225 mm-stroke clamp once and set its final grip point anywhere within 100 mm using the stop screw; 402 N is ample for plastic housings at 0.5 MPa.
Lab test rig loading
Apply a repeatable 402 N push to sample trays on a materials bench; the cushion trims impact as the platen seats against the fixture.
Case eject on checkweigher
Kicks rejected cartons off the belt; the stainless body handles the damp, dusty conveyor environment and the standard magnet runs a DMSG switch for stroke-done confirmation.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X225-100S the Right Cylinder?
Below it in the range, a 20 mm bore yields 157 N; above, a 50 mm bore reaches 981 N, so the 32 mm class at 402 N covers mid-range clamping and pushing. Keep in mind the trim screw only sets the extend end position - it cannot hold a load if air pressure drops. FA flange and LB foot are the fixed mounts; I and Y knuckles suit swivelling tooling. Over 225 mm of travel, avoid side loading or add external guides to spare 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 MACJ32X225-100S FAQ
The numbers: push 402 N and pull 345.6 N at 0.5 MPa; push 563 N and pull 483.8 N at 0.7 MPa; theoretical maximum 82 kgf at 1.0 MPa for this 32 mm bore. Add the 1/8" port, speeds of 30-800 mm/s, and a 0.15-1.0 MPa (22-145 psi) supply window.
The rolling-packed body pairs a high-precision stainless barrel with aluminium-alloy covers and a hard-chrome plated 12 mm carbon-steel rod (20 um chrome), so mild corrosion, coolant mist and occasional hose-down are non-events compared with painted-steel minis. Wipe it down and grease retention in the heterogeneous piston seal keeps it running.
