About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX450-10S
The AirTAC SAIJ100X450-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 440-450 mm, allowing you to dial back the nominal 450 mm stroke by up to 10 mm. This fine-tuning capability is ideal for setting precise retract end positions during commissioning without swapping out the entire unit.
The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic switches. It supports speeds of 30-800 mm/s and uses a PT tapered G1/2 port.

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 SAIJ100BX450-10S Is Used
Machine Setup Changeover
Fine-tune the 440-450 mm retract position during product line changeovers to accommodate varying part widths without re-engineering the fixture.
Variable End-Stop Tuning
Dial in the exact end-of-stroke position during machine commissioning, using the rear screw to absorb mechanical tolerance rather than adding external shims.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX450-10S the Right Cylinder?
The 10 mm adjustable window lets you trim the retract end-stop on the fly, which is far more efficient than machining external stop blocks or buying a fixed-stroke SAI cylinder for every product variation. Because the stroke is 450 mm, an external guide is recommended to manage side-load and prevent rod deflection.
For load-holding without live air pressure, note that the rear adjuster is strictly a travel stop, not a lock. You would need an SAIL pneumatic lock, a BSAI clamp-lock, or an external pilot-operated check valve. This SAIJ variant uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ100BX450-10S FAQ
At the maximum operating pressure of 0.9 MPa, the push force reaches 7068N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 450 mm down to 440 mm. It sets the travel end and relies on the air cushion for deceleration, but it does not lock or hold the load without live air pressure.
