About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-100S
The AirTAC SAIJ160X300-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 18095N of push force at 0.9 MPa. Its 300 mm nominal stroke can be dialed back by up to 100 mm, providing an exact 200-300 mm usable travel window for precise end-position tuning during commissioning. This built-in adjuster eliminates the need to swap cylinders or bolt on external stoppers when finalizing machine setup.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and carries the -S magnet option for seamless integration with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the G3/4 PT tapered ports ensure high flow for the 30-500 mm/s speed range. It utilizes the standard SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-100S Is Used
Heavy Machinery Changeover
Dial in the 200-300 mm travel window during product family changeovers to accommodate different large-assembly dimensions without physically swapping actuators.
Precision Pressing Setup
Leverage the 100 mm adjustment screw to fine-tune the exact bottoming position for heavy pressing tasks, ensuring perfect contact without over-stroking.
Material Handling Stops
Adjust the retract end-stop on the fly to handle varying pallet sizes on a heavy-duty conveyor line, using the SUS304 rod to withstand harsh environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-100S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires heavy thrust up to 18095N alongside variable end-stop positioning. If you need less force, stepping down to a 125 mm bore yields 11045N of push at 0.9 MPa, while stepping up to a 200 mm bore provides 28274N. The adjustable stroke is ideal for product-size changeovers on a line, allowing operators to fine-tune the retract position without changing the cylinder. Because the 300 mm stroke is relatively long, ensure adequate external guiding to prevent excessive side-loading on the rod.
For a true ISO 15552 replacement match, verify the 160 mm bore, 300 mm stroke, 100 mm adjustment range, G3/4 PT ports, SUS304 rod, and the -S magnet requirement. Remember that the rear adjuster functions strictly as a travel stop, not a lock; a plain SAIJ will not hold a load without live air pressure. For dead-pilot or fail-safe load holding, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX300-100S FAQ
The rear adjuster acts as an external mechanical stop that shortens the effective travel. For this model, the 300 mm stroke can be trimmed back by up to 100 mm, resulting in a usable travel window of 200-300 mm. It only sets the travel end and does not lock the load without live air.
Operating at 0.9 MPa, the SAIJ160X300-100-S generates a push force of 18095N and a pull force of 9425N. At 0.5 MPa, the push force is 10053N. The cylinder operates at speeds between 30-500 mm/s.
