About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X250-40S
The AirTAC SAIJ200X250-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables position sensing across the 30-500 mm/s speed range.
This adjustable model transforms the fixed 250 mm stroke into a 210-250 mm usable travel window, trimming up to 40 mm off the retract end. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. A 40 mm carbon steel rod with an M36x2 thread handles substantial side loads, while the PT tapered port ensures a rigid pneumatic connection.

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 SAIJ200X250-40S Is Used
Heavy Press Fine-Tuning
Dial in the exact 210-250 mm retract position during machine commissioning to accommodate varying material thicknesses without replacing the cylinder.
Product Line Changeover
Quickly adjust the end-stop up to 40 mm when switching the production line to a new pallet or product size, minimizing downtime.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X250-40S the Right Cylinder?
The 40 mm adjustment mechanism is ideal for product changeovers, letting you dial in the exact end-position without swapping hardware or adding external stops. Remember that the rear adjuster acts purely as a travel stop; it will not hold the load without live air pressure. For true load-holding, consider the SAIL or BSAI series.
As a dimensionally interchangeable ISO 15552 cylinder, this model matches standard SAI footprint specifications: 200 mm bore, 250 mm stroke, 40 mm adjustment, G3/4 PT port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Since the stroke is 250 mm, ensure adequate external guiding to prevent rod binding under heavy loads.

- ✓ 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 SAIJ200X250-40S FAQ
At 0.7 MPa, the push force increases to 21991N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 40 mm, creating a 210-250 mm usable travel window. It decelerates the travel end but does not lock the load without continuous air pressure.
