About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-10S
The AirTAC SAIJ100X750-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the retract end-position during commissioning. It provides a usable travel window of 740 to 750 mm, letting you dial back the nominal stroke by up to 10 mm without installing external stops. Delivering a robust 5497 N of push force at 0.7 MPa, it handles heavy loads with ease.
This model features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides, and it supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock to hold loads without live air.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-10S Is Used
Precision Press Tuning
Dial in the exact 740-750 mm end-stop during machine commissioning to ensure precise pressing depth without swapping out the entire actuator.
Product Changeover Stops
Quickly adjust the retract position by up to 10 mm to accommodate varying package sizes on a packaging line, minimizing downtime between production runs.
Heavy Load Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets or industrial components while fine-tuning the final resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-10S the Right Cylinder?
Choose this 100 mm bore cylinder when your application requires higher thrust than a 80 mm bore (which provides 3518 N at 0.7 MPa), but you want to avoid the size and air consumption of a 125 mm bore. The adjustable stroke is ideal for machine setups requiring variable end-stops or precise product changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot match. When replacing an ISO 15552 cylinder, verify the 100 mm bore, 750 mm stroke, 10 mm adjustment, PT tapered port, and the -S magnet.
Because this unit features a 750 mm stroke, the 25 mm rod diameter and M20x1.5 rod thread provide rigidity, but an external guide is highly recommended to prevent excessive side-loading on the long unsupported travel. For applications that require true position holding without continuous live air pressure, this cylinder is insufficient; you should select an AirTAC SAIL or BSAI series 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 SAIJ100BX750-10S FAQ
At an operating pressure of 0.7 MPa, this 100 mm bore cylinder provides a push force of 5497 N and a pull force of 3681 N. It can deliver a maximum push force of 7068 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a usable travel window of 740 to 750 mm. This mechanism acts as a travel stop to fine-tune the end position and deceleration, but it does not lock or hold the load without live air pressure.
