About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X350-50SH
Trim the extend stroke of the MAJ25X350-50SH anywhere between 300 and 350 mm: the external stop screw takes up the ordered 50 mm window to suit the jig in front of it. At 0.5 MPa the bore 25 piston develops 245.3 N pushing and 206.1 N pulling, with air acting on both faces.
Its stainless-steel round barrel, rolled tight against aluminium-alloy covers, and its 20 um hard-chromed carbon-steel rod hold up in splash zones that age painted bodies fast. The built-in magnet is part of the standard build, so DMSG or EMSG sensors attach without waiting on a custom piston. Budget about 147 N of usable push at 0.5 MPa rather than the full rating for consistent cycle life.

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 MAJ25X350-50SH Is Used
PCB test fixture pusher
Nudges boards into a pogo-pin nest using the 206.1 N retract force, with the stroke trimmed to 300 mm for shallow fixtures.
Gate interlock actuator
Drives a machine-guard slide latch; the standard magnet plus an EMSG switch confirms the locked position back to the PLC.
Welding jig clamp
Holds bracket workpieces during spot welding; 343.4 N at 0.7 MPa is ample for light fixture clamping duties.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X350-50SH the Right Cylinder?
Compare both directions before committing: bore 20 (157 N) fits gentle sorting arms, bore 32 (402.2 N) suits fixture clamping - the 25 mm lands between at 245.3 N. The stop screw is an extend-side mechanical stop, so a suspended load will still sink if pressure is lost; keep external support where holding matters. Mount FA flange or LB foot and add I / Y rod knuckles as needed. The H suffix on this model denotes a build option - confirm its exact configuration from the current AirTAC datasheet before ordering. Because 350 mm runs past the 300 mm standard limit for bore 25, expect a special-order unit, and support the rod against side loads over that travel.
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 MAJ25X350-50SH FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa push reaches 343.4 N; theoretical maximum is 50 kgf at 1.0 MPa. Operating window 0.15-1.0 MPa (22-145 psi), temperature -20 to +70 C, rod speed 30-800 mm/s.
An external stop screw trims the extend stroke anywhere within the ordered 50 mm window (300-350 mm). It is a mechanical end stop for setup, not a mid-stroke lock or load brake - on air loss the piston can still drift, so support held loads separately.
