Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-10
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-10
The AirTAC SAIJ160X900-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 14074N of push force at 0.7 MPa. Its 900mm stroke is fully standard for this bore, yet the 10mm adjustment screw lets you dial the effective travel back to a minimum of 890mm. This built-in tuning capability eliminates the need to physically swap cylinders or bolt on external stops when refining end positions during commissioning.
This heavy-duty actuator features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads for its G3/4 connections. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to directly mount CMSE reed or DMSE solid-state switches. Remember that the rear adjuster functions strictly as a travel stop to set deceleration endpoints, not as a lock; it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-10 Is Used
Heavy Press Positioning
Fine-tune the 890-900mm travel window during setup to precisely dial in the clamping end-position on large assemblies without swapping out the physical actuator.
Pallet Changeover Stops
Adjust the retract stopper by up to 10mm on the fly to accommodate slightly different pallet lengths running on the same high-thrust conveyor line.
Long-Stroke Ejection
Utilize the massive 18095N push force at 0.9 MPa to eject heavy finished goods from a machine bed, tweaking the final ejection point via the rear screw.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-10 the Right Cylinder?
Choose this 160mm bore when an 80mm bore is insufficient, as stepping down to an SAIJ80X900 yields only 2268N of pull force at 0.5 MPa compared to the 9425N available here. The 10mm adjustment window is ideal for product-size changeovers on a line, allowing operators to fine-tune the retract end-position without changing the cylinder. Because the 900mm stroke creates a long unsupported rod extension, an external guide is strongly recommended to prevent excessive side-loading and premature seal wear.
To match this ISO 15552 cylinder for a direct replacement, verify the 160mm bore, 900mm stroke, 10mm adjustment code, PT G3/4 port, and SUS304 (B) rod material. Note that SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. If your application requires true load-holding without live air, consider the SAIL air-released lock or BSAI clamp-lock variants instead of relying on the adjuster.

- ✓ 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 SAIJ160BX900-10 FAQ
At 0.5 MPa it provides 10053N push and 9425N pull force. At 0.9 MPa, the push force increases to 18095N, with a maximum rated force of 2050 kgf at 1.0 MPa.
The rear external screw acts as a stopper that lets you shorten the effective travel from 900mm down to 890mm. It sets the deceleration end-point but does not lock the load without live air.
