Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-30S 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 MACJ32X175-30S
A 30 mm trimming window on a 175 mm extend stroke makes the MACJ32X175-30S a fit for packaging and assembly stations that need one cylinder to serve several product sizes. The cylinder is double acting and moves on air in both directions, with a variable air cushion at each end that soaks up stop shock so you can run faster or carry heavier loads without hammering the covers. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N; the riveted stainless-steel barrel and hard-chrome plated rod shrug off washdown and humidity where painted mini cylinders rust early. Plan on roughly 241 N of usable work at 0.5 MPa (about 60 percent of the rating) and you will size the application with margin to spare.
The built-in magnet ships as standard, so CMSG, DMSG or EMSG switches clip on for end-of-stroke signalling without a special-order piston. Adjusting the stop screw shortens the extend stroke within the 30 mm window; it is a mechanical end stop, so on air loss the rod can still drift and it should never be relied on as a brake.

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 MACJ32X175-30S Is Used
Multi-size carton stop
A packaging line running cartons of several heights uses the 30 mm window to re-stop the 175 mm stroke per product, with no re-plumbing needed.
Small part press-fit
Pressing bushings into housings on an assembly bench: 402 N at 0.5 MPa (about 41 kg of push) suits light interference fits, and the cushion eases the landing.
Gated part ejection
A CMSG switch on the built-in magnet confirms the rod is back before the next part feeds; the 175 mm throw clears parts off a small conveyor.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-30S the Right Cylinder?
Compare forces at 0.5 MPa: the 25 mm bore in this series manages 245.3 N push, so if your load sits under about 150 N that smaller cylinder saves space; step up to the 40 mm bore for 628.3 N push when the job grows. The 32 mm bore at 402.2 N push covers mid-range pick-and-place work with a healthy margin. A 175 mm stroke on a 12 mm rod wants alignment care - keep side loads off the rod or add external guiding to protect the bushings. FA flange and LB foot mounts plus I and Y rod knuckles are available, and the standard magnet pairs with CMSG / DMSG / EMSG switches for position feedback.
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 MACJ32X175-30S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa that rises to 563.0 N push and 483.8 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
An external stop screw trims the extend stroke anywhere within the 30 mm window below the ordered 175 mm; the stop is a limit, not a load-holding lock. A variable air cushion at both ends lets you slow the last millimetres of travel, so the 12 mm rod arrives without banging the covers.
