Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X130-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X130-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 130mm 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 MACJ25X130-30S
Stroke 130 mm inside a bore 25 round body gives this MACJ a longer reach than the usual 125 mm mini, and the -30S suffix adds a 30 mm adjustable window so the extend stroke can be shortened on site to suit the fixture. A variable cushion at each end plus double-acting power means 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with roughly 50 kgf available at the 1.0 MPa theoretical maximum. Air supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
Where painted mini cylinders chalk and rust, the stainless barrel and hard-chrome carbon-steel rod here stand up to splashes, humidity and routine wipe-downs, with covers rolled onto the barrel for a sealed body. Size the job around 147 N - 60 percent of the 0.5 MPa push - which corresponds to lifting about 12 kg vertically with a comfortable margin. A magnet is built into the piston as standard equipment, so CMSG / DMSG / EMSG sensors mount with no ordering surcharge.

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 MACJ25X130-30S Is Used
Carton kicker at a dispatch gate
The 130 mm reach clears a carton lane in one hit, the 30 mm window dials the kick point after chute changes, and 206.1 N pull retracts the kicker fast for the next cycle.
Vial tray lift on a pharma packaging line
Lifts about 12 kg of loaded tray vertically with a 2:1 margin, and the stainless barrel wipes down between batches without losing finish.
Tooling slide on a small assembly press
Fit-and-finish stations re-trim the slide within the 30 mm window as tooling is swapped; the cushions keep the 343.4 N peak (0.7 MPa) from slamming the fixture.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X130-30S the Right Cylinder?
The force ladder runs 157 N (bore 20), 245.3 N (bore 25), 402.2 N (bore 32) at 0.5 MPa; if the clamp or pusher needs more than about 147 N of reliable output, this bore is the minimum sensible pick. Note the 30 mm adjuster is purely a mechanical stop that shortens the extend stroke - it is not a mid-stroke lock, and with air removed the rod still coasts. Bolt it down with an FA flange or LB foot, fit I or Y knuckles where joints pivot, and since 130 mm is a long reach for a 10 mm rod, take side loads on external tooling.
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 MACJ25X130-30S FAQ
Bore 25 double-acting with 130 mm stroke and a 30 mm adjustable window. Forces: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, 50 kgf theoretical at 1.0 MPa. Rod 10 mm, ports 1/8", working pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
The magnet is a standard part of every MACJ piston, so CMSG, DMSG or EMSG switches attach to the stainless barrel with no special order. The stainless construction also tolerates splashes and wipe-downs, making the sensing package well suited to wet or dusty stations.
