Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X40-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X40-10S 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 MACJ32X40-10S
A compact 32 mm bore round-body cylinder for machines that need the forward stroke to stop short of full extension. MACJ32X40-10S is double-acting, with an external stop screw that trims the extend stroke anywhere inside a 10 mm window, plus a variable air cushion at both ends to soak up piston energy. At 0.5 MPa it pushes 402.2 N and pulls 345.6 N.
The riveted stainless barrel and 20 um hard-chrome rod shrug off washdown and humid air that swells painted-steel minis, and the built-in magnet is standard, so CMSG, DMSG or EMSG switches clip on without a special piston. For real-world sizing, allow about 241 N of working effort at 0.5 MPa instead of the full 402.2 N rating.

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 MACJ32X40-10S Is Used
Reject gate on a canning line
The 10 mm trim lets the cylinder kick rejects off the conveyor rail with no overtravel; 402 N at 0.5 MPa moves a lightweight gate with margin to spare.
Bench crimping fixture
Crimps terminals and ferrules in electronics assembly; the dual variable cushion tames end-of-stroke snap at cycle speeds up to 800 mm/s.
Stopper station with part detection
Pairs with a CMSG or DMSG switch to confirm the trimmed forward position on an in-feed stopper before the next station cycles.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X40-10S the Right Cylinder?
Bore 25 delivers 245.3 N at 0.5 MPa and bore 40 reaches 628.3 N, so this 32 mm size covers the mid-range between light ejection and heavier pressing. The stop screw is purely an end stop: with air lost the rod still drifts, so treat it as a position trim, never a load park. Mount it FA flange or LB foot, add I or Y rod knuckles if the load pivots, and plumb the 1/8" port - a 40 mm stroke keeps side-load worries negligible.
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 MACJ32X40-10S FAQ
At 0.5 MPa the cylinder pushes 402.2 N and pulls 345.6 N; at 0.7 MPa those figures rise to 563.0 N and 483.8 N. The theoretical maximum is 82 kgf at 1.0 MPa, and the working pressure band is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
The barrel is stainless steel rolled onto aluminium covers, and the carbon-steel rod carries a 20 um hard-chrome plate, so condensation, coolant mist and washdown cause far less trouble than on painted mini cylinders. Pressure ports are 1/8".
