About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-50S
With a 50 mm trim window - the widest offered on this series - the MAJ25X175-50S lets one cylinder serve several stroke settings on the same fixture. At 0.7 MPa it pushes 343.4 N; at 0.5 MPa, 245.3 N, which is around 12 kg of vertical lift when you keep a 2:1 margin.
Fixed anti-impact pads ease the piston at each end of travel (they decelerate only - the adjustable cushion version is the MACJ family). The two-way piston seal stores its own grease, keeping friction low across long duty cycles on 0.15-1.0 MPa (22-145 psi) air.

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 MAJ25X175-50S Is Used
Multi-SKU carton hold-down
Holds cartons of three different heights during case taping; the 50 mm window covers every SKU without swapping cylinders.
Sheet stack knock-down
Taps leaning sheet stacks square on a paper converting line, cycled anywhere in the 30-800 mm/s speed band.
End-of-arm present check
Confirms part seating on a pick cell via an EMSG switch, with the stop screw limiting probe reach per part.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-50S the Right Cylinder?
Bore choice at a glance: 20 mm gives 157.0 N, this 25 mm gives 245.3 N, and 32 mm gives 402.2 N, all at 0.5 MPa. Pick this one when loads land between roughly 100 and 150 N. The wide 50 mm window suits multi-product fixtures; keep the full 175 mm stroke for reach and trim down per SKU. Since the adjuster is just an end stop, external guidance still carries any side loads on a stroke this long.
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 MAJ25X175-50S FAQ
At 0.5 MPa: 245.3 N push, 206.1 N pull. At 0.7 MPa: 343.4 N push, 288.5 N pull. Theoretical peak at 1.0 MPa: about 50 kgf. Operate between 0.15-1.0 MPa (22-145 psi) and -20 to +70 C with 40 um filtered air.
FA flange and LB foot are the catalogue mounts, with I and Y rod knuckles for pivoting links; the adjustable version has no SDB or back-cover code. The built-in magnet (standard) drives CMSG / DMSG / EMSG switches, and fluid ports are 1/8" on bore 25.
