About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-10S
The AirTAC SAIJ100X700-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 3927N of push force at 0.5 MPa and features a 10mm adjustment range, creating a precise 690-700mm usable travel window for fine-tuning the retract end position during commissioning.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston (-S) for position sensing. It uses PT tapered ports and retains the standard extruded aluminum barrel with sensor grooves on both sides, accepting the reduced SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-10S Is Used
Machine Setup Fine-Tuning
Dial in the exact 690-700mm retract position during initial machine commissioning without swapping cylinders or fabricating external stopper blocks.
Product Size Changeovers
Quickly adjust the end-of-stroke position by up to 10mm on packaging lines running slightly different product lengths.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for pushing and pulling heavy loads in washdown or mildly corrosive industrial settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-10S the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (providing 2513N push at 0.5 MPa) lacks thrust, but a 125mm bore is physically too large. The 10mm adjuster is ideal for dialing in exact end-stops during product changeovers without adding external stops. For load-holding without live air pressure, note that the rear adjuster acts only as a travel stop and not a lock; consider an AirTAC SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 100mm bore, 700mm stroke, PT port thread, and the desired mounting style. Because the stroke is 700mm, the 25mm 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.
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 SAIJ100BX700-10S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the nominal 700mm stroke by up to 10mm, providing a usable travel window of 690-700mm. The adjuster acts as a mechanical stop to fine-tune the end position and does not lock the load without live air.
