About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X500-10S
The MAJ25X500-10S pairs a 25 mm stainless round barrel with a 10 mm hard-chrome rod on a 500 mm base stroke, and an external stop screw trims the extend stroke by up to 10 mm after installation. Push force reaches 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa, with 206.1 N of pull at 0.5 MPa.
Because the riveted stainless body shrugs off mild corrosion and washdown, it fits damp, food or outdoor spots where painted minis fail. Plan on roughly 147 N of real work at 0.5 MPa rather than the full rating, which is about 12 kg of vertical lift with a 2:1 margin. Fixed bumper pads soften stroke end, and the built-in magnet accepts CMSG, DMSG or EMSG switches with no special-order piston.

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 MAJ25X500-10S Is Used
Carton reject pusher
Sweeps misprinted cartons off a packaging conveyor at the 500 mm mark, with the 10 mm trim absorbing minor lane changes.
Washdown guard door
Slides a stainless guard door on a dairy filler, where the rolled round body stands up to daily hose-down.
Fixture eject
Ejects finished housings clear of a CNC fixture after the cut, pushing parts in the 12 kg vertical-lift class.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X500-10S the Right Cylinder?
At 500 mm this stroke exceeds the 300 mm standard ceiling for a 25 mm bore, so it ships as a made-to-order build. If your load stays under 90 N, the 20 mm bore (157 N push at 0.5 MPa) saves air; over 230 N, step up to the 32 mm bore (402.2 N). The trim stop is a mechanical extend limit only - the rod can still drift if air is lost, so clamp the load separately. FA flange or LB foot plus I/Y rod knuckles cover the fixturing; on a 500 mm stroke, guide the rod externally to keep side loads off the barrel.
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 MAJ25X500-10S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push rises to 343.4 N (288.5 N pull). Theoretical maximum at 1.0 MPa is 50 kgf. Supply is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, speed 30-800 mm/s, 1/8" ports and an M10x1.25 male rod thread.
Yes on both counts. The rolled stainless tube and 20 um hard-chrome plated rod resist moisture and mild chemicals better than painted mini cylinders, and every MAJ ships with a built-in magnet that triggers CMSG, DMSG or EMSG switches - no special-order piston required.
