About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X450-100S
Long travel on a slim budget: this made-to-order MAJ25X450-100S reaches 450 mm from a 25 mm bore, with an external stop screw setting the extend end anywhere inside a 100 mm window when one machine handles parts of several depths. The stainless round barrel and hard-chrome plated 10 mm rod keep the whole unit slender, and the riveted body tucks into frames a wider profile cylinder cannot.
Force stays in the light class over that reach: 245.3 N forward and 206.1 N back at 0.5 MPa, 343.4 N and 288.5 N at 0.7 MPa, 50 kgf theoretical peak. Plan continuous work around about 147 N at 0.5 MPa rather than the full rating. Bumper pads are fixed, speed runs 30-800 mm/s, and pressure spans 0.15-1.0 MPa (22-145 psi); the standard magnet is ready for CMSG / DMSG / EMSG switches.

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 MAJ25X450-100S Is Used
Wide-belt diverter
The 450 mm reach pushes cartons fully across a wide conveyor lane; 245.3 N push at 0.5 MPa is ample for light cases guided on rails.
Guard door actuator
Opens a sliding machine guard the full 450 mm; a DMSG switch on the standard magnet signals the door-open position to the controller.
Deep tray extractor
Pulls a storage tray out of a dense racking cell; at 0.7 MPa the 343.4 N push handles tray plus loaded drawers while external rails carry the weight.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X450-100S the Right Cylinder?
The 450 mm stroke overruns the 300 mm standard limit of the 25 mm series, so treat it as a made-to-order item and confirm delivery before design freeze. With 157 N at 20 mm and 402.2 N at 32 mm (0.5 MPa) as reference points, this bore suits light loads over long reach - but guide the load on external rails and consider an FA flange with an LB foot so side forces never reach the rod. The stop screw fixes the extend end only and will not lock the load when air fails; the built-in magnet plus CMSG / DMSG / EMSG switches provide position signals along the 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 MAJ25X450-100S FAQ
Force at 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; 50 kgf theoretical maximum at 1.0 MPa. The 450 mm stroke is made to order - the standard 25 mm series stops at 300 mm - and the extend end is settable anywhere within the 100 mm window via the external stop screw.
A slender stainless tube with a hard-chrome rod stays compact and corrosion-resistant across 450 mm of travel, where a wider profile body or painted steel would be bulkier or rust-prone. End pads are fixed bumpers, not adjustable cushions; the MACJ adds adjustable cushions and the MAD adds a second rod if the job needs them.
