About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-50
The AirTAC SAIJ160X650-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers heavy thrust, pushing with 14074N and pulling with 9425N at 0.7 MPa. The integrated rear stopper allows you to fine-tune the effective travel anywhere within a 600-650 mm window, providing precise end-position tuning without swapping out the entire actuator.
Equipped with a SUS420J2 stainless steel rod (material code A), this actuator handles demanding environments better than standard carbon steel. It uses PT tapered ports sized G3/4 and runs at 30-500 mm/s. The extruded aluminum barrel incorporates sensor grooves on both sides, ready to accept CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-50 Is Used
Heavy Press Tuning
Dial in the exact 600-650 mm end-stop during machine commissioning to accommodate varying material thicknesses without reprogramming motion controllers.
Product Changeover
Quickly adjust the rear stopper by up to 50 mm when switching packaging sizes on a high-thrust line, saving hours of mechanical retooling.
Large Assembly Jigs
Leverage the 14074N push force at 0.7 MPa to seat heavy components, relying on the SUS420J2 rod for durability in industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-50 the Right Cylinder?
Selecting this 160 mm bore makes sense when your application requires substantial force that a 125 mm bore cannot provide, as the 125 tops out at 8590N push at 0.7 MPa. The 50 mm adjustment range is perfect for product changeovers on a line, letting you dial in the exact end-stop mechanically rather than reprogramming fixed SAI cylinders. Because the nominal stroke is 650 mm, an external guide is strongly recommended to prevent excessive side-loading on the long, unsupported rod.
When matching an ISO 15552 replacement, verify the 160 mm bore, 650 mm stroke, PT G3/4 port, and the specific 50 mm adjustment code. Note that the rear adjuster acts strictly as a travel stop, not a lock. If you need to hold a load securely without live air pressure, look to the SAIL or BSAI series instead. Mounting options are limited to 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 SAIJ160AX650-50 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074N and a pull force of 9425N. At the maximum 1.0 MPa pressure, it achieves a push force of 18095N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 650 mm nominal stroke down to 600 mm. It only sets the end position and does not lock the load without live air pressure.
