About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-10S
The AirTAC SAIJ100X80-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 70-80 mm from the 80 mm nominal stroke. It delivers a robust 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This variant incorporates a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread for reliable pneumatic sealing. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning without adding external stops. It utilizes the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2, while omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-10S Is Used
Product Changeover Tuning
Dial in the 70-80 mm travel window during format changes to accommodate varying product sizes without swapping the cylinder.
End-Stop Calibration
Use the rear mechanical stopper to precisely set the retracted end position during machine commissioning, avoiding external stop blocks.
Corrosive Heavy-Duty Positioning
Leverage the 3927 N push force and SUS304 stainless rod for high-force actuation in washdown or mildly corrosive industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-10S the Right Cylinder?
Choose this 100 mm bore when your application demands high thrust, stepping up from a 63 mm bore that provides 1559 N push at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring exact end-position tuning during product changeovers rather than relying on a fixed-stroke SAI cylinder. Because the stroke is 80 mm, side-loading is minimal, but always ensure the load is guided externally for optimal longevity.
If the application requires the load to be held mechanically without continuous live air pressure, note that the rear adjuster and air cushions function only as travel stops, not locks. For true load-holding, consider using an SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. To replace an ISO 15552 cylinder, match the 100 mm bore, 80 mm stroke, 10 mm adjustment, PT port, desired mounting, and the -S magnet for CMSE/DMSE sensors.
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 SAIJ100BX80-10S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm, providing a usable travel window of 70 to 80 mm. It functions as a travel stop and does not lock the load without live air pressure.
