Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X20-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X20-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 20mm 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 MACJ32X20-20S
Where a fixture needs a stroke dialled in by hand, the MACJ32X20-20S offers up to 20 mm of on-site trim on a double-acting, cushioned mini cylinder. This 32 mm bore delivers 402.2 N of push and 345.6 N of pull at 0.5 MPa, with a theoretical 82 kgf ceiling at 1.0 MPa.
The magnet ships built in as standard, so a CMSG, DMSG or EMSG switch drops straight onto the stainless barrel without a special-order piston. Working from the 0.5 MPa rating, plan jobs around about 241 N and you can still hold a vertical lift of roughly 20 kg with a 2:1 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 MACJ32X20-20S Is Used
Bottle infeed stop
Halts bottles entering a rotary filler using a stroke set precisely within the 20 mm trim range.
Cabinet door latch
Latches washdown control-cabinet doors, the stainless body resisting splash far better than a painted mini.
Probe press fixture
Presses test probes onto PCB pads with repeatable short travel and cushioned touchdown, protecting fine tips.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X20-20S the Right Cylinder?
The MACJ25 at 245.3 N (0.5 MPa push) suits lighter clamps; if your fixture may grow, the MACJ40 gives 628.3 N in the same round format. Keep in mind the trim screw fixes the end of travel only - with air removed, the piston is free to move, so add a separate lock if holding matters. Choose FA flange or LB foot mounting; I and Y rod knuckles accept linkage offsets, and the magnet for CMSG/DMSG/EMSG switches is included on every unit.
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 MACJ32X20-20S FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa they reach 563.0 N and 483.8 N, with 82 kgf theoretical peak at 1.0 MPa. Supply pressure ranges 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
No. Every MACJ32X20-20S carries the magnet as standard, so CMSG, DMSG and EMSG reed or electronic switches mount directly on the barrel and detect end positions without any factory option or extra cost.
