Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X100-75S
The AirTAC MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X100-75S is a genuine double acting, double rod, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 100mm 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 MACJ25X100-75S
A 75 mm trim window makes the MACJ25X100-75S the most tunable 25 mm bore MA in this range: the extend stroke can be set anywhere up to 100 mm with the external stop screw, and the variable air cushion absorbs the landing at both ends.
Because the aluminium covers are rolled onto the barrel rather than tied, the body sheds mild corrosion and survives washdown that swells painted-steel minis in damp or food-area spots.

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 (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 kgf |
MAJ / MACJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X100-75S Is Used
Bottle-line stopper gate
A gate that halts PET bottles at a filler infeed, its dwell point set on the machine with the 75 mm stop screw instead of a cylinder change.
Bench fixture clamp
Clamps aluminium brackets on a machining bench; roughly 147 N of working thrust at 0.5 MPa holds light parts without crushing.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X100-75S the Right Cylinder?
If 245.3 N at 0.5 MPa oversizes your task, the MACJ20 delivers 157 N in a 20 mm bore; when you need more, the MACJ32 reaches 402.2 N. The stop screw trims the extend stroke within the 75 mm window - it is a mechanical end stop, not a lock, so the rod will still drift if air is lost. Match an FA flange or LB foot, add I or Y rod knuckles if the linkage needs them, and CMSG/DMSG/EMSG switches clip straight onto the standard magnet. Operating range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
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 MACJ25X100-75S FAQ
Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed runs 30-800 mm/s.
No. Every MA-series cylinder ships with the magnet built in, so CMSG, DMSG or EMSG switches mount directly on the stainless barrel for end-of-stroke signalling. The riveted round body and hard-chrome plated rod also tolerate washdown, and FA flange or LB foot mounts bolt on without adapters.
