About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-100S
A full 100 mm of on-site adjustment is the headline: the MAJ25X160-100S lets one cylinder serve several product sizes by winding the stop screw across its extend stroke. Under that flexibility sits a 25 mm bore producing 245.3 N at 0.5 MPa - about 147 N of dependable working force, or roughly 12 kg of vertical lift with a 2:1 margin. It runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air.
Fixed anti-impact pads take the sting out of both stroke ends (deceleration only - for tunable cushioning step up to the MACJ). The stainless barrel, hard-chrome rod and riveted aluminium covers suit damp plants and outdoor fixtures, and the built-in magnet makes CMSG, DMSG or EMSG switching a clip-on rather than an option.

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 MAJ25X160-100S Is Used
Sorter stop gate
Set a different stop point for each carton size across the 100 mm window - no cylinder swaps when the SKU mix changes on the sorter.
Die part ejector
Ejects finished parts from a small die or fixture; the stop sets ejection depth so thin parts are not flipped off the table.
Position-verified clamp
A CMSG or DMSG switch on the standard magnet confirms clamp closure on a leak-test fixture where the stainless body meets coolant mist.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-100S the Right Cylinder?
Force-wise, this bore sits between the MAJ20 (157 N push at 0.5 MPa) and the MAJ32 (402.2 N); at 245.3 N it handles medium loads with headroom. The 100 mm trim range is the widest the MAJ adjustable series offers in this bore, so a single cylinder can serve multiple stop positions across a family of parts. Note the stop governs the extend stroke only - it is not a position lock, and loads can move if the air supply fails.
Mount with an FA flange or LB foot; I and Y rod knuckles join the tooling (no SDB variant on adjustable models). At 150 mm of stroke, keep external guidance on the load so the 10 mm rod carries pure axial force. The standard magnet pairs with CMSG, DMSG and EMSG switches for end-of-travel confirmation.
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 MAJ25X160-100S FAQ
At 0.5 MPa expect 245.3 N extend and 206.1 N retract; at 0.7 MPa, 343.4 N extend and 288.5 N retract. Maximum theoretical force at 1.0 MPa is 50 kgf. The 25 mm bore takes 1/8" ports and uses an M10x1.25 male rod thread on a 10 mm rod.
Choose FA flange or LB foot mounting, with I or Y rod knuckles on the rod end; SDB is not offered on the adjustable series. Impact at each end of travel is softened by fixed anti-impact bumper pads - they decelerate the piston but are not adjustable air cushions.
