About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-75
The AirTAC SAIJ200X280-75 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, pushing 15708N and pulling 15080N at 0.5 MPa, making it suited for heavy-duty positioning. By turning the external stopper screw, you can trim the nominal 280mm stroke back by up to 75mm, creating a precise 205-280mm usable travel window without swapping out the unit.
This 200mm bore actuator features a robust 40mm carbon steel rod with an M36x2 thread, paired with 50mm variable air cushions at both ends to manage high kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches if a magnet is added later. Mounting is limited to the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-75 Is Used
Heavy Mold Positioning
Dial in the exact 205-280mm retract distance when seating large industrial molds, ensuring perfect alignment without re-engineering fixed stop blocks.
Pallet Changeover Systems
Adapt a heavy-duty pallet handling line to different package sizes on the fly by adjusting the rear stopper screw up to 75mm during product changeovers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-75 the Right Cylinder?
Select this 200mm bore actuator when your machinery requires extreme force that smaller bores cannot provide, such as shifting heavy pallets or large molds. The adjustable 205-280mm travel window is ideal for production lines running mixed product sizes, allowing you to fine-tune the retract end position during changeovers rather than machining external hard stops.
Because the 280mm stroke is substantial, the heavy tooling mounted on the 40mm rod will generate significant side loads; always utilize an external guide rail to prevent binding and premature seal wear. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL pneumatic lock or a BSAI clamp-lock cylinder. To match this ISO 15552 footprint exactly, specify the 200mm bore, 280mm stroke, 75mm adjustment, PT tapered port thread, and your required mounting kit.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-75 FAQ
At the maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 280mm down to a minimum of 205mm. This creates a 205-280mm usable window for fine-tuning the retract end position during setup without replacing the cylinder.
