About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-20
The AirTAC SAIJ160X900-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a nominal 900 mm stroke that can be mechanically dialed back by up to 20 mm. This yields a precise 880-900 mm usable travel window, allowing you to fine-tune the retract end position at commissioning without adding external stops. It belongs to the SAIJ adjustable-stroke family, utilizing an extruded aluminum barrel rather than a tie-rod design.
Delivering 14074 N of push force at 0.7 MPa, this bore 160 unit is equipped with a robust 40 mm SUS420J2 stainless steel rod and PT tapered port threads. The rear adjuster acts purely as a travel stop to set the end position and relies on the integrated variable air cushion for deceleration; it is not a locking mechanism and will not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-20 Is Used
Heavy Machinery Setup
Dial in the exact 880-900 mm retract position during heavy equipment commissioning without swapping out the entire actuator.
Product Changeover
Quickly adjust the end-stop by up to 20 mm to accommodate varying pallet sizes on an automated conveyor line.
Large Assembly Presses
Leverage the 14074 N push force at 0.7 MPa to drive large components, using the rear stop to fine-tune the final resting depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-20 the Right Cylinder?
Select this adjustable model over a fixed-stroke SAI when your assembly requires variable end-stops or product-size changeovers on the fly. If your application demands less thrust, stepping down to a bore 125 cylinder provides 8590 N of push force at 0.5 MPa, whereas a bore 200 unit offers 21991 N at 0.7 MPa for heavier loads. To replace an ISO 15552 cylinder, match the 160 mm bore, 900 mm stroke, 20 mm adjustment, PT G3/4 port, and standard mounting interface.
Because the 900 mm stroke is substantial, the 40 mm rod will experience leverage forces under side-loading; an external guide rail is strongly recommended to prevent premature seal wear. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. For load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI cylinder instead.

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 SAIJ160AX900-20 FAQ
At an operating pressure of 0.7 MPa, this bore 160 cylinder provides a push force of 14074 N and a pull force of 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from its 900 mm nominal length down to 880 mm. This creates an 880-900 mm travel window for fine-tuning the end position without changing the cylinder itself.
