About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X65-50S
Wide trim range defines this version: the external stop screw lets you set the effective extend stroke anywhere from 15 mm to the full 65 mm. Underlying that adjustability is a proven build - riveted stainless barrel, aluminium covers, 10 mm hard-chrome rod - producing 245.3 N of push and 206.1 N of pull at 0.5 MPa.
For sizing, count on roughly 147 N of practical force at 0.5 MPa (60 percent of rated push); that presses bearings into housings or clamps thin sheet without a booster. Fixed bumper pads decelerate the piston at stroke end, while mounting flexibility comes from FA flange and LB foot options plus I and Y rod knuckles. Operating window: 0.15-1.0 MPa (22-145 psi), -20 to +70 C.

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 MAJ25X65-50S Is Used
Crimping terminals on a wire harness line
Closes a small crimp die with 245 N at 0.5 MPa; the 50 mm window lets one cylinder serve multiple terminal heights.
Pallet-corner kickers in a warehouse
Nudges pallet corners square before stretch wrapping, adjusting stroke per pallet profile on site.
Gating on an egg-tray filling machine
Stops egg trays under the filler nozzle; an EMSG sensor on the built-in magnet verifies each index.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X65-50S the Right Cylinder?
Between the bore-20 sibling (157.0 N push at 0.5 MPa) and the bore-32 (402.2 N), this 25 mm actuator sits in the middle at 245.3 N. A 50 mm trim window is the largest offered on a 65 mm body, effectively turning one part number into several stroke lengths from 15 mm up. FA flange, LB foot and the I / Y knuckles cover most fixturing; rod thread is M10x1.25 male. The adjuster is a hard stop for position setting, never a load-holding device on pressure loss.
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 MAJ25X65-50S FAQ
Yes: 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; up to 50 kgf theoretical at 1.0 MPa. Stroke is nominally 65 mm and the stop screw trims the extend side by as much as 50 mm.
The riveted stainless barrel and 20 um hard-chrome carbon-steel rod shrug off mild corrosion and washdown better than painted minis, while the grease-storing two-way piston seal keeps friction low over millions of cycles. It is a compact round body, not a tie-rod or profile design.
