About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX240-10
The AirTAC SAIJ100X240-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 240 mm stroke that can be dialed back by up to 10 mm, creating a 230-240 mm usable travel window for precise end-position tuning during commissioning. In the 100 mm bore class, it delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa, utilizing a G1/2 port and 36 mm cushions at both ends.
This variant uses a SUS304 stainless steel rod (material code B) for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX240-10 Is Used
Machine Setup Tuning
Dial in the exact 230-240 mm retract position during machine commissioning to align heavy tooling without machining new stop blocks.
Product Changeover
Quickly adjust the end-stop by up to 10 mm when a packaging line switches to a different carton size or pallet height.
Heavy Press Positioning
Leverage the 3927 N push force at 0.5 MPa to press or seat large components while retaining fine control over the final stroke end-point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX240-10 the Right Cylinder?
Select this 100 mm bore when an application requires substantial thrust—up to 5497 N at 0.7 MPa—combined with variable end-stop positioning. The 10 mm rear adjustment screw allows operators to fine-tune the retract position without swapping the cylinder or adding external mechanical stops. If an application requires less force, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 240 mm stroke, 10 mm adjustment, PT tapered port threads, and the chosen mounting bracket. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. The 25 mm rod and M20x1.5 thread handle high side loads, but the 240 mm stroke still benefits from an external guide for heavy loads.
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 SAIJ100BX240-10 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
A rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective travel from the nominal 240 mm down to 230 mm. This creates a 230-240 mm adjustable window for fine-tuning the end position without replacing the cylinder.
