About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-75
The AirTAC SAIJ100X290-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, providing a usable travel window of 215 to 290 mm. It delivers robust thrust, pushing with 5497 N and pulling with 3681 N at 0.7 MPa, making it well-suited for heavy-duty positioning tasks.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE reed or DMSE electronic sensors if a magnet is added later.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100BX290-75 Is Used
Product Changeover
Dial in the 215 to 290 mm travel window during line changeovers to accommodate different product lengths without physically replacing the actuator.
End-Stop Tuning
Use the rear screw to precisely set the retract end-position during machine commissioning, avoiding the need for machined external stop blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-75 the Right Cylinder?
The 75 mm rear adjustment screw is ideal for product changeovers, letting you fine-tune the end position without swapping cylinders or adding external stops. Remember, the adjuster acts as a travel stop, not a lock; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 290 mm stroke, PT G1/2 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2, omitting FB/CA/CB/CR). Because the 290 mm stroke is relatively long, ensure you use an external guide to support the rod and prevent excessive side-loading.
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 SAIJ100 Adjustable Cylinder SAIJ100BX290-75 FAQ
At its maximum 1.0 MPa pressure, the push force reaches 7068 N.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the effective travel from the 290 mm nominal stroke down to 215 mm. This provides a 75 mm tuning window for commissioning without changing the cylinder's physical mounting.
