Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-75S 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 MACJ32X75-75S
AirTAC's MACJ32X75-75S carries the widest 75 mm trim window on a 75 mm stroke, so the whole extend travel can be shortened on the machine without swapping cylinders. The MA-series build is a riveted stainless round barrel with a hard-chrome plated 12 mm rod - no external bolts to loosen, no paint to chip. Double-acting with a variable cushion at each end, it pushes 402 N and pulls 345 N at 0.5 MPa.
The adjuster acts as a positive mechanical end stop, trimming only the extend stroke; it never lengthens travel beyond 75 mm and it does not lock the piston if air pressure drops. For sizing, keep real work near 241 N - about 60% of the 0.5 MPa push - and the cylinder will run cooler and last longer through its 30-800 mm/s speed band at 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 MACJ32X75-75S Is Used
CNC fixture part ejector
Knocking finished parts off a fixture after cut; the full 75 mm window lets you set the knock-off point per part.
Sorting flap actuator
Tipping a divert flap between two chutes, with cushioned landings keeping the mechanism quiet at speed.
Lab press quick set
A bench-top test press where sample heights change daily - trim the stroke instead of re-shimming the stack.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-75S the Right Cylinder?
Compare on force at 0.5 MPa: the MACJ25 gives 245 N and the MACJ40 gives 628 N, so this 402 N bore sits mid-range for 75 mm travel. If you need the stroke held against a drifting load when the air fails, add a check or pilot valve - the stop screw is for setting position, not for supporting weight. Foot (LB) or flange (FA) mounting, I and Y knuckles available; the standard magnet works with CMSG, DMSG or EMSG switches out of the box.
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 MACJ32X75-75S FAQ
It is double-acting with adjustable stroke and variable air cushion. At 0.5 MPa: 402.2 N push, 345.6 N pull. At 0.7 MPa: 563.0 N push, 483.8 N pull. Maximum theoretical force 82 kgf at 1.0 MPa. Pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, -20 to +70 C, 1/8" port, M10x1.25 male rod thread.
The rolled stainless tube and the 20 um hard-chrome plate on the 12 mm rod resist corrosion far better than painted-steel minis, so the cylinder survives washdown corners, condensation and outdoor splash without flaking or seizing.
