Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X200-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X200-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 200mm 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 MACJ32X200-40S
Need the extend stroke dialled in at the machine instead of fixed at order time? The MACJ32X200-40S does exactly that: an external stop screw shortens the extend stroke anywhere within the 40 mm window, while the double-acting piston and a variable air cushion at both ends keep motion smooth from 30 to 800 mm/s.
Under the riveted stainless barrel sits a 12 mm hard-chrome rod, so mild washdown and outdoor humidity are no threat to the body. Force at 0.5 MPa is 402 N push; the 41 kg vertical-lift equivalent, halved for margin, means roughly 20 kg can be raised with a 2:1 safety factor. Pressure spans 0.15-1.0 MPa (22-145 psi), proof is 1.5 MPa (215 psi), and the standard magnet accepts CMSG / DMSG / EMSG switches.

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 MACJ32X200-40S Is Used
Part stopper on a pallet transfer line
Pallets up to 20 kg meet a raised stop blade; the 40 mm window sets the blade stroke so sensor-triggered stops land in the same spot every cycle.
Bench-top press for connector crimping
Roughly 241 N of practical working force suits light crimp and stake operations; the adjustable stroke handles varied part heights without swapping tooling.
Lid press on a food tub sealer
The stainless round body and hard-chrome rod shrug off the damp, wash-prone zone around a tub sealer, pressing snap-on lids with cushioned, repeatable force.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X200-40S the Right Cylinder?
Compare before you commit: the 25 mm MACJ makes 245 N at 0.5 MPa and the 40 mm makes 628 N, so this 32 mm size at 402 N is the middle path. Its 40 mm trim window shortens the extend stroke only - it cannot lengthen past the ordered 200 mm - and remember the adjuster stops the piston but does not hold a load when air is lost.
Switch feedback costs nothing extra here since the magnet is standard; just pick CMSG, DMSG or EMSG to suit your PLC input. FA flange and LB foot mounts, plus I and Y knuckles, cover most fixings.
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 MACJ32X200-40S FAQ
Push at 0.5 MPa is 402 N (402.2 N) and pull 346 N (345.6 N); at 0.7 MPa expect 563 N push and 484 N pull; theoretical maximum is 82 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, and the extend stroke trims across a 40 mm window.
It behaves as a mechanical end stop for the extend stroke only. It sets where the rod reaches full extension within the 40 mm window, but it is not a load-holding brake - with air lost, an external load can still push the piston, so fit a locking valve where holding is critical.
