Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X30-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X30-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 30mm 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 MACJ25X30-10S
A 30 mm stroke with a 10 mm trim window makes the MACJ25X30-10S a fit for compact clamping and gauging stations where the endpoint must be dialed in by hand. Air drives the piston both ways - it is double-acting - and a variable air cushion at each port softens the short travel across 30-800 mm/s. At 0.5 MPa it delivers 245.3 N extend and 206.1 N retract.
The rolled stainless barrel and hard-chrome carbon-steel rod stand up to coolant splash that would ruin painted mini cylinders. With typical derating, plan on about 147 N of working push, enough to seat or lift roughly 12 kg vertically against a 2:1 margin. Every MA cylinder includes the magnet as standard, so CMSG / DMSG / EMSG switches snap on at commissioning; pressure runs 0.15-1.0 MPa (22-145 psi).

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 MACJ25X30-10S Is Used
Crimp terminal staking on a wire bench
Staking a crimp barrel with a 30 mm stamp: 245.3 N at 0.5 MPa seats the joint, and the 10 mm trim sets exact bottom position per terminal type.
Fixture clamp on a CNC jig
Clamping small aluminium blanks between cuts; the short stroke keeps the clamp clear of the spindle, and the cushion prevents bounce on the part surface.
Connector seat check on an electronics line
Probing whether a connector is fully seated: the 10 mm window fine-tunes probe travel, and the built-in magnet reports positions to the PLC via CMSG switches.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X30-10S the Right Cylinder?
At 245.3 N of push (0.5 MPa) the 25 mm bore is the middle choice - the 20 mm bore manages 157.0 N and the 32 mm bore 402.2 N. With only 30 mm of travel, side-load risk is low, yet a guide is still wise on any off-centre part.
FA flange and LB foot options fit most small fixtures, and the standard magnet drives CMSG, DMSG or EMSG switches directly. The 10 mm adjuster trims the extend endpoint; it will not keep the rod parked once air is removed.
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 MACJ25X30-10S FAQ
It develops 245.3 N push and 206.1 N pull at 0.5 MPa, rising to 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical ceiling of 50.0 kgf at 1.0 MPa. Ports are 1/8" and the 10 mm rod carries an M10x1.25 male thread. The -10 suffix marks a 10 mm adjustable window on the extend stroke.
Pick FA flange or LB foot mounting, with I or Y rod knuckles where the load articulates. The stop screw on the head shortens the extend stroke anywhere within the 10 mm window - a mechanical limit for dialing in clamp or gauge positions. It is an endpoint stop only, so never count on it to hold a load once air pressure is gone.
