About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-100
The AirTAC SAIJ100X800-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 700-800 mm usable travel window. Equipped with a SUS304 stainless steel rod and PT tapered port threads, it delivers 7068 N of push force at 0.9 MPa. This bore size features a 25 mm rod and M20x1.5 rod thread, providing a robust interface for heavy loads.
The integrated rear stopper allows precise end-position tuning during commissioning without swapping the cylinder or adding external stops. It retains the standard extruded aluminum barrel with dual sensor grooves, though position detection requires adding a magnet separately. The adjuster and variable air cushions only decelerate the travel end; neither holds the load without live air.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-100 Is Used
Variable End-Stop Positioning
Fine-tune the retraction point within the 700-800 mm window during machine setup to accommodate different product lengths without mechanical rebuilds.
Heavy Load Transfer
Pushes heavy pallets or workpieces using 7068 N of force at 0.9 MPa, relying on the robust 25 mm SUS304 rod for durability in harsh environments.
Commissioning Calibration
Dial in the exact end-of-stroke position during initial line commissioning to prevent overtravel damage, using the 100 mm adjustment range.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-100 the Right Cylinder?
Choose this 100 mm bore when a 80 mm cylinder (4523 N push at 0.9 MPa) lacks thrust, but a 125 mm bore is excessive. An adjustable stroke is ideal for product changeovers, letting you dial back the 800 mm nominal travel by up to 100 mm on the fly instead of installing a fixed-stroke SAI cylinder. To match this ISO 15552 footprint, specify 100 mm bore, 800 mm stroke, PT ports, SUS304 rod, and no magnet.
Because the stroke is 800 mm, the long unsupported piston rod is susceptible to side loads; always use an external guide to prevent binding. For applications requiring the load to be held without continuous air pressure, this cylinder is insufficient—select a SAIL lock or BSAI clamp-lock cylinder instead.
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 SAIJ100BX800-100 FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068 N of push force and 5497 N of pull force. It reaches a maximum thrust of 801 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that shortens the 800 mm nominal stroke by up to 100 mm, creating a 700-800 mm usable travel window. It only sets the travel end and does not lock the load without live air pressure.
