About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-100
The AirTAC SAIJ100X700-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 600-700 mm from its 700 mm nominal stroke. Delivering 3927 N push force at 0.5 MPa, it handles heavy actuation with precision. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.
This configuration includes a SUS304 stainless steel rod for corrosion resistance and PT tapered port threads. The rear adjuster acts purely as a mechanical stop to dial in end positions during commissioning; it is not a lock and will not hold the load without live air. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-100 Is Used
Long-Stroke Press Feed
Dial in the 600-700 mm travel window to synchronize material indexing without replacing the actuator.
Product Changeover Diverter
Quickly adjust the rear stopper to accommodate different package sizes on a packaging line.
Heavy Assembly Station
Leverage 3927 N push force at 0.5 MPa to position heavy jigs with fine end-position tuning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-100 the Right Cylinder?
Choose this 100 mm bore when 80 mm falls short, as the 80 mm bore provides 2513 N push force at 0.5 MPa compared to this unit's 3927 N. The 100 mm adjustment window is ideal for product changeovers on long-stroke lines, allowing you to trim travel without swapping cylinders or adding external stops. If you need to hold a load mid-stroke without air pressure, the SAIJ adjuster cannot perform this function; you must use a SAIL pneumatic lock or an external rod lock.
Because the 700 mm stroke creates an unsupported length, the 25 mm rod diameter and M20x1.5 thread require external guiding to prevent excessive side loading. This model uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552.
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 SAIJ100BX700-100 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 100 mm, providing a usable travel window of 600-700 mm. It sets the end position but does not lock the load without live air.
