About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-100S
The AirTAC SAIJ160X800-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits an exact 700-800 mm usable travel window. It delivers robust thrust, pushing with 14074 N at 0.7 MPa and pulling with 9425 N. The 40 mm diameter piston rod is paired with a PT tapered G3/4 port to handle high flow demands.
This specific SKU integrates a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The rear adjustment mechanism acts purely as a travel stop to fine-tune the retract end position during commissioning, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-100S Is Used
Heavy Press Tuning
Dial in the exact 700-800 mm end-stop during machine commissioning to accommodate varying material thicknesses in large forming presses.
Product Size Changeover
Quickly adjust the retract distance on packaging lines handling different pallet sizes without physically swapping out the entire actuator.
Automated Assembly Stops
Set precise lower-end positions for heavy automotive component placement, relying on the 14074 N push force at 0.7 MPa to seat large parts.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-100S the Right Cylinder?
Choose this 160 mm bore when an application requires heavy thrust within a 700-800 mm travel window, stepping up from a 125 mm bore that offers 8590 N push at 0.5 MPa. The adjustable rear stopper is selected over a fixed-stroke SAI cylinder when machinery requires variable end-position tuning during product changeovers. Because the nominal stroke is 800 mm, an external guide is strongly recommended to prevent excessive side-loading on the long unsupported rod.
To match this ISO 15552 cylinder for a direct replacement, verify the 160 mm bore, 800 mm nominal stroke, 100 mm adjustment range, PT G3/4 port, and the -S magnet. Remember that the rear adjuster only sets the travel end and deceleration; it is not a lock. For true load-holding without live pressure, consider an AirTAC SAIL or BSAI cylinder instead. This model supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting styles.

- ✓ 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 SAIJ160BX800-100S FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 100 mm, providing a usable travel window of 700-800 mm. It sets the end position and works with the air cushion for deceleration, but it does not lock or hold the load without continuous air pressure.
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. The operational speed range for this model is 30-500 mm/s.
