About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X45-10S
Short stroke, tight trim: the MAJ25X45-10S gives you a 45 mm double-acting cylinder whose extend stroke is adjustable down by up to 10 mm with the external stop screw. At 0.5 MPa the bore 25 piston develops 245.3 N on extend and 206.1 N on retract; at 0.7 MPa push climbs to 343.4 N. Plan continuous duty around 147 N and the unit will not run hot or stall mid-cycle.
Construction is AirTAC's riveted MA round body - stainless-steel barrel, hard-chrome carbon-steel rod, aluminium-alloy covers - so light corrosion and wash-hose splash are non-events compared with painted minis. A fixed anti-impact pad cushions the stroke ends (deceleration only, not an adjustable cushion), and because the magnet is built in as standard, CMSG / DMSG / EMSG switches attach straight out of the box. Porting is a 1/8" thread and the rod thread is M10x1.25.

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 MAJ25X45-10S Is Used
Carton flap tuck
Folds the final flap on a 45 mm carton-closing head; the 10 mm stop adjustment compensates for board thickness changes between batches.
Bench clamping fixture
Clamps aluminium blanks for deburring at up to 343.4 N with 0.7 MPa air, releasing the moment the pedal valve exhausts.
Part-present check nest
Confirms a workpiece seated in a fixture nest before the robot weld cycle starts, with a DMSG switch reading the built-in magnet.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X45-10S the Right Cylinder?
This model fills the gap where an MAJ20 (157.0 N push at 0.5 MPa) is too weak and an MAJ32 (402.2 N) is overkill. The 10 mm adjuster trims the extend end position only; it is not a mid-stroke brake, so anything that must stay parked under load needs its own clamp or mechanical stop. Mounting is FA flange or LB foot, with I and Y knuckles on the rod, and the standard magnet keeps position feedback to a single CMSG order. At 45 mm there is little leverage for rod bending, but still keep the thrust axial.
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 MAJ25X45-10S FAQ
Bore 25 mm, 45 mm stroke with a 10 mm adjustable trim window. Forces: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, and 50 kgf theoretical max at 1.0 MPa. Ports are 1/8"; supply 0.15-1.0 MPa (22-145 psi).
No. The pad is fixed and simply softens the piston's arrival at each stroke end; it cannot be tuned the way an adjustable cushion can. If you need tunable deceleration, look at the MACJ family, which pairs the stroke adjuster with air cushioning.
