About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-50
The AirTAC SAIJ160X65-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 18095N push force at 0.9 MPa. A tapered PT G3/4 port feeds the 40mm diameter SUS420J2 stainless steel rod, providing excellent resistance to side-load wear in heavy-duty tooling. By integrating a 50mm external stopper at the rear, this model creates a highly versatile 15-65mm usable travel window, allowing you to fine-tune end positions without swapping out the entire cylinder.
Because the adjustment mechanism acts purely as a mechanical stop, it does not hold the load without live air pressure. For gravity-resistant load-holding, you would need to specify a related SAIL pneumatic lock or an external BSAI clamp-lock cylinder. The extruded aluminum barrel features sensor grooves on both sides for mounting CMSE reed or DMSE electronic solid-state switches, though this particular SKU is supplied without a magnet.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-50 Is Used
Heavy-Duty Press Tuning
Dial in the exact 15-65mm clamping travel on heavy stamping presses during initial commissioning without disassembling the tooling.
Variable Product Changeover
Rapidly adapt automated heavy-load stops on a conveyor line when switching between product families of varying dimensions.
Large Assembly Positioning
Precisely set the end-of-stroke datum for large component mating operations, leveraging the 40mm SUS420J2 rod for high side-load survival.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-50 the Right Cylinder?
Choose this 160mm bore when a 125mm cylinder (providing 11045N push at 0.9 MPa) cannot generate enough force for your heavy clamping or lifting requirement. The 50mm adjustment range is ideal for machine setups requiring frequent product-size changeovers, giving operators a variable end-stop directly at the cylinder rather than machining custom external spacers.
When replacing an ISO 15552 unit, match the 160mm bore, 65mm nominal stroke, 50mm adjustment code, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this series intentionally omits FB, CA, CB, and CR mounts. If your application requires true position holding without continuous air, pivot to an SAIL or BSAI variant.
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 SAIJ160AX65-50 FAQ
At an operating pressure of 0.9 MPa, this 160mm bore cylinder generates a push force of 18095N and a pull force of 9425N. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stopper that shortens the effective stroke from its 65mm nominal length, providing a usable travel window between 15mm and 65mm. It only dictates the end position and does not lock the load without live air pressure.
