About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-40
The AirTAC SAIJ160X800-40 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a 760-800mm usable travel window, allowing you to dial back the nominal 800mm stroke by up to 40mm during commissioning without adding external stops. It belongs in the heavy-force class, delivering 10053N of push thrust and 9425N of pull thrust at 0.5 MPa.
This model uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a travel stop to set end-position deceleration and is not a locking device.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-40 Is Used
Heavy Press Fine-Tuning
Dial in the exact 760-800mm end position for large pressing operations during setup, ensuring precise contact without swapping out the entire cylinder.
Product Changeover Stops
Adjust the rear stopper by up to 40mm to accommodate different package lengths on a heavy-duty conveyor line without mechanical modifications.
Long-Travel Machine Setup
Set precise deceleration points for long-throw automated machinery, using the rear adjuster to fine-tune the travel end during initial commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-40 the Right Cylinder?
Choose this 160mm bore when 10053N of push force at 0.5 MPa is required, or step down to the 125mm bore (6136N) for lighter loads. The adjustable stroke is ideal for product changeovers where exact end-of-travel positioning varies slightly. For load-holding without live air pressure, note that the rear adjuster on this cylinder is only a stop; you must use a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock. When replacing an ISO 15552 cylinder, match the 800mm stroke, 40mm adjustment, PT G3/4 ports, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 800mm stroke is long, an external guide is recommended to manage side-load and prevent rod bending.
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 SAIJ160AX800-40 FAQ
At 0.5 MPa, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. It operates at a speed range of 30-500 mm/s.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from 800mm down to 760mm. It sets the end position but does not lock the load without live air pressure.
