About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX145-30S
The AirTAC SAIJ100X145-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 115 to 145 mm, allowing you to dial back the nominal 145 mm stroke by up to 30 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads while maintaining standard ISO 15552 mounting dimensions.
This variant is equipped with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel features sensor grooves on three sides, supporting AirTAC CMSE reed and DMSE solid-state switches. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX145-30S Is Used
Product Changeover
Quickly reconfigure the 115-145 mm travel window for varying product lengths on a packaging line without disassembling the cylinder assembly.
End-Position Tuning
Dial in the exact retraction point during machine commissioning using the 30 mm rear stopper screw, eliminating the need for external spacers.
Heavy-Duty Forming
Leverage the 3927 N push force at 0.5 MPa for pressing and forming tasks, utilizing the SUS304 rod in environments requiring high corrosion resistance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX145-30S the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (1559 N at 0.5 MPa) is insufficient and an 80 mm bore (2513 N) still lacks the necessary thrust. The adjustable stroke is ideal for product changeovers, letting you fine-tune the end position without swapping hardware. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is only a stop.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 145 mm stroke, 30 mm adjustment, PT port thread, and the -S magnet option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300 mm, side-load stress is manageable, but long unsupported loads should still use an external guide.
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 SAIJ100BX145-30S FAQ
The rear adjuster allows you to trim the effective stroke by up to 30 mm, providing a usable travel window of 115 to 145 mm. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, it generates 3927 N of push force and 3681 N of pull force. The -S option includes a magnet compatible with AirTAC CMSE reed and DMSE electronic sensors.
