About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X125-100S
With a 100 mm trim range the MAJ25X125-100S behaves like a small kit of fixed cylinders: one unit covers extend strokes from 125 mm down to 25 mm, reset in seconds at the stop screw. Output stays at 245 N push and 206 N pull on 0.5 MPa, 343 N push at 0.7 MPa, with a 50 kgf theoretical top figure. The stainless round barrel and hard-chrome plated rod (20 um chrome layer) laugh at splash zones, and the riveted body keeps a compact footprint.
Bumper pads at each end are fixed - they cushion end of travel but are not tunable air cushions; the MACJ family handles that job. Do not rely on the stop screw to hold a load mid-stroke: it defines an extend limit only, and the rod drifts if pressure is lost. The magnet comes standard, so CMSG, DMSG and EMSG sensors drop straight onto the barrel.

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 MAJ25X125-100S Is Used
Tote indexing pusher
Indexes picking totes on a warehouse conveyor; one cylinder serves tote depths across the 25-125 mm span.
Scrap compactor door
Closes small scrap-compactor doors at a machining cell, taking 245 N of push repeatedly through the full 125 mm travel.
Test rig loading arm
Applies a controlled press force to connector test fixtures; the 100 mm window retunes stroke per fixture type.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X125-100S the Right Cylinder?
Sizing check: the MAJ20 manages 157 N at 0.5 MPa and the MAJ32 offers 402 N - if your part weighs up to about 12 kg, this bore already halves its 25 kgf vertical capability for a 2:1 lift margin, so stay here rather than upsizing. The stop screw trims only the extend direction and never holds a load when air fails; fit a separate brake for safety holds. Mount with an FA flange or LB feet, add I or Y knuckles for pivoting rods, and keep external guides on the 125 mm stroke to protect the rod from side load.
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 MAJ25X125-100S FAQ
Push 245 N, pull 206 N at 0.5 MPa; push 343 N, pull 289 N at 0.7 MPa; 50 kgf theoretical max at 1.0 MPa. Pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, 1/8 port, M10x1.25 rod thread, and the extend stroke adjusts within a 100 mm window from the 125 mm ordered stroke.
Yes - the rolled stainless barrel, aluminium covers and 20 um hard-chrome rod resist washdown splashes, outdoor condensation and cutting-fluid mist far better than painted mini cylinders. Add the fixed anti-impact bumpers, FA/LB mounting choices and the standard magnet for CMSG, DMSG and EMSG switches, and one unit covers many duties.
