About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-40
The AirTAC SAIJ160X600-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 600 mm travel by up to 40 mm for a usable window of 560 to 600 mm. This fine-tuning capability at commissioning eliminates the need to swap cylinders or bolt on external stops when aligning heavy machinery. Delivering massive thrust up to 18095 N at 0.9 MPa, it handles substantial loads with ease.
This specific configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel integrates sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state sensors. The rear adjuster acts purely as a mechanical stop to set deceleration and end positions, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-40 Is Used
Heavy Press Tuning
Fine-tune the exact bottom dead center of a 600 mm forming press stroke within a 40 mm window without physically replacing the actuator.
Product Size Changeover
Rapidly adjust the retract end-position on automated packaging lines when switching between different large-format product sizes.
Automated Assembly Stops
Set precise mechanical travel limits for heavy-duty assembly stations, using the rear stopper to guarantee consistent end-positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-40 the Right Cylinder?
Selecting this 160 mm bore model is appropriate when your application requires extreme force, stepping up from the 100 mm bore which provides 7068 N push at 0.9 MPa. The adjustable stroke is chosen over a fixed SAI cylinder when a machine setup requires variable end-stops or precise product-size changeovers. To replace an existing ISO 15552 cylinder, match the 160 mm bore, 600 mm stroke, 40 mm adjustment, PT G3/4 ports, and the desired mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the 600 mm stroke creates a long lever arm, an external guide is strongly recommended to prevent excessive side-load on the rod. For applications that require true load-holding without continuous air pressure, this cylinder is insufficient; consider the SAIL air-released lock or BSAI clamp-lock versions instead.
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 SAIJ160AX600-40 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 600 mm down to as little as 560 mm, providing a 40 mm tuning window. It sets the end position but does not lock the load without live air pressure.
At 0.9 MPa operating pressure, the SAIJ160X600-40 provides a push force of 18095 N. At 0.5 MPa, the push force is 10053 N.
