Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X225-100S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X225-100S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 225mm 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 MACJ25X225-100S
The widest trim band in the MACJ range - 100 mm - makes this 225 mm model the pick when one cylinder must serve several product lengths on the same machine. It is double-acting with a variable air cushion at both ends, pushing 245.3 N and pulling 206.1 N at 0.5 MPa, cycling at 30-800 mm/s from a 0.15-1.0 MPa (22-145 psi) supply.
Construction is AirTAC's rolling-packed MA body: a stainless-steel barrel with aluminium covers riveted on, plus a hard-chrome rod that resists washdown and outdoor damp better than painted minis. Practical sizing tip: count on about 147 N of working push at 0.5 MPa, close to a 12 kg vertical lift, rather than the full rating. The magnet comes standard, so CMSG, DMSG or EMSG switches mount without ordering extras.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MACJ25X225-100S Is Used
Case depth adjuster
One cylinder serves tall and short cartons: trim the extend stop across 100 mm as case heights change on the packer.
Test rig actuator
Applying about 147 N to lever arms or sample coupons in a small QA bench, with cushions smoothing both landings.
Cooler door pusher
Nudging tote bins onto a take-away conveyor, the 225 mm travel clears the rack face while the stainless barrel handles chiller humidity.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X225-100S the Right Cylinder?
For a 225 mm reach at this thrust class, compare the 20 mm bore (157.0 N push at 0.5 MPa) against the 32 mm bore (402.2 N) before settling on 25 mm. Long travels like this are more sensitive to side load, so guide the load externally or fit I or Y knuckles; FA flange and LB foot mounts are available. Note the stop screw is an extend limit only, not a position lock when air fails.
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 MACJ25X225-100S FAQ
Bore 25 mm: push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; theoretical maximum 50.0 kgf at 1.0 MPa. Supply range 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi).
Yes - the piston magnet is built in as standard on every MA cylinder, so CMSG, DMSG and EMSG switch types drop onto the stainless barrel whenever your control scheme needs end-of-stroke signals.
