Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X125-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X125-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 125mm 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 MACJ32X125-30S
Adjustability is the selling point here: order a 125 mm stroke and trim the extend side anywhere from 95 to 125 mm with the external screw, so one MACJ32X125-30S serves several station spacings on a machine frame. Double-acting with a variable cushion at both ends, the 32 mm bore produces 402 N of push at 0.5 MPa (72 psi) - enough for clamping jigs, slides and small gates at cycle speeds up to 800 mm/s.
The riveted round body is a stainless-steel tube with rolled aluminium covers, an arrangement that shrugs off the condensation and mild washdown that ruin painted mini cylinders, while the 12 mm hard-chrome rod holds its finish through millions of cycles. Vertical lifting from this bore works out to about 41 kg at 0.5 MPa, so plan on roughly 20 kg per lift with a 2:1 safety factor. Mounting is FA flange or LB foot, and the standard magnet accepts CMSG, DMSG or EMSG switches for end-of-stroke confirmation.

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 MACJ32X125-30S Is Used
Reject chute actuator on a food filler
The 95-125 mm trim drops rejects of any bottle height, and the stainless barrel stands up to caustic foam washdown between shifts.
Index pin on a rotary indexing table
Dial the extend stroke so the pin seats fully in each bushing, with the end cushion damping the snap at 800 mm/s.
Palletizer pusher for shrink-wrapped trays
402 N at 0.5 MPa squares a tray row against the stop, and CMSG switches confirm home position every cycle.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X125-30S the Right Cylinder?
A 25 mm MACJ cylinder gives 245 N at 0.5 MPa, while a 40 mm bore reaches 628 N - pick this 32 mm model when your load sits between those brackets and the 402 N extend force covers it with margin. Remember the -30 adjuster only shortens the extend stroke (95-125 mm); it acts as a mechanical stop, not a brake, so do not count on it to keep a load parked if the air supply drops. FA flange and LB foot mounts plus I or Y knuckles cover most fixturing; on a 125 mm stroke, keep side loads off the rod or the seals will wear early.
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 MACJ32X125-30S FAQ
Push 402 N and pull 345.6 N at 0.5 MPa (72 psi); push 563 N and pull 483.8 N at 0.7 MPa (101 psi); 82 kgf theoretical maximum at 1.0 MPa. Keep continuous loads near 241 N so the cylinder always runs with reserve.
A variable air cushion at each end lets you throttle the last millimetres of travel, so the full 125 mm stroke can decelerate heavy carriers quietly at speeds up to 800 mm/s instead of hammering the rolled covers.
