Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 175mm 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 MACJ32X175-40S
Plants that hose down equipment between shifts are exactly where the MACJ32X175-40S earns its keep. The round stainless barrel is riveted to aluminium covers over a hard-chrome plated rod, so mild corrosion and condensation do not flake paint or seize a bore the way they do on coated minis. Double acting with a variable air cushion at both ends, it pushes 402.2 N and pulls 345.6 N at 0.5 MPa. The 40 mm adjuster lets you set the extend stop anywhere in a 40 mm band under the 175 mm stroke, which in vertical terms means the rod can lift about 41 kg at 0.5 MPa - halve that to roughly 20 kg and you have a 2:1 margin for a real part.
Sizing the stop as a position limit matters here: it is not a mid-stroke lock, and with air pressure gone the piston will still settle, so carry the load by another means if drift is unacceptable. The magnet is standard equipment, so DMSG or EMSG switches drop on for position feedback. FA flange and LB foot mounts, plus I and Y rod knuckles, complete the mounting set.

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 MACJ32X175-40S Is Used
Dairy filler gate
A gate on a milk-filling line that is hosed down daily; the stainless barrel and chrome rod resist the wet chemistry that ruins painted minis.
Tray diverting on washdown conveyors
Pushing trays between lanes needs about 240 N of real force at 0.5 MPa; the 40 mm window adapts the divert point to new tray formats.
Rinse-station lid lift
Raising lids over a rinse tank: the 175 mm opening clears tall vessels and the variable cushion keeps the lid from slamming at the top.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-40S the Right Cylinder?
Against neighbours at 0.5 MPa: the 25 mm bore pushes 245.3 N, this 32 mm bore pushes 402.2 N, and the 40 mm bore pushes 628.3 N, so 32 mm is the middle choice for diverting and lifting in the 150-250 N working range. On a 175 mm stroke the 12 mm rod is long enough to care about alignment - keep side loads off it or add external guiding, and consider an I or Y rod knuckle to soak up small misalignment. FA flange and LB foot bases mount the body; the standard magnet pairs with DMSG or EMSG switches without special ordering.
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 MACJ32X175-40S FAQ
Bore 32 gives 402.2 N push and 345.6 N pull at 0.5 MPa, climbing to 563.0 N push and 483.8 N pull at 0.7 MPa. Peak theoretical force is 82 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi) and speed can run 30-800 mm/s.
Yes - every MA-series cylinder leaves the factory with the piston magnet built in as standard, at no extra option code. CMSG, DMSG and EMSG switches mount directly on the stainless barrel for extend and retract signalling.
