About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-75S
The AirTAC SAIJ160X350-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 275 to 350 mm usable travel window. It delivers substantial thrust, pushing with 14074 N and pulling with 9425 N at 0.7 MPa. Equipped with a SUS304 stainless steel rod and PT tapered ports, this unit is built for robust industrial performance.
The external adjuster functions as a hard stop to fine-tune the retract end position during commissioning or product changeovers without swapping the cylinder. It is not a locking mechanism, so live air is required to hold the load. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-75S Is Used
Variable End-Stop Machining
Dial in the 275 to 350 mm travel window to accommodate multiple part lengths on a single fixture without machining custom spacers.
Product Changeover Diverter
Quickly reposition the retract stopper during line format changes to route different package sizes down the handling conveyor.
Commissioning Stroke Tuning
Fine-tune the final end-position during machine setup to absorb mechanical tolerance stacks without replacing the actuator.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-75S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore falls short on power, as the 80 mm generates 3518 N at 0.7 MPa compared to this model's 14074 N. The 75 mm adjustment range is ideal for machinery requiring precise variable end-stops across different product sizes. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles.
For load-holding applications without continuous air pressure, this cylinder is insufficient; consider an AirTAC SAIL pneumatic lock, BSAI clamp-lock, or an external rod lock. Because the 350 mm stroke is substantial, the 40 mm rod diameter handles high side loads, but an external guide rail is still recommended to prevent premature seal wear. This component is dimensionally interchangeable per ISO 15552 mounting interfaces.
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 SAIJ160 Adjustable Cylinder SAIJ160BX350-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. At its maximum 1.0 MPa pressure, it achieves a push force of 18095 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 350 mm down to 275 mm. It sets the end position but does not lock the load without live air pressure.
