About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-100
The AirTAC SAIJ80X700-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 100 mm. This creates a usable 600-700 mm adjustable window, providing exact end-position tuning during commissioning without adding external stops. It delivers a robust 4523 N push force at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch placement. The rear adjuster functions strictly as a travel stop to fine-tune the retract position, so live air pressure is required to maintain the load.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-100 Is Used
Machine Setup Changeover
Dial in the exact 600 to 700 mm retract position during product family changeovers without swapping out the entire cylinder assembly.
Variable End-Stop Positioning
Fine-tune the stopping point of heavy pallets on a conveyor line by adjusting the rear screw up to 100 mm on the fly.
Heavy-Duty Assembly Press
Leverage the 4523 N push force to seat large components, using the adjustable travel window to set precise pressing depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-100 the Right Cylinder?
Choose this 80 mm bore when your application requires substantial force, stepping up from a 63 mm bore that provides 2805 N at 0.9 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, whereas a fixed SAI cylinder lacks this built-in tuning flexibility. Because the nominal 700 mm stroke is long, an external guide is recommended to handle side loads and prevent rod binding.
To replace an ISO 15552 cylinder, match the 80 mm bore, 700 mm stroke, 100 mm adjustment range, PT port thread, and SUS304 rod material. Note that SAIJ uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. This model does not include a magnet; adding an -S option enables CMSE reed and DMSE electronic sensors.

- ✓ 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 SAIJ80BX700-100 FAQ
At a 0.9 MPa operating pressure, the 80 mm bore generates 4523 N of push force and 4068 N of pull force, with a maximum thrust of 513 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that shortens the 700 mm nominal stroke, providing a 600 to 700 mm travel window for fine-tuning the retract end position at commissioning.
