About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-20S
The AirTAC SAIJ160X65-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 65 mm travel by up to 20 mm. This yields a precise 45-65 mm usable stroke window, perfect for fine-tuning end positions during commissioning without swapping hardware. As a 160 mm bore actuator, it delivers substantial thrust, generating 14074 N of push force at 0.7 MPa.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet for CMSE reed and DMSE electronic sensors. Fluid control is managed via G3/4 PT tapered ports, while the extruded aluminum barrel incorporates sensor grooves on both sides. The rear adjuster acts purely as a travel stop to set deceleration, meaning it will not hold the load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-20S Is Used
Press Stroke Calibration
Dial in the exact 45-65 mm end position during machine setup to accommodate material thickness variations without changing the cylinder.
Product Changeover Stops
Adjust the rear stopper on the fly for different package sizes on a packaging line, ensuring precise positioning without external hardware.
Heavy Duty Clamping
Leverage the 14074 N push force at 0.7 MPa to secure heavy workpieces, using the adjustable stroke to fine-tune the clamp contact point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-20S the Right Cylinder?
Select this 160 mm bore model when an application demands high force, such as replacing a smaller 125 mm cylinder that only provides 8590 N at 0.7 MPa. The adjustable 45-65 mm travel window is ideal for product-size changeovers on a line, providing variable end-stops without adding external mechanical stops. To match this cylinder for an ISO 15552 replacement, verify the 65 mm stroke, 20 mm adjustment range, G3/4 PT port, and the -S magnet requirement.
Because the stroke is under 300 mm, side-load stress on the 40 mm SUS304 rod is minimized, though external guides are still recommended for heavy lateral loads. If your process requires true load-holding without live air pressure, a plain SAIJ is insufficient; consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. Mounting options for this series include 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 SAIJ160BX65-20S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can achieve a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 65 mm nominal stroke by up to 20 mm, creating a usable travel window of 45 to 65 mm. This stopper sets the travel end and deceleration point but does not lock the load without live air.
