About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-40
The AirTAC SAIJ160X650-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 650 mm travel by up to 40 mm. This yields a usable end-position window of 610 to 650 mm, enabling precise fine-tuning during commissioning without swapping the barrel or adding external stops. Built with a SUS420J2 stainless steel rod, it handles heavy loads with a 14074 N push force at 0.7 MPa.
This heavy-duty actuator features PT tapered ports and runs at 30-500 mm/s. The rear adjuster acts purely as a travel stop to set the deceleration point alongside the variable air cushions; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-40 Is Used
Heavy Press Tuning
Dial in the exact 610-650 mm end position during machine commissioning to perfect pressing depth without changing hardware.
Product Changeover
Quickly adjust the rear stopper to accommodate varying product lengths on a high-tonnage fabrication line.
Variable End Stops
Set precise retract limits for heavy material handling fixtures where standard fixed-stroke cylinders fall short.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-40 the Right Cylinder?
Selecting this 160 mm bore unit makes sense when your application requires the 10053 N push force at 0.5 MPa (or 14074 N at 0.7 MPa) alongside variable end-stops for product-size changeovers. If you need less force, stepping down to the 125 mm bore provides 6136 N at 0.5 MPa, whereas moving up to the 200 mm bore yields 15708 N. Because the 650 mm stroke is substantial and the rod is long, you must use an external guide to prevent side-loading damage, as the M36x2 rod thread alone cannot support unguided lateral forces.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 650 mm stroke, PT ports, and the 40 mm adjustment code. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants. This model has no magnet, so it requires external sensing if position feedback is needed.
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 SAIJ160AX650-40 FAQ
This 160 mm bore cylinder provides a push force of 10053 N at 0.5 MPa and 14074 N at 0.7 MPa, with a pull force of 9425 N at 0.5 MPa.
The rear adjuster screw lets you trim the effective travel from the 650 mm nominal stroke down to 610 mm, creating a 610-650 mm usable window. It functions as a mechanical stop and does not lock the load without live air.
