About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-10
The AirTAC SAIJ100X800-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 3927N of push force at 0.5 MPa and provides a usable travel window of 790-800mm, letting you dial back the nominal 800mm stroke by up to 10mm during commissioning.
This specific SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads (G1/2). The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the M20x1.5 rod thread handles high side-load stresses effectively.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-10 Is Used
Machine Changeover
Fine-tune the 790-800mm travel end-stop during product size transitions without swapping out the entire actuator.
Assembly Press
Leverage the 3927N push force and SUS304 rod for precise pressing operations requiring minor position adjustments.
Long-Stroke Diverting
Adjust the exact retraction point of an 800mm stroke diverter arm to accommodate varying package dimensions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-10 the Right Cylinder?
Choose this 100mm bore adjustable cylinder over a fixed SAI when you need precise end-position tuning at machine setup without adding external stops. If your application requires less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa. Because the stroke is 800mm, an external guide is strongly recommended to prevent rod binding under heavy lateral loads.
Remember that the rear adjuster acts only as a travel stop, not a locking device; a plain SAIJ cannot hold a load without live air pressure. For drop-out prevention, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. To match this ISO 15552 interchangeable footprint, specify the 100mm bore, 800mm stroke, PT port, and desired mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAIJ100BX800-10 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. The maximum force at 1.0 MPa is 801 kgf.
The rear adjuster screw lets you shorten the effective travel by up to 10mm, creating a 790-800mm usable window. It acts as a mechanical stop to fine-tune the end position without live air holding the load.
