About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X75-50S
Half of this cylinder's 75 mm travel is trimmable: with a 50 mm window, the MAJ25X75-50S covers a broad family of stroke settings on one part number. The 25 mm double-acting bore delivers 245.3 N at 0.5 MPa (343.4 N at 0.7 MPa), which supports a vertical lift of roughly 13 kg with a 2:1 margin - useful when matching real part weights on lift applications.
The stainless-steel round barrel shrugs off splash, humidity and light washdown that quickly ruin painted mini cylinders, while the hard-chrome plated 10 mm rod keeps seal wear low over millions of cycles. Fixed anti-impact bumper pads cushion both stroke ends, and because the magnet is a standard fitting, CMSG or DMSG switches simply clamp on the tube. Speed range 30-800 mm/s, air supply 0.15-1.0 MPa (22-145 psi).

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 MAJ25X75-50S Is Used
Conveyor sorting pusher
Kicks small parcels or blisters onto a reject lane; the wide 50 mm trim lets one cylinder serve multiple lane widths, with a DMSG switch verifying the eject completed.
Gluing head lift on a woodworking line
Raises and lowers a glue nozzle onto panel edges; 245.3 N at 0.5 MPa holds the head firmly against the work and the stainless barrel handles glue-booth humidity.
Pallet-nesting stop on a transfer cart
An indexing stop that catches pallet cages on a transfer rail; the bumper pad absorbs cart impact and the trim screw sets the stop position without shimming.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X75-50S the Right Cylinder?
Compare before you buy: 20 mm bore gives 157 N at 0.5 MPa, this 25 mm gives 245.3 N, and 40 mm reaches 628.3 N - choose by the load plus a 30-50 percent margin. Position feedback via the built-in magnet costs nothing extra. Mounting choices: FA flange for face mounting, LB foot for base mounting, I or Y knuckle on the rod. Keep in mind the 50 mm stop screw is an extend-side end stop, not a mid-stroke positioner; on air failure the rod may settle. Rod thread is M10x1.25 and the air port is 1/8 inch.
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 MAJ25X75-50S FAQ
Bore 25 mm, stroke 75 mm with a 50 mm adjustable extend window. Double-acting: push 245.3 N, pull 206.1 N at 0.5 MPa; push 343.4 N, pull 288.5 N at 0.7 MPa; up to 50 kgf theoretical at 1.0 MPa. Air 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, 1/8 inch port, M10x1.25 rod thread.
Better than most minis in its class. The barrel is stainless steel with rolled aluminium covers instead of a painted steel tube, and the piston rod is hard-chrome plated to about 20 um, so splash, condensation and periodic washdown cause far less trouble than on painted or bare-aluminium bodies. The fixed bumper pads are molded in, and the standard magnet keeps sensing simple even in these conditions.
