About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-50
The AirTAC SAIJ160X90-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. Its 90mm nominal stroke can be dialed back by up to 50mm, creating a highly versatile 40-90mm usable travel window. This built-in adjustability allows operators to fine-tune end positions during commissioning without swapping out the entire actuator.
This large-bore unit features a robust 40mm piston rod and a PT tapered G3/4 port to handle high flow demands. The rod is constructed from SUS420J2 stainless steel (option A) for enhanced durability against moisture, and the extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at speeds between 30-500mm/s and relies on adjustable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-50 Is Used
Press Fit Tuning
Dial in the exact 40-90mm insertion depth for heavy press-fit operations during initial machine commissioning without needing custom spacers.
Product Changeovers
Quickly adjust the rear stopper to accommodate different product heights on a high-force assembly line, reducing setup downtime between batches.
Heavy Material Forming
Leverage the 10053N push force to form or stamp thick materials, using the adjustable end-stop to control the precise deformation depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-50 the Right Cylinder?
Selecting this 160mm bore actuator makes sense when your application requires substantial thrust—such as the 10053N push force at 0.5 MPa—but still needs precise mechanical end-position tuning within a 40-90mm window. If your setup requires less force, stepping down to a 125mm bore provides 6136N of push force, whereas moving up to a 200mm bore yields 15708N. Because the stroke is relatively short at 90mm, an external guide is less critical here, but the substantial 40mm rod diameter readily handles high side loads.
Choose the SAIJ adjustable design over a fixed-stroke SAI when you anticipate product changeovers or need to dial in exact stopping points on the fly. Remember that the rear adjuster functions strictly as a travel stop, not a locking device; the cylinder cannot hold a load without live air pressure. For load-holding requirements, consider an external pilot-operated check valve or the AirTAC SAIL lock variant. This model uses a PT port thread, omits a magnet, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces.

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 SAIJ160AX90-50 FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides a push force of 10053N and a pull force of 9425N. If operating at 0.7 MPa, the push force increases to 14074N.
The rear adjusting screw acts as an external stopper that mechanically limits the piston's travel. For this 90mm nominal stroke model, you can trim the effective stroke back by up to 50mm, resulting in a usable travel window of 40-90mm. It only sets the end position and does not lock the load without air pressure.
