About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X250-20S
A 20 mm adjustment window gives the MAJ32X250-20S on-site control over where its 250 mm extend stroke ends. Double-acting on both faces, it pushes with 402.2 N and pulls with 345.6 N at 0.5 MPa, and it runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air.
Fixed anti-impact bumper pads soften each stroke end - they decelerate, but they are not adjustable air cushions like the MAC family offers. Thinking vertically, the bore is roughly a 41 kg force equivalent at 0.5 MPa, so with a 2:1 margin it lifts about 20 kg. FA flange or LB foot mounting bolts the riveted stainless body into compact machine frames.

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 MAJ32X250-20S Is Used
Small die lifting
Vertical lift of small dies and fixtures - the 32 mm bore equates to about 41 kg of force at 0.5 MPa, so parts near 20 kg rise with a 2:1 margin.
Bushing press-fit
Presses bushings into housings on a light arbor press; 563.0 N at 0.7 MPa handles small interference fits without a full-size press.
Tray lid press
Snaps lids onto filled food trays at the end of a filling line; the stainless round body wipes clean in damp washdown zones.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X250-20S the Right Cylinder?
Compare before you buy: the 25 mm bore (245.3 N push at 0.5 MPa) suits lighter clamps, while the 40 mm bore (628.3 N) is the next rung up for heavier presses. On a 250 mm travel, avoid letting the load cantilever off the 12 mm rod; an external guide keeps side force out of the barrel.
Be clear about what the adjuster does: it is a mechanical stop for the extend end, not a brake - with air lost the piston still moves. FA flange and LB foot mounts cover most frames, rod knuckles come as I or Y, and the standard magnet accepts CMSG / DMSG / EMSG switches without ordering options.
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 MAJ32X250-20S FAQ
Measured output: 402.2 N push and 345.6 N pull at 0.5 MPa, climbing to 563.0 N push and 483.8 N pull at 0.7 MPa. The theoretical ceiling at 1.0 MPa is 82.0 kgf. Rod diameter is 12 mm, the port is 1/8", and the 250 mm stroke sits inside the 500 mm standard limit for this bore.
No - the MAJ carries fixed anti-impact bumper pads that decelerate the piston at each stroke end. They soften impact but are not adjustable air cushions; if your machine needs adjustable cushioning, that is the MAC family's territory.
