Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 75mm 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 MACJ32X75-40S
Built for lines that get re-tooled often, this 32 mm bore cylinder trims its extend stroke across a 40 mm band via the external stop screw and cushions both travel ends with variable air. Rated 402 N out and 346 N in at 0.5 MPa, it holds an 82 kgf theoretical ceiling at 1.0 MPa.
A rolling-packed body - stainless barrel, aluminium end covers, steel block - keeps the footprint slim while resisting the rust that kills painted minis near washdown bays. The 12 mm hard-chrome rod rides on a grease-storing two-way seal, stretching service intervals. The magnet is standard equipment, so CMSG, DMSG and EMSG switches mount without ordering a special piston.

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 MACJ32X75-40S Is Used
Blister-card clinch station
Presses foil lids onto pharma trays; cushioned stops protect the 82 kgf-class tooling at cycle speeds up to 800 mm/s.
Kiosk drawer eject
Ejects receipt drawers in outdoor payment kiosks, where the stainless barrel shrugs off rain and dust year-round.
Bottling-guide rail adjustment
Offsets guide rails per bottle SKU using the 40 mm trim window instead of swapping spacers between changeovers.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-40S the Right Cylinder?
Neighbors in the range: 25 mm bore gives 245 N at 0.5 MPa and 40 mm bore gives 628 N, so this unit's 402 N covers the middle ground. If you lift parts vertically, halve the 41 kg theoretical lift for a 2:1 margin and spec loads around 20 kg. FA flange or LB foot mounting, plus I and Y rod knuckles for linkages; adjustable models omit the SDB and back-cover codes. The wide 40 mm trim window suits fixtures re-gauged between product changeovers.
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 MACJ32X75-40S FAQ
At 0.5 MPa: 402 N extend, 345.6 N retract. At 0.7 MPa: 563 N extend, 483.8 N retract. Theoretical peak: 82 kgf at 1.0 MPa. Supply range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
Yes. The stop screw shortens the extend stroke anywhere inside the ordered 40 mm window; it cannot lengthen travel beyond 75 mm. Note it acts as an end stop only - on air loss the rod drifts rather than locking in place.
