About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX70-10
The AirTAC SAIJ100X70-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position without adding external stops. It provides a usable travel window of 60 to 70 mm, letting you dial in the exact retract distance during machine commissioning. Delivering a robust push force of 5497 N at 0.7 MPa, it is built to handle demanding industrial loads.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a speed range of 30-800 mm/s and uses self-centering variable air cushions at both ends to decelerate the payload smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX70-10 Is Used
Machine Changeover
Dial in the 60-70 mm stroke window during product size changes to set exact end positions without repositioning the cylinder.
End-Position Tuning
Fine-tune the retract stop during commissioning to compensate for mechanical tolerance variations in the fixture.
High-Force Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets while maintaining a compact 70 mm nominal stroke.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX70-10 the Right Cylinder?
Choose this 100 mm bore actuator when your application requires high thrust—up to 5497 N at 0.7 MPa—and precise mechanical end-stop tuning. If you need less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, while a 125 mm bore provides 8590 N for heavier payloads. The integrated 10 mm rear adjuster is ideal for product changeovers, allowing you to shorten the stroke on the fly without swapping the cylinder or bolting on external stopper blocks.
Because this is a double-acting cylinder, the rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold the position without live air pressure. For load-holding requirements without continuous air, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve. This SAIJ model is dimensionally interchangeable per ISO 15552 and is available with Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting brackets.

- ✓ 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 SAIJ100BX70-10 FAQ
At an operating pressure of 0.7 MPa, this 100 mm bore cylinder generates a push force of 5497 N and a pull force of 3681 N. At the maximum pressure of 1.0 MPa, it provides a push force of 7068 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 70 mm down to as little as 60 mm. This creates a 60-70 mm usable window for fine-tuning the end position at commissioning without swapping the cylinder.
