Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X100-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X100-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 100mm 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 MACJ32X100-30S
A 32 mm double-acting round-body mini cylinder with an adjustable extend stroke and a variable air cushion at both ends, the MACJ32X100-30S lets you trim the extend stroke by up to 30 mm on site without swapping the part. Push force reaches 402 N at 0.5 MPa (563 N at 0.7 MPa), pulling back at 345.6 N.
The stainless-steel barrel and hard-chrome plated 12 mm rod shrug off washdown and humidity better than painted minis, while the riveted aluminium covers keep the rolled body sealed. Every unit ships with a built-in magnet, so CMSG, DMSG or EMSG switches mount straight on. In practice, plan around 241 N of usable working force at 0.5 MPa, enough to lift roughly 20 kg vertically with a 2:1 margin.

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 MACJ32X100-30S Is Used
Pouch gap gate on a VFFS infeed
Gates snack pouches into a vertical form-fill-seal chain; the 30 mm trim lets operators fine-set the gate opening after changeover.
Case stop on a carton line
Stops 5 kg cartons arriving at 40 m/min; the variable cushion at both ends removes the bang at each stop so the sensor count stays accurate.
Bench fixture clamp
Clamps aluminium brackets during deburring; the rolled stainless body tolerates coolant mist that swells painted mini cylinders.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X100-30S the Right Cylinder?
Pick this bore when your load sits between the 25 mm size (245 N push at 0.5 MPa) and the 40 mm size (628 N push at 0.5 MPa); at 32 mm you get 402 N forward and 345.6 N back at 0.5 MPa. The 30 mm window shortens the extend stroke only - the stop screw is an end stop, not a mid-stroke lock, so on air loss the rod still drifts. FA flange or LB foot mounting, I and Y rod knuckles, and the magnet comes fitted as standard.
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 MACJ32X100-30S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa the figures rise to 563.0 N forward and 483.8 N back; the theoretical ceiling at 1.0 MPa is 82 kgf. Port size is 1/8", the rod is 12 mm with an M10x1.25 male thread, speed runs 30-800 mm/s across 0.15-1.0 MPa (22-145 psi), and proof pressure is 1.5 MPa (215 psi).
An external stop screw shortens the extend stroke by up to 30 mm within the ordered window; it cannot lengthen the stroke past 100 mm. Because the adjuster is a mechanical end stop rather than a lock, use the built-in magnet with a CMSG or DMSG switch for position feedback.
