About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-40S
The AirTAC SAIJ200X275-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the end position without adding external stops. The integrated -40 mm adjustment mechanism creates a usable travel window between 235 and 275 mm.
This variant includes a magnet for position sensing and uses a robust carbon steel rod with an M36x2 thread. Because the 275 mm stroke is well below the 1500 mm maximum standard stroke for this bore, the cylinder maintains a highly rigid footprint. The extruded aluminum barrel features sensor grooves on both sides, allowing you to mount CMSE reed or DMSE solid-state switches directly to the body.

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 SAIJ200X275-40S Is Used
Heavy Press Tuning
Dial in the exact 235-275 mm travel window during heavy press commissioning to ensure precise end-positioning without swapping out the entire cylinder.
Product Size Changeovers
Quickly adapt the retract stop on a conveyor sorting line to handle varying package sizes by adjusting the rear screw on the fly.
Machine Setup Calibration
Use the 40 mm adjustment range to fine-tune the end-of-stroke position during initial machine assembly, compensating for mechanical tolerances.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-40S the Right Cylinder?
The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops to accommodate product changeovers or fine-tune a machine setup during commissioning. Remember that the rear adjuster functions strictly as a travel stop, not a lock—the cylinder will not hold its load without live air pressure. For true fail-safe load holding, consider using an external rod lock, a pilot-operated check valve, or the AirTAC SAIL/BSAI locking cylinder series.
When replacing an ISO 15552 cylinder, match these exact parameters: 200 mm bore, 275 mm nominal stroke, 40 mm adjustment range, PT (tapered) G3/4 port, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR variants. Although this 275 mm stroke is relatively short for the bore, the heavy 40 mm rod and M36x2 thread handle high side loads well, though any long unsupported travel still requires an external guide.
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 SAIJ200X275-40S FAQ
It can deliver a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 275 mm down to 235 mm, creating a 235-275 mm usable window. It only sets the travel end and does not lock the load without live air pressure.
