Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X180-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X180-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 180mm 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 MACJ32X180-75S
Built on a riveted stainless barrel with a hard-chrome plated 12 mm rod, the MACJ32X180-75S stands up to washdown and humid plant air where painted minis rust through. Its 75 mm adjust window means the 180 mm extend stroke can be cut back anywhere on the machine, no cylinder swap needed.
Double-acting with a variable cushion at both ends, this bore delivers 402 N push and 346 N pull at 0.5 MPa; budget around 241 N for real work at that pressure. The full theoretical rating tops out at 82 kgf at 1.0 MPa. Every unit ships with the magnet in - CMSG, DMSG and EMSG switches mount without special ordering.

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 MACJ32X180-75S Is Used
Stopper gate on an assembly conveyor
Drops and raises a stop blade between stations; the 75 mm window absorbs late fixture changes on mixed-model lines.
Sample tray index in a lab autosampler
Lifts sample racks between wash and read stations; about 41 kgf theoretical at 0.5 MPa covers a fully loaded tray with margin.
Carton kicker at a sortation spur
Kicks parcels off the main belt; dual air cushions keep 800 mm/s cycles from cracking the aluminium covers.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X180-75S the Right Cylinder?
Compare against MACJ25 (245 N push at 0.5 MPa) for lighter duties or MACJ40 (628 N) if loads climb. A 180 mm stroke plus side load is a recipe for bent rods - guide externally or add an I or Y rod knuckle. The trim screw is an extend-side end stop, not a brake: under air loss the piston drifts, so add a separate valve or lock where holding matters.
FA flange and LB foot brackets, plus I/Y knuckles, cover the mounting; 1/8" ports on this bore; speed range 30-800 mm/s.
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 MACJ32X180-75S FAQ
Push is 402 N and pull 346 N at 0.5 MPa; at 0.7 MPa expect 563 N push and 484 N pull; theoretical peak at 1.0 MPa is 82 kgf. Pressure runs 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
Yes - every MA-series cylinder carries a built-in piston magnet as standard, so CMSG, DMSG or EMSG reed switches retrofit directly for end-of-stroke signalling. No special piston or factory option is needed.
