About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-75S
The AirTAC SAIJ160X170-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, pushing with 14074N at 0.7 MPa and pulling with 9425N at 0.5 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE solid-state switches fitted into the dual-sided sensor grooves.
This specific SKU features a 170 mm nominal stroke with a 75 mm adjustment range, yielding a usable travel window of 95 to 170 mm. This wide window allows you to dial back the retract end-position precisely during commissioning without adding external stops. The adjuster acts purely as a travel stop for deceleration, not a load-holding lock; for dead-air pressure holding, a SAIL or BSAI variant is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-75S Is Used
Heavy Machinery Setup
Fine-tune the retract distance on large presses during initial machine commissioning to accommodate varying material thicknesses without external stopper hardware.
Product Size Changeover
Rapidly adjust the 95-170 mm travel window on automated assembly lines when switching between different product sizes, minimizing downtime.
Variable End-Stop Positioning
Dial in the exact retract position for high-force clamping or forming operations, ensuring precise contact without over-traveling the mechanism.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-75S the Right Cylinder?
Select this 160 mm bore cylinder when your application requires high force (up to 18095N push at 0.9 MPa) and variable end-stop positioning within a 95-170 mm window. If your force requirements are lower, stepping down to a 125 mm bore yields 8590N push at 0.7 MPa. Conversely, if you need more force, the 200 mm bore provides 21991N push at 0.7 MPa.
This adjustable model is chosen over a fixed-stroke SAI when product changeovers require rapid end-position retuning without physically swapping the cylinder. It features a PT tapered port and carbon steel rod. Because the 170 mm stroke is below the 300 mm threshold, external side-load guiding is less critical, though the robust 40 mm rod and M36x2 thread handle substantial mechanical stress. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160X170-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074N of push force and 13194N of pull force. At the maximum operating pressure of 1.0 MPa, it achieves 18095N of push force.
The rear adjuster screw allows you to mechanically shorten the effective stroke by up to 75 mm from the 170 mm nominal length, providing a usable travel window of 95 to 170 mm. This stopper only sets the end position and does not hold the load without live air pressure.
