About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX145-10
The AirTAC SAIJ100X145-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 145 mm stroke with a 10 mm trim range, yielding a precise 135-145 mm usable travel window for fine-tuning the retract end position during commissioning. Belonging to the 100 mm bore class, it delivers 5497 N of push force at 0.7 MPa.
This variant is configured with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes dual sensor grooves, allowing you to add CMSE or DMSE switches if position detection is needed later. The rear adjuster functions strictly as a mechanical stop to set the travel limit, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX145-10 Is Used
Machine Changeover
Dial in the 135-145 mm travel window during product size changes without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract end position at commissioning to absorb mechanical tolerances, ensuring precise placement of heavy 100 mm bore loads.
Assembly Pressing
Leverage 5497 N of push force at 0.7 MPa for pressing operations while using the rear screw to set exact material engagement depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX145-10 the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust, stepping up from a 63 mm bore that yields 2182 N at 0.7 MPa. The 10 mm adjustable window is ideal for variable end-stops or product-size changeovers, preventing the need to swap out a fixed-stroke SAI cylinder. For an exact ISO 15552 replacement match, verify the 145 mm stroke, 10 mm adjustment, PT port thread, and your required mounting style.
The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR options. Because this unit lacks a magnet, it cannot host reed or solid-state sensors without modification. If your setup requires holding a load without continuous air pressure, integrate an external rod lock or pilot-operated check valve, or select an AirTAC SAIL or BSAI cylinder 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 SAIJ100BX145-10 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it achieves 801 kgf.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 10 mm. This creates a 135-145 mm usable stroke window, allowing you to set the exact end position without changing the cylinder.
