About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX650-10
The AirTAC SAIJ50X650-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 640-650 mm usable travel window, allowing you to dial in the retract end-position precisely during commissioning. Delivering 982 N of push force at 0.5 MPa, it handles mid-range automation tasks with ease.
This model features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this unit is supplied without a magnet. The rear adjuster acts strictly as a travel stop for end-position tuning, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX650-10 Is Used
End-Stop Calibration
Fine-tune the 640-650 mm retract position during machine commissioning to perfectly align tooling without machining new hard stops.
Product Changeover
Quickly adjust the stroke end by up to 10 mm on a packaging line when switching to a slightly different carton size.
Assembly Pressing
Apply 982 N of pressing force at 0.5 MPa while using the rear screw to set the exact depth limit for consistent part insertion.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX650-10 the Right Cylinder?
Choose this 50 mm bore when you need 982 N push force at 0.5 MPa, stepping up from a 40 mm bore (628 N) if your load demands more thrust, or down from a 63 mm bore (1559 N) to save space. The 10 mm adjustable window is perfect for applications requiring minor end-stop corrections without adding external stops or changing the cylinder.
Because the 650 mm stroke is relatively long, ensure adequate external guidance to prevent excessive side-loading on the SUS420J2 rod. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop. To match this ISO 15552 cylinder, specify the 50 mm bore, 650 mm stroke, 10 mm adjust, PT G1/4 port, and your required mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ50 Adjustable Cylinder SAIJ50AX650-10 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
The rear adjuster screw allows you to shorten the nominal 650 mm stroke by up to 10 mm, creating a 640-650 mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without air pressure.
