About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-50
The AirTAC SAIJ100X145-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 145 mm stroke by up to 50 mm. This yields a usable travel window of 95-145 mm, providing precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads.
Delivering 3927 N of push force and 3681 N of pull force at 0.5 MPa, this 100 mm bore actuator handles heavy loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts as a travel stop to set deceleration and end limits, but it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-50 Is Used
Machine Changeover
Dial in the 95-145 mm travel window during product size changeovers to set new end positions without machining new stop blocks.
Press Fit Tuning
Fine-tune the retraction end position during commissioning to perfect pressing depths on the assembly line.
Diversion Gate Control
Adjust the actuation distance of sorting gates on the fly to accommodate varying package dimensions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-50 the Right Cylinder?
Select this 100 mm bore when an application requires substantial thrust—such as 3927 N at 0.5 MPa—and needs on-the-fly travel adjustments within a 95-145 mm window. If you need less force, stepping down to an 80 mm bore yields 2513 N push force at 0.5 MPa. Because the stroke is 145 mm, side loads are moderate, but always ensure external guiding for heavy payloads to prevent rod binding.
Choose this adjustable-stroke SAIJ variant over a fixed SAI when machine setups require variable end-stops or frequent product-size changeovers. To replace an ISO 15552 cylinder, match the 100 mm bore, 145 mm stroke, 50 mm adjust code, PT port threads, and the desired mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). For applications that must hold a load mechanically without continuous air pressure, select a SAIL or BSAI series cylinder instead, as the SAIJ adjuster is a stop, not a lock.
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 SAIJ100AX145-50 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 adjuster screw acts as a mechanical stop that lets you trim the effective travel back from the 145 mm nominal stroke by up to 50 mm, creating a 95-145 mm usable window. It sets the end position but does not lock or hold the load without live air pressure.
