About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-20S
An external stop screw on the AirTAC MAJ25X160-20S lets you dial the extend stroke shorter anywhere inside the ordered 20 mm band - the retract stroke stays full and the action stays double-acting. This 25 mm bore delivers 245.3 N of push and 206.1 N of pull at 0.5 MPa, or 343.4 N at 0.7 MPa.
Fixed anti-impact pads ease the piston into each end of travel; they decelerate only and are not an adjustable air cushion, which is the MAC family's job. Plan work around 147 N at 0.5 MPa - about 60 percent of the 245.3 N rating - and the stroke keeps headroom for plant pressure dips. Aluminium covers are riveted to the stainless barrel, so the round body stays compact in tight fixture pockets.

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 MAJ25X160-20S Is Used
Carton Flap Tuck on a Case Packer
With about 147 N of practical output at 0.5 MPa, the 25 mm bore tucks corrugated flaps closed without crushing; the 20 mm trim window absorbs gauge and glue variations.
Gate Indexing on a Small CNC Bar Feeder
The 343.4 N push at 0.7 MPa snaps a sorting gate between bar channels, and the fixed bumpers keep the gate from slamming at each index.
Divert Arm on a Sorter Lane
A warehouse sorter lane uses the arm to push parcels sideways; the riveted stainless body stands up to dusty air, and the magnet feeds a DMSG switch for divert confirmation.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-20S the Right Cylinder?
Bore neighbors: the 20 mm MAJ at 157.0 N [email protected] MPa covers lighter picks, while the 32 mm bore at 402.2 N handles heavier clamps - the 25 mm class sits between them. Fit the FA flange or LB foot; I and Y knuckles are the rod accessory choices, with no SDB variant offered on this adjustable type.
Because the external stop is a position setter, not a brake, anything that must stay put under air loss needs its own mechanical clamp. With 160 mm of rod exposure, keep the driven slide supported so side loads stay minimal.
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 MAJ25X160-20S FAQ
Figures for the 25 mm bore: 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, and a 50 kgf theoretical maximum at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi) with speeds from 30 to 800 mm/s.
Fixed anti-impact bumper pads sit at both ends of travel to soften piston arrival; they decelerate the piston but are not adjustable air cushions - for tunable cushioning, look at the MACJ family instead.
