About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X25-30S
Setup tolerance is the selling point here: the MAJ25X25-30S is a double-acting mini cylinder whose extend stroke can be wound in by up to 30 mm with its external stop screw, so one actuator covers several part heights on the same fixture. The 25 mm bore delivers 245.3 N forward and 206.1 N back at 0.5 MPa, peaking at 343.4 N forward at 0.7 MPa.
Build quality matches the flexibility. A stainless round barrel is rolled onto aluminium covers around a hard-chrome 10 mm rod, so humidity and washdown cause little trouble. Fixed bumper pads soften stroke-end impact (deceleration only - this is not the cushioned MAC family). Feed it filtered air at 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, and count on about 12.5 kg of vertical lift capability once you keep a 2:1 margin.

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.

Vial stopper seating
Seating stoppers on sample vials in a lab filler, with 30 mm of stroke adjustment for vial sizes.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X25-30S the Right Cylinder?
If 245.3 N at 0.5 MPa feels tight for the job, step up to bore 32 (402.2 N) rather than running near the limit; if it is generous, bore 20 (157.0 N) may do the same work more cheaply. The stop screw is a mechanical extend end-stop only - on air loss the rod still drifts, so add a clamping element where position must hold. Mount via FA flange or LB foot, add an I or Y knuckle, and use the standard-fit magnet with CMSG / DMSG / EMSG switches for end-of-trim sensing.
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 MAJ25X25-30S FAQ
Extend stroke 25 mm adjustable by up to 30 mm via the stop screw; push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N at 0.7 MPa; 50 kgf theoretical maximum at 1.0 MPa. Port is 1/8", rod thread M10x1.25.
It is a fixed elastomer pad that absorbs the last of the travel to cut noise and wear. It cannot be tuned like the adjustable air cushion on the MAC family - for that function order MACJ instead.
