About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-75
The AirTAC SAIJ160X350-75 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 350 mm stroke that can be fine-tuned down by up to 75 mm, creating a precise 275-350 mm usable travel window. Belonging to the 160 mm bore class, it delivers substantial thrust, generating 14074 N of push force and 9425 N of pull force at a 0.7 MPa operating pressure.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G3/4 connection. The extruded aluminum barrel incorporates sensor grooves on both sides. Because the 350 mm stroke is relatively long, the 40 mm rod diameter and M36x2 rod thread provide robust support, though an external guide is still recommended to manage side loads.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-75 Is Used
Variable End-Stop Configuration
Dial in the exact 275-350 mm retraction point during machine setup to accommodate different material thicknesses without physically replacing the cylinder.
Heavy-Duty Product Changeover
Leverage the 14074 N push force to move heavy pallets or workpieces, quickly adjusting the stroke by up to 75 mm when switching production runs.
Precision Pressing Operations
Use the fine rear adjustment to set precise bottoming positions for pressing or forming tasks, ensuring consistent depth across multiple cycles.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-75 the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high force alongside flexible end-positioning. If the 10053 N push force at 0.5 MPa from a 160 mm bore is excessive, stepping down to a 125 mm bore yields 6136 N, whereas moving up to a 200 mm bore provides 15708 N. The adjustable stroke is chosen over a fixed SAI cylinder to allow rapid commissioning fine-tuning or product-size changeovers without swapping the actuator or adding external stops.
For a drop-in ISO 15552 replacement, match the 160 mm bore, 350 mm stroke, 75 mm adjustment, PT G3/4 port, and SUS304 rod material. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for position holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160BX350-75 FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. The maximum push force is 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 350 mm nominal length, providing a usable travel window of 275-350 mm. It functions as a mechanical stop and does not lock the load without continuous air pressure.
