About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X300-100S
When the job needs real reach, the MAJ25X300-100S stretches the 25 mm MAJ platform to a 300 mm stroke - the longest standard length for this bore - while still trimming the extend stroke up to 100 mm via its external stop screw. At 0.5 MPa expect 245.3 N of push and 206.1 N of pull.
The riveted stainless tube and hard-chrome 10 mm rod keep corrosion at bay through wet or outdoor runs, something painted minis cannot promise. Because the magnet comes fitted as standard, CMSG, DMSG or EMSG switches mount anywhere along the barrel for end-of-stroke signals. For real work, budget about 147 N at 0.5 MPa, and the rod equates to roughly 12 kg of vertical lift once a 2:1 margin is applied.

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 MAJ25X300-100S Is Used
Cross-belt product pusher
Sweeps cartons off a 300 mm wide conveyor lane; the 100 mm window lets maintenance dial in the exact clear-off point without shimming.
Sliding guard door actuator
Draws a machine guard open across its full 300 mm travel; a DMSG switch on the standard magnet proves the door is open before cycle start.
Deep-magazine parts ejector
Pushes nested housings out of a 300 mm deep feeder magazine with 245.3 N of push, enough for a full stack of aluminum parts.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X300-100S the Right Cylinder?
Long strokes punish side loads: over 300 mm a 10 mm rod will bend or wear its seals if the load is not guided, so add external linear guides rather than letting the cylinder carry lateral force. If 300 mm is not enough, longer strokes are made to order.
Compared with the 20 mm bore (157 N at 0.5 MPa) and the 32 mm bore (402 N), this 25 mm bore is the middle choice at 245.3 N. Mount via FA flange or LB foot, use I or Y knuckles for pivoting loads, and remember the stop screw is an end stop, not a brake - on air loss the piston keeps drifting.
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 MAJ25X300-100S FAQ
300 mm is the maximum standard stroke for the 25 mm bore; anything beyond is made to order. Force stays constant along the travel: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push at 0.7 MPa, and a 50 kgf theoretical maximum at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi) with speed from 30 to 800 mm/s.
Anywhere along the stainless barrel. The piston magnet is standard equipment, so CMSG, DMSG and EMSG switches sense position without clamps or modifications; slide them to the exact trip point and lock them in place.
