About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-20
The AirTAC SAIJ160X90-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial back the nominal 90 mm travel by up to 20 mm, creating a precise 70-90 mm usable window. It delivers massive thrust, pushing 14074 N at 0.7 MPa, making it ideal for heavy-duty press operations. The piston rod is built from SUS420J2 stainless steel, offering high resistance to corrosion for harsh environments.
Unlike a fixed-stroke SAI, this model allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting, though position detection requires a magnet (-S) to use CMSE reed or DMSE electronic switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-20 Is Used
Press Tuning
Dial in the exact 70-90 mm end position during machine commissioning to accommodate varying material thicknesses without external stops.
Product Changeover
Quickly adjust the retract distance on the fly when switching between different product sizes on a heavy-duty assembly line.
Heavy Forming
Leverage the 14074 N push force at 0.7 MPa for metal bending or forming tasks that require precise, repeatable stroke endpoints.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-20 the Right Cylinder?
Choose this 160 mm bore when your application requires significantly more force than the 100 mm bore (5497 N push at 0.7 MPa) but less than the 200 mm class. The adjustable stroke is perfect for product changeovers or variable end-stop requirements, letting you set the exact travel distance on the machine floor.
The PT tapered port and G3/4 thread size match the standard 160 mm bore specifications. Keep in mind the rear adjuster acts strictly as a travel stop to decelerate the load, not a lock; a plain SAIJ will not hold its position without live air. For true load-holding without pressure, consider the SAIL lock or BSAI clamp-lock cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160AX90-20 FAQ
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. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw acts as an external stopper, allowing you to shorten the 90 mm nominal stroke by up to 20 mm. This creates a usable travel window of 70 to 90 mm, which can be fine-tuned during setup without replacing the cylinder.
