Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X100-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X100-75S 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 MACJ32X100-75S
Where one cylinder must serve several stroke lengths, the MACJ32X100-75S covers them all: a double-acting 32 mm round-body mini whose extend stroke shortens anywhere inside a 75 mm window, while a variable air cushion at both ends tames end-of-stroke shock. Force at 0.5 MPa is 402 N extending and 345.6 N retracting.
The barrel is stainless steel rolled into aluminium covers around a hard-chrome plated rod, so washdown bays and humid plants are fair game. A piston magnet is included as standard on every unit, ready for CMSG, DMSG or EMSG switches. For real-world sizing, count on about 241 N of useful push at 0.5 MPa - enough to raise an approximately 20 kg load vertically when you keep a 2:1 lift 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 MACJ32X100-75S Is Used
Changeover on a filling carousel
One cylinder handles 25 ml and 500 ml formats after a screw turn; the 75 mm window spans the full nozzle retraction spread.
Drill depth stop on a panel line
Sets hole depth on MDF panels without changing tooling; cushioning both ends stops the spindle head rebounding at the bottom.
Kick-off at a pack inspection station
Nudges faulty packs off a checkweigher belt; 402 N at 0.5 MPa shifts even doubles, and the magnet trips the reject-count sensor.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X100-75S the Right Cylinder?
At bore 32 the step either side matters: bore 25 manages 245.3 N push at 0.5 MPa and bore 40 delivers 628.3 N push at 0.5 MPa, so verify 402 N is what your tooling needs. Because 75 mm of the stroke can be consumed by the mechanical trim, check that remaining travel still clears your fixture; the adjuster sets end of extend only and will not hold a load against a pressure loss. Choose FA flange or LB foot, add I or Y knuckles where the joint must pivot, and rely on the standard magnet for sensing.
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 MACJ32X100-75S FAQ
At 0.5 MPa: 402.2 N push and 345.6 N pull. At 0.7 MPa: 563.0 N push and 483.8 N pull. Maximum theoretical force is 82 kgf at 1.0 MPa. Supply air between 0.15-1.0 MPa (22-145 psi) and cycle at 30-800 mm/s; proof pressure is 1.5 MPa (215 psi).
No - the 75 mm adjuster is a mechanical stop that shortens the extend stroke, so on air loss the rod still drifts and any suspended load must be supported separately. For position detection, the standard built-in magnet works with CMSG, DMSG and EMSG switches anywhere along the stainless barrel.
