About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-30
The AirTAC SAIJ100X160-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 130-160mm usable travel window, letting you dial back the nominal 160mm stroke by up to 30mm during commissioning without adding external stops. The SUS420J2 stainless steel rod (code A) offers good corrosion resistance, while the G1/2 PT tapered ports handle high flow rates.
This 100mm bore generates 5497N of push force at 0.7MPa and includes variable air cushions at both ends to manage kinetic energy. The extruded aluminum barrel integrates dual sensor grooves, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear screw acts purely as a travel stop for end-position tuning, not as a load-holding lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-30 Is Used
Product Changeover Lines
Rapidly adjust the end-stop from 160mm down to 130mm when switching to a shorter product format, eliminating the need to swap out the entire cylinder assembly.
Commissioning Calibration
Fine-tune the retract travel position during machine setup to perfectly align stops without fabricating custom external spacers.
Heavy Forming Presses
Leverage the 5497N push force at 0.7MPa for high-force stamping or pressing tasks, dialing in the exact stroke depth for different material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-30 the Right Cylinder?
Choose this 100mm bore when your application requires substantial thrust, such as the 5497N push force at 0.7MPa. If you need less force, stepping down to an 80mm bore yields 3518N at the same pressure. The adjustable stroke is ideal for machines processing multiple product sizes, allowing you to fine-tune the retract end-position on the fly instead of physically swapping cylinders. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster only halts travel.
When replacing an ISO 15552 cylinder, match the 100mm bore, 160mm stroke, 30mm adjustment range, PT G1/2 port, and the required mounting accessory. Because the 160mm stroke is relatively short, side-load risks are minimal, but always guide the load externally for optimal bearing life. This configuration uses an SUS420J2 rod and lacks a magnet, so add an -S suffix if you need CMSE or DMSE electronic sensors.

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100AX160-30 FAQ
At a 0.7MPa operating pressure, this 100mm bore cylinder provides 5497N of push force and 3681N of pull force. The maximum force is 801kgf at 1.0MPa.
The rear adjuster screw lets you mechanically shorten the effective travel from the nominal 160mm down to 130mm, creating a 130-160mm usable window. It functions as a physical stop to tune end-positions, but it does not lock or hold the load without continuous air pressure.
