Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X40-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X40-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MACJ32X40-30S
Part of AirTAC's riveted round-body MA family, MACJ32X40-30S carries a 30 mm adjustable window on its extend stroke, a double-acting piston and a variable cushion at each end. Output at 0.5 MPa is 402.2 N on push and 345.6 N on pull, a solid mid-class force for clamping and positioning.
The stainless tube resists the coolant mist and occasional hose-down common around machine tools, while the two-way piston seal stores grease for long service life. Every unit ships magnet-equipped as standard, so CMSG, DMSG and EMSG switches drop straight on. In practice, count on roughly 241 N of usable push at 0.5 MPa once you leave margin for friction and load swings.

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 MACJ32X40-30S Is Used
Vial capping head, lab automation
Caps sample vials with a controlled 30 mm trim range; the cushion prevents glass-to-metal shock as the cap seats.
Fixture clamp on a machining line
Clamps workpieces before milling, using 402.2 N at 0.5 MPa and a magnet switch to prove the clamped position.
Sorting chute pusher
Redirects cartons between lanes on a distribution sorter, cycling anywhere from 30 to 800 mm/s without cover hammer.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X40-30S the Right Cylinder?
Step down to bore 25 if 245.3 N at 0.5 MPa is enough, or up to bore 40 for 628.3 N; the 32 mm bore splits the difference with 402.2 N. Mounting spans FA flange, LB foot and I or Y rod knuckles, and the 1/8" port suits standard fittings. Because the adjuster is an end stop rather than a holding device, add a check valve or external lock if the application must stay put when air fails - it will not park a load on its own.
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 MACJ32X40-30S FAQ
Rated output at 0.5 MPa is 402.2 N on extension and 345.6 N on retraction. At 0.7 MPa the pair becomes 563.0 N and 483.8 N, and the bore theoretically develops 82 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with speeds of 30-800 mm/s.
Choose FA flange or LB foot mounting, with I or Y rod knuckles where the load articulates. The 1/8" air port takes common push-in or threaded fittings, the rod is 12 mm with an M10x1.25 male thread, and the magnet for position switches is fitted as standard.
