About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X30-30S
Short strokes in cramped fixtures are the natural home of the MAJ25X30-30S: a 25 mm bore double-acting mini cylinder that pushes 245.3 N and pulls 206.1 N at 0.5 MPa, with the extend stroke set by a stop screw anywhere inside the ordered 30 mm window.
Its riveted round body pairs a stainless tube with a hard-chrome carbon-steel rod, so splashing coolant and outdoor humidity cause little trouble compared with painted-steel minis. Fixed anti-impact bumpers tame the stroke ends (they decelerate only; adjustable cushioning belongs to the MACJ line). In practical terms the rod lifts about 12 kg vertically once a 2:1 margin is applied, and the standard-fit magnet works with CMSG, DMSG and EMSG switches out of the box.

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 MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X30-30S Is Used
Lift pin under a rotary dial table
Raises indexing pins weighing under 12 kg; the trimmable stop leaves the pin exactly flush with the dial surface every cycle.
Carton flap tucker on a small wrapper
Folds the final flap of boutique gift cartons; the coolant-tolerant stainless barrel suits zones near washdown.
Sample vial pusher in a lab indexer
Feeds vials one at a time into an analyzer; speed tuned between 30 and 800 mm/s so no liquid spills in transit.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X30-30S the Right Cylinder?
One bore down, a 20 mm MAJ gives 157 N at 0.5 MPa; one bore up, 32 mm gives 402 N - pick by the load, not by price. Keep in mind the adjuster stops the extend stroke mechanically; it will not arrest drift when air pressure drops, so support the load separately if that matters.
FA flange and LB foot cover the base mounting, while I and Y knuckles suit swinging loads. Pressure range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, and the 1/8" port can be swapped to G or NPT when ordering.
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 MAJ25X30-30S FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; 50 kgf theoretical peak at 1.0 MPa. Rod is 10 mm with an M10x1.25 male thread, port 1/8", bore 25 mm, stroke speed 30-800 mm/s.
The fixed pad at each stroke end simply decelerates the piston to soften the hit; there is no needle valve and no way to tune it. If your cycle needs adjustable air cushioning at the ends, the MACJ cylinder is the related type to specify instead.
