Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X65-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X65-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 65mm 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 MACJ32X65-30S
Shorten the extend stroke on the machine, not in the order book: the MACJ32X65-30S is a double-acting, adjustable-stroke mini cylinder with a variable air cushion, and its 30 mm adjuster lets the 65 mm stroke be trimmed down to 35 mm by a stop screw. At 0.5 MPa it pushes 402 N and pulls 346 N, climbing to 563 N of push at 0.7 MPa, across a 0.15-1.0 MPa (22-145 psi) supply at 30-800 mm/s.
The round body is a riveted stainless barrel with a 20 um hard-chrome plated carbon-steel rod, so it tolerates washdown and humid air far better than painted minis. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight on. For sizing, treat about 241 N as the practical working force at 0.5 MPa, and with a 2:1 margin this bore lifts roughly 20 kg vertically.

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 MACJ32X65-30S Is Used
Snack-line gate stop
Stops product flow at a checkweigher on a snack packaging line; the 30 mm window absorbs last-minute timing changes and the cushion quiets the gate at 65 mm travel.
PCB pallet lift-pin
Raises SMT pallets onto locating pins in an electronics fixture; about 20 kg vertical capacity at a 2:1 margin matches typical loaded pallet weights.
Snap-clip press
Presses automotive trim clips home in a small bench jig; 402 N at 0.5 MPa is comfortable for clip insertion forces under 240 N.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X65-30S the Right Cylinder?
Compare force classes before committing: bore 25 in this series manages 245 N of push at 0.5 MPa, while bore 40 reaches 628 N - the MACJ32's 402 N sits between for medium clamps and gates. The stop screw shortens the extend stroke only; it is a mechanical end stop, so if air is lost the piston can still drift and the position is not held.
Mount on FA flange or LB foot, add an I or Y rod knuckle where the load pivots, and note the adjustable version has no SDB or back-cover code. Ports are 1/8" with an M10x1.25 male rod thread.
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 MACJ32X65-30S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa push rises to 563.0 N (pull 483.8 N). The theoretical maximum at 1.0 MPa is 82 kgf, on a 0.15-1.0 MPa (22-145 psi) supply with 1.5 MPa (215 psi) proof pressure.
The barrel is stainless steel and the rod is carbon steel with a 20 um hard-chrome plate, so splash, humidity and mild washdown do not quickly ruin the cylinder the way they corrode painted mini bodies. Aluminium-alloy covers are riveted on for a sealed round body.
