Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-50S 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 MACJ32X75-50S
With a 50 mm trim window, the MACJ32X75-50S lets you dial the extend stroke anywhere up to 75 mm after the cylinder is plumbed in. It is a double-acting round-body mini cylinder in AirTAC's MA family: stainless-steel barrel, hard-chrome plated 12 mm rod, rolled aluminium covers, and a variable air cushion at both ends. Push force reaches 402 N at 0.5 MPa (563 N at 0.7 MPa), with 345 N back on the return stroke.
Because the riveted stainless tube shrugs off washdown and mild corrosion, it holds up in damp food and packaging areas where painted minis rust. At 0.5 MPa the full rating converts to roughly 41 kg of vertical lift, so a small lifting toggle or gripper arm sized under that stays comfortably in class. Speed range is 30-800 mm/s over 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 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 MACJ32X75-50S Is Used
Small stamping bench punch
A 75 mm punch stroke on a light die, trimmed down 25 mm with the adjuster when a shallower form is run.
Packaging line gate pusher
Swinging or pushing cartons off a conveyor; the cushion softens each stop even at the 800 mm/s top speed.
Dial table part stop
Setting an index-table stop screw by trial - the 50 mm window covers several part heights without re-plumbing.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-50S the Right Cylinder?
For 75 mm of travel, 402 N at 0.5 MPa is AirTAC's MACJ25 territory at 245 N push, so step down if the load is light; the MACJ40 pushes 628 N if you want margin for friction or faster cycles. The 50 mm adjuster is a mechanical stop that shortens the extend stroke only - it is not a mid-stroke lock, and the rod still drifts if air is lost, so park loads on a checked valve or a separate stop. Mount with the FA flange or LB foot, add I or Y rod knuckles for misalignment, and the standard magnet picks up CMSG, DMSG or EMSG switches.
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 MACJ32X75-50S FAQ
Double-acting with adjustable stroke and a variable cushion at both ends: 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, up to 82 kgf theoretical at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, temperature -20 to +70 C, 1/8" port, M10x1.25 male rod thread.
Yes - every MACJ ships with the piston magnet as standard, so CMSG, DMSG or EMSG reed switches clip straight onto the barrel for end-of-stroke signalling, no special-order piston needed.
