About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-100
The AirTAC SAIJ80X200-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 200 mm travel by up to 100 mm. This creates a highly flexible 100-200 mm usable window, perfect for fine-tuning end positions during commissioning without swapping out the entire actuator.
Unlike fixed-stroke alternatives, this model lets you set the exact retract stop mechanically via the rear screw, though it acts only as a travel stop and not a lock. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. It uses a PT G3/8 port and omits the FB, CA, CB, and CR mounting interfaces, supporting a streamlined set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX200-100 Is Used
Machine Changeover
Quickly dial in the 100-200 mm retract position during product size changes without replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the exact end-of-stroke location at commissioning using the rear adjuster, absorbing mechanical tolerances in the fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-100 the Right Cylinder?
The 100 mm adjustment range is particularly useful for product changeovers on a packaging line, allowing operators to reposition the retract end-stop mechanically without adding external stops or changing the cylinder. If your process demands holding the load without live air pressure, note that this cylinder's rear adjuster is strictly a stop; you would need to look at the SAIL or BSAI series for true pneumatic locking. For ISO 15552 interchangeability, match the 80 mm bore, 200 mm stroke, PT G3/8 port, and the desired mounting hardware.
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 SAIJ80 Adjustable Cylinder SAIJ80BX200-100 FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 513 kgf.
The rear adjuster screw lets you shorten the 200 mm nominal stroke by up to 100 mm, providing a usable travel window of 100-200 mm. It acts as a mechanical stop to set the end position and is not a lock.
