Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X80-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X80-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 80mm 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 MACJ32X80-40S
Built around a 32 mm stainless barrel rolled onto aluminium covers, the MACJ32X80-40S delivers 402 N forward and 346 N back at 0.5 MPa (563 N at 0.7 MPa), with an extend stroke trimmed anywhere in its 40 mm window. Double-acting and dual-cushioned, it soaks up end-of-stroke shock so faster cycles do not hammer the covers.
The hard-chrome plated 12 mm rod resists scoring under side loads, and because the magnet is a standard fitting, CMSG or EMSG switches drop straight on. Think of the 402 N rating as about 20 kg of vertical lift with a 2:1 margin, which is a real part weight you can match against when specifying.

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 MACJ32X80-40S Is Used
Sample tray shuttle in lab automation
Moves sample trays between stations; a 40 mm trim dials in exact docking and the built-in magnet feeds DMSG position signals to the controller.
Small press fixture clamp
Clamps jig plates before a light staking press; about 241 N of working force at 0.5 MPa holds parts square through the forming cycle.
Divider blade on food conveyors
Stainless barrel and chromed rod cope with humid, sprayed areas while the dual cushions keep blade chatter down at each reversal.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X80-40S the Right Cylinder?
Size down to the 25 mm MACJ (245 N push at 0.5 MPa) when the load is light, or up to the 40 mm bore (628 N) for heavier work at the same pressure. The stop screw trims the extend stroke; it is not a mid-stroke lock, so a dropped supply still lets the piston drift. Magnet is built in, so CMSG/DMSG/EMSG sensing needs no piston options, and FA or LB mountings bolt straight to standard plates.
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 MACJ32X80-40S FAQ
Rated 402 N push and 346 N pull at 0.5 MPa, rising to 563 N push and 484 N pull at 0.7 MPa; the 1.0 MPa theoretical ceiling is 82 kgf. The extend stop adjusts across a 40 mm window and cushioning is variable at both ends.
The piston magnet is standard, so CMSG, DMSG or EMSG switches fit without options. Mounting choices include FA flange, LB foot, plus I and Y rod knuckles, and a 1/8-inch port feeds the 32 mm bore.
