Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X30-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X30-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 30mm 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 MACJ32X30-30S
Short 30 mm strokes with an on-site trim: the MACJ32X30-30S is AirTAC's round-body mini cylinder in double-acting form, with a variable air cushion at each end and an extend stroke you can shorten by up to 30 mm via the external stop screw. At 0.5 MPa the 32 mm bore delivers 402 N on extend, so this frame suits compact clamp-and-latch work rather than long travel. The operating window is 0.15-1.0 MPa (22-145 psi) at speeds of 30-800 mm/s.
The rolling-packed body pairs a stainless-steel barrel with a hard-chrome plated 12 mm rod, so damp or lightly washed areas will not flake the way painted-steel minis do in food or outdoor corners. Size your real work at roughly 241 N per extend stroke at 0.5 MPa - about 60% of the rating - and you keep margin in hand for cushion deceleration. A magnet is built into the piston as standard, so CMSG, DMSG or EMSG switches snap on without any special piston order.

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 MACJ32X30-30S Is Used
Packaging machine latch
Snaps a carton-guard latch closed on a horizontal flow-wrapper; the 402 N extend force at 0.5 MPa sits far above typical latch spring loads.
Drill fixture clamp
Clamps small aluminium brackets in a drill fixture; the 30 mm stroke with up to 30 mm of on-site trim absorbs varying part heights without reordering.
Rotary table index pin
Pushes an index pin into a dividing plate on a rotary indexing table; the dual variable cushions kill the pin's seating shock at speed.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X30-30S the Right Cylinder?
Between bores: the 25 mm MACJ gives 245 N at 0.5 MPa if the load is lighter, while a 40 mm bore steps up to 628 N when you need more push. Both neighbours share the same round-body construction and adjustable cushion. Mount with the FA flange or LB foot; I and Y rod knuckles are available, and note the adjustable version has no SDB or back-cover code. The stop screw sets the extend position only - it is not a mid-stroke lock, so the rod will drift if air is lost.
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 MACJ32X30-30S FAQ
At 0.5 MPa: 402.2 N extend and 345.6 N retract. At 0.7 MPa: 563.0 N extend. The theoretical maximum at 1.0 MPa is 82 kgf. The full pressure band is 0.15-1.0 MPa (22-145 psi), with proof pressure of 1.5 MPa (215 psi).
Yes. The -30 suffix is the adjustable window: an external stop screw shortens the extend stroke on site within that 30 mm range, and the variable air cushion at both ends stays active at whatever position you set. Running at up to 800 mm/s, the cushion soaks up end-of-stroke shock instead of hammering the front cover.
