About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-10S
The AirTAC SAIJ160X850-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, generating 18095N of push force at 0.9 MPa, making it suitable for heavy-duty operations. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches housed in the dual-side sensor grooves.
This specific SKU features a 10 mm adjustment range, creating an exact usable travel window of 840-850 mm for fine-tuning the retract end position at commissioning. Built with a SUS304 stainless steel rod (code B) for superior corrosion resistance, it utilizes PT tapered port threads and operates at speeds of 30-500 mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-10S Is Used
Heavy Press Tuning
Dial in the exact 840-850 mm retract position on heavy forming presses during setup, ensuring precise bottoming depth without external stopper blocks.
Large Tooling Changeover
Adjust the end-stop quickly when switching out large machinery tooling, using the 10 mm trim window to accommodate minor variations in new fixture heights.
Corrosive Heavy Lifting
Leverage the SUS304 stainless steel rod for heavy clamping tasks in washdown or mildly corrosive environments where carbon steel rods would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-10S the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder (providing 4523N push at 0.5 MPa) lacks the necessary power for high-tonnage tasks. The adjustable stroke is ideal for applications requiring precise end-stop tuning during product changeovers without swapping the cylinder. Because the nominal stroke is 850 mm, an external guide is strongly recommended to prevent excessive side-loading on the extended rod.
For a direct ISO 15552 replacement match, verify the 160 mm bore, 850 mm stroke, 10 mm adjustment, PT port thread, and the -S magnet requirement. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ160BX850-10S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates a push force of 18095N and a pull force of 9425N. It reaches a maximum thrust of 2050 kgf at 1.0 MPa.
The rear adjusting screw allows you to shorten the effective stroke by up to 10 mm, providing a usable travel window of 840 to 850 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
