About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-30S
The AirTAC SAIJ100X115-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 115 mm stroke that can be fine-tuned down by up to 30 mm, creating an exact 85-115 mm usable travel window during commissioning. Delivering a robust 3927 N push force at 0.5 MPa, it handles heavy positioning tasks with ease.
This SKU features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a built-in magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads ensure a secure pneumatic connection.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-30S Is Used
Product Size Changeovers
Dial in the 85-115 mm travel window instantly on the rear adjuster to accommodate varying package sizes on a packaging line without swapping hardware.
Machine Setup Calibration
Fine-tune the exact end-of-stroke position during initial commissioning to perfect pressing or seating forces without machining custom spacers.
Heavy Component Positioning
Leverage the 3927 N push force at 0.5 MPa to shift heavy assemblies into place, using the adjustable stop to account for mechanical tolerance stack-up.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-30S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial thrust—such as the 3927 N push force at 0.5 MPa—combined with variable end-stop positioning. If a smaller footprint is acceptable, a 80 mm bore provides 2513 N at 0.5 MPa; stepping up to this 100 mm bore is necessary for heavier loads. The adjustable stroke is chosen over a fixed SAI cylinder when you need to fine-tune the retract position on the fly without adding external stops.
For ISO 15552 replacement matching, verify the 100 mm bore, 115 mm stroke, 30 mm adjustment, PT port thread, and the -S magnet option. Mounting is limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100AX115-30S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from its 115 mm nominal length down to a minimum of 85 mm. It sets the travel end position but does not lock the load without continuous air pressure.
