About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X25-30S
For fixture work in cramped dies, the MAJ32X25-30S is hard to beat: 32 mm bore, 25 mm base stroke, and a stop screw that lets you dial the extend stroke down across a 30 mm adjust window without swapping cylinders. It pushes 402.2 N and pulls 345.6 N at 0.5 MPa, rising to 563.0 N at 0.7 MPa.
Count on roughly 241 N of usable push at 0.5 MPa if you want service margin rather than running at the limit. The stainless-steel round barrel and hard-chrome carbon-steel rod (20 um plating) tolerate coolants and humidity that shorten the life of painted mini cylinders, while the riveted aluminium covers keep the footprint tight. A fixed anti-impact pad cushions each stroke end - deceleration only, not an adjustable air cushion like the MAC family.

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 MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X25-30S Is Used
Welding fixture hold-down
Dial the extend stroke across the 30 mm window to clamp varying sheet thicknesses with up to 563 N at 0.7 MPa.
Die marker / punch advance
A fixed 25 mm base stroke with on-site trimming replaces multiple short-stroke cylinders in stamping and marking dies.
Bottle capping press
At 0.5 MPa the bore's 402 N push seats caps on lab reagent bottles; the built-in magnet drives a CMSG switch for jam detection.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X25-30S the Right Cylinder?
If 402 N of push at 0.5 MPa is more than the job needs, the 25 mm bore delivers 245.3 N; if it falls short, the 40 mm bore reaches 628.3 N. For lifting, the 32 mm bore manages about 41 kg vertically at 0.5 MPa - plan 20 kg for a 2:1 margin. Mount via FA flange, LB foot or I / Y knuckles; every unit ships with the magnet already fitted for CMSG / DMSG / EMSG switches. Note the adjuster limits extend travel only; with air lost the piston is free to move.
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 Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X25-30S FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa expect 563.0 N push and 483.8 N pull. The theoretical ceiling is 82 kgf at 1.0 MPa. Operating band is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
No. Each MAJ carries fixed anti-impact bumper pads that decelerate the piston at the stroke ends. If your cycle needs tunable air cushioning, the MACJ family is the cushioned counterpart; MA is the fixed-stroke version and MAD the double-rod one.
