Airtac SAIJ160 Adjustable Cylinder SAIJ160BX30-20S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX30-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 30mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX30-20S
The AirTAC SAIJ160X30-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 14074N at 0.7 MPa. The integrated adjustment screw allows you to trim the nominal 30mm stroke back by up to 20mm, creating a highly precise 10-30mm usable travel window for exact end-position tuning during commissioning. It features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
This 160mm bore actuator uses G3/4 PT tapered ports and relies on 50mm air cushions at both ends to decelerate heavy loads. The rear adjuster functions strictly as a mechanical stop to set the travel end, not as a load-holding lock; for position holding without live air pressure, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX30-20S Is Used
Heavy Press Fitting
Dial in the exact 10-30mm travel window during machine setup to press large bearings without overstressing the tooling.
Product Size Changeover
Quickly adjust the rear stopper on a packaging line to accommodate varying product heights without replacing the actuator.
Short-Stroke Clamping
Provide massive 14074N clamping force for large weldments, using the rear screw to fine-tune the clamping position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX30-20S the Right Cylinder?
Choose this 160mm bore model when your application requires the immense pull force of 9425N at 0.5 MPa and a very short, highly tunable travel window. If you need less force, stepping down to the 125mm bore yields 5734N pull at 0.5 MPa, whereas moving up to the 200mm bore provides 15080N pull. The adjustable stroke is ideal for variable end-stops and machine changeover without swapping cylinders, unlike a fixed-stroke SAI model. To match this ISO 15552 replacement exactly, verify the 160mm bore, 30mm stroke, 20mm adjustment, G3/4 PT ports, SUS304 (B) rod, -S magnet, and the reduced mounting set.

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 SAIJ160BX30-20S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder generates a push force of 14074N and a pull force of 12698N. At its maximum rated pressure of 1.0 MPa, it can deliver up to 2050 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 20mm from the nominal 30mm, providing a usable travel window of 10-30mm. This enables fine end-position tuning at commissioning without adding external stops.
