About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-10
The AirTAC SAIJ100X30-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that dials back the 30 mm nominal travel to a precise 20-30 mm window. In this configuration, the unit delivers 3927 N of push force and 3681 N of pull force at a 0.5 MPa operating pressure, utilizing a robust M20x1.5 rod thread and G1/2 porting. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback integration.
Built with a SUS304 stainless steel rod (option B) and PT tapered port threads, this model is tailored for environments demanding higher corrosion resistance. The rear adjuster functions strictly as a mechanical stop for end-position tuning during commissioning; it does not lock the load, so maintaining position without live air requires an external rod lock or a SAIL cylinder. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-10 Is Used
Precision End-Stop Tuning
Dial in the exact 20 to 30 mm travel distance during machine commissioning to accommodate varying workpiece thicknesses without external physical stops.
Product Changeover
Quickly adjust the retract end-position on automated assembly lines when switching between different product sizes, minimizing downtime.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and PT tapered ports in manufacturing environments where moisture or light chemicals are present.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-10 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 2513 N push at 0.5 MPa) is insufficient for your workpiece demands, but a 125 mm bore (6136 N) would be excessive overkill. The 10 mm adjustment range is ideal for machinery requiring fine end-stop tuning during product changeovers, preventing the need to physically swap out a fixed-stroke SAI cylinder. Because the nominal 30 mm stroke is short, side-load risks are minimal, but always ensure the rod thread matches your mounting interface. For load-holding applications without continuous air pressure, consider a BSAI clamp-lock cylinder instead of relying on the SAIJ adjuster.
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 SAIJ100BX30-10 FAQ
At 0.5 MPa, the SAIJ100X30-10 provides 3927 N of push force and 3681 N of pull force. If you need higher force, stepping up to a 125 mm bore yields 6136 N at the same pressure.
The rear adjuster acts as a mechanical stop that shortens the 30 mm nominal stroke, giving you an adjustable travel window between 20 and 30 mm. It only sets the end position and does not lock the load without live air pressure.
