About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX145-10S
The AirTAC SAIJ100X145-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 135-145 mm usable travel window. Delivering 3927 N of push force at 0.5 MPa, it handles demanding positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection installation.
This variant is equipped with a SUS304 stainless steel rod for superior corrosion resistance and ships with a magnet for CMSE reed and DMSE electronic sensors. A PT tapered port thread ensures a tight pneumatic connection, while the 10 mm adjustment screw lets you fine-tune the retract end position during commissioning.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX145-10S Is Used
Precision Machining Clamping
Dial in the 135-145 mm clamping reach during machine setup to accommodate varying part tolerances without swapping cylinders.
Product Diversion Stops
Adjust the retract stop position by up to 10 mm on the fly to handle slight size variations in packages moving along the line.
Assembly Station Setup
Fine-tune the end-of-stroke position during commissioning to achieve perfect component seating using the rear adjuster.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX145-10S the Right Cylinder?
Choose this 100 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is insufficient but an 80 mm bore (2513 N) lacks the necessary thrust margin. The 10 mm adjustable end-stop is ideal for dialing in exact end positions during product changeovers without adding external stops. For any application near the 145 mm stroke length, ensure external guides support the load to prevent excessive side-loading on the rod.
To match this ISO 15552 cylinder for a replacement, verify the 100 mm bore, 145 mm stroke, 10 mm adjustment range, PT G1/2 port, and the -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true locking, consider the SAIL or BSAI series. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ100BX145-10S 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.
The rear adjusting screw acts as a mechanical stop that lets you shorten the nominal 145 mm stroke by up to 10 mm, creating a 135-145 mm usable travel window. It requires live air to function and does not lock the load in place.
