About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-10
The AirTAC SAIJ160X85-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 75 to 85 mm for precise end-position tuning during commissioning. It delivers a robust 14074 N of push force at 0.7 MPa, making it suitable for heavy-duty machinery. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This variant uses an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance compared to standard carbon steel. It features PT tapered port threading and a 40 mm cushion length at both ends to absorb kinetic energy. The rear adjuster acts strictly as a travel stop to decelerate the stroke end, not as a lock, so live air pressure is required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-10 Is Used
Heavy Press Damping
Uses the 40 mm cushion and 10 mm rear stopper to fine-tune the end position of high-force pressing operations.
Product Changeover
Adjusts the 75-85 mm travel window rapidly on automated lines when switching to different material thicknesses.
Heavy Machinery Actuation
Provides 14074 N of thrust for moving substantial masses while allowing exact end-stop calibration.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-10 the Right Cylinder?
Choose this 160 mm bore when an application requires approximately 14074 N of push force at 0.7 MPa, which sits between the 80 mm bore (3518 N) and the 200 mm bore (21991 N). An adjustable stroke is ideal for production lines that undergo frequent product-size changeovers, allowing operators to fine-tune the 75-85 mm travel window without swapping cylinders or adding external stops. Because the stroke is 85 mm, side-load risks are minimal, but external guiding is recommended for heavy loads. For load-holding without live air pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster does not function as a brake. ISO 15552 replacement matches require a 160 mm bore, 85 mm stroke, 10 mm adjustment, PT G3/4 port, and standard mounting.
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 SAIJ160AX85-10 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw allows you to shorten the nominal 85 mm stroke by up to 10 mm, creating a usable travel window of 75 to 85 mm. It functions as an external stop to set the end position and does not lock the load without air pressure.
