About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-75
The AirTAC SAIJ160X240-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down by up to 75 mm. This yields a usable stroke window of 165 to 240 mm, letting you dial in the exact end position during commissioning without swapping out the unit. Built with a 160 mm bore, it delivers substantial thrust, pushing 14074 N at 0.7 MPa and pulling 9425 N at 0.5 MPa.
This model incorporates a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though position sensing requires adding a magnet. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-75 Is Used
Variable End-Stop Positioning
Dial in the retract distance from 165 to 240 mm on the fly to accommodate different material thicknesses during machine setup without changing hardware.
Heavy Assembly Press
Leverage the 14074 N push force at 0.7 MPa for robust clamping and pressing operations, using the fine adjustment to prevent over-travel.
Corrosive Environment Actuation
Rely on the SUS304 stainless steel rod for reliable performance in packaging or processing lines where moisture or corrosive elements are present.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-75 the Right Cylinder?
Choose this 160 mm bore when you need heavy force in the 9425 to 14074 N range and require on-the-fly end-position tuning for product changeovers. If your application demands less force, stepping down to a 125 mm bore provides 8590 N of push force at 0.7 MPa. The 75 mm adjustment range is ideal for machinery processing varying part sizes, providing far greater setup flexibility than a fixed-stroke SAI cylinder. Because the stroke is 240 mm, an external guide is recommended to prevent excessive side-loading on the rod.
For load-holding without continuous air pressure, the rear stopper cannot act as a lock; you should integrate an external rod lock or select the SAIL or BSAI series. This SAIJ unit is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. It operates at speeds of 30-500 mm/s and uses a G3/4 port.

- ✓ 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 SAIJ160BX240-75 FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 10592 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the nominal 240 mm stroke by up to 75 mm, resulting in an effective travel window of 165 to 240 mm. It only decelerates and sets the end position; it does not lock the load without live air pressure.
