About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-30
The AirTAC SAIJ100X145-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 115-145 mm, allowing you to dial back the 145 mm nominal stroke by up to 30 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it is built for heavy-duty positioning tasks.
This model features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes dual sensor grooves, while the mounting interface strictly supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-30 Is Used
Product Changeovers
Dial in the exact end-stop position on the fly when switching between product sizes on a packaging line, utilizing the 115-145 mm travel window.
Machine Commissioning
Fine-tune the final retract position during setup without swapping out the entire cylinder or adding complex external stopper blocks.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or tooling carriages, adjusting the stroke to match fixture variations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-30 the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust—such as 3927 N at 0.5 MPa or 7068 N at 0.9 MPa—combined with variable end-position tuning. The 30 mm adjustment window is perfect for product changeovers, eliminating the need to physically swap cylinders or bolt on external stops. If your setup requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa.
Because the 145 mm stroke is under the 300 mm threshold, standard side-load concerns are minimized, though the robust 25 mm piston rod and M20x1.5 rod thread provide excellent rigidity. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ100AX145-30 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 145 mm nominal stroke by up to 30 mm. This creates a usable travel window of 115-145 mm for fine-tuning end positions without replacing the cylinder.
