About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-50
The AirTAC SAIJ100X160-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 160 mm travel by up to 50 mm. This yields a precise 110-160 mm usable window, perfect for fine-tuning end positions during commissioning without swapping out the entire actuator. It delivers robust thrust, pushing 3927 N and pulling 3681 N at 0.5 MPa, scaling up to 7068 N push at 0.9 MPa.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE solid-state switches if you add a magnet later. Remember that the rear adjuster acts purely as a travel stop to set deceleration, not as a lock, so live air is required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-50 Is Used
Machine Changeover
Dial in the 110-160 mm travel window during product-size line changes without adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end position at commissioning to absorb mechanical tolerances and optimize the pressing force.
Heavy Pressing
Leverage the 7068 N push force at 0.9 MPa for robust clamping and forming tasks within the adjustable travel range.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-50 the Right Cylinder?
Select this 100 mm bore when your application requires high force in the 3927 N range at 0.5 MPa, stepping up from a 63 mm bore that provides 1559 N. The adjustable stroke is chosen over a fixed SAI model when you need variable end-stops for machine changeover or product-size adjustments. To match this ISO 15552 cylinder for replacement, verify the 100 mm bore, 160 mm stroke, 50 mm adjustment, PT G1/2 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting.
Because the stroke is 160 mm, the 25 mm rod diameter and M20x1.5 rod thread handle side loads well, but an external guide is recommended for heavy offsets. For applications requiring the load to be held without live air pressure, this standard SAIJ is insufficient; consider the SAIL air-released lock or BSAI clamp-lock 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 SAIJ100BX160-50 FAQ
The rear adjuster acts as an external stopper that lets you mechanically shorten the 160 mm nominal stroke by up to 50 mm, creating a 110-160 mm usable travel window. It only sets the travel end and deceleration; it does not lock the load without live air pressure.
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 801 kgf.
