About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-30S
This 25 mm bore MAJ pushes 245.3 N at 0.5 MPa and pulls 206.1 N - plan on roughly 147 N of real work if you want headroom. Its 30 mm adjust window lets the stop screw trim the 175 mm extend stroke in place, from outside the body.
AirTAC packs the aluminium covers and stainless block onto the tube by rolling, so the round body stays compact and sealed. Run it on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s; the standard magnet makes position sensing with CMSG / DMSG / EMSG a bolt-on job.

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 MAJ25X175-30S Is Used
Diverter blade actuation
Swings a light diverter blade across a parcel sorter lane; 206.1 N pull at 0.5 MPa handles the return spring.
Glue bead end-stop
Sets the travel limit on a glue-bead applicator carriage, re-trimmed per part revision.
Drawer latch sequence
Locks pick-module drawers before a lift stage moves, confirmed by a DMSG switch on the standard magnet.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-30S the Right Cylinder?
Compare before ordering: a bore 25 push of 245.3 N at 0.5 MPa covers most light clamping; go to bore 32 (402.2 N) for heavier jigs or down to bore 20 (157.0 N) to save air. The 30 mm window fits product-size changes on a single fixture. At 175 mm this is a long stroke for a 10 mm rod - guide side loads externally so the rod sees thrust only.
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 MAJ25X175-30S FAQ
Bore 25 at 0.5 MPa: 245.3 N push, 206.1 N pull. At 0.7 MPa: 343.4 N push, 288.5 N pull. Maximum theoretical output at 1.0 MPa is about 50 kgf. Air must be filtered to 40 um; speed range is 30-800 mm/s.
No - every MAJ ships with the magnet built in as standard, so CMSG, DMSG or EMSG switches mount on the barrel without a special-order piston. The 1/8" ports and M10x1.25 male rod thread come from the bore 25 row of the datasheet.
