About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-40
The AirTAC SAIJ63X150-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 110 to 150 mm, allowing you to dial in the retract end-position precisely during commissioning without swapping out the unit. Built with a 63 mm bore, it delivers a robust 1559 N push force at 0.5 MPa, making it well-suited for moderate industrial handling tasks.
This specific SKU is configured with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, PT tapered port threads, and operates without a piston magnet. The rear adjuster acts purely as a mechanical stop to set the travel limit, while the standard variable air cushions handle end-of-stroke deceleration. It shares the exact extruded aluminum barrel and sensor grooves of the fixed-stroke SAI series.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-40 Is Used
Machine Changeover
Quickly fine-tune the 110-150 mm travel window during product size changes without replacing the cylinder or adding external stops.
End-Position Calibration
Dial in the exact retract distance at commissioning to perfect part ejection or clamping depth on automated machinery.
Assembly Line Timing
Adjust the stroke on the fly to sync cylinder movement with varying component sizes on a dynamic production line.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-40 the Right Cylinder?
Select this 63 mm bore cylinder when your application requires 1559 N of push force at 0.5 MPa, stepping up from a 50 mm bore (982 N) if you need extra thrust, or down from an 80 mm bore (2513 N) to save space. The 40 mm adjustment window is ideal for product changeovers on a line where exact end-positioning varies, avoiding the need to physically swap cylinders or bolt on external stops. To match this exact configuration for an ISO 15552 replacement, ensure you specify the 150 mm stroke, PT ports, the 40 mm adjustment range, and no magnet.
Because the nominal stroke is 150 mm, side-loading is less of a concern, but always ensure the load is guided to prevent binding. Note that the rear adjuster and air cushions do not hold the load without live air pressure; if your setup requires true load-holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead.
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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-40 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At the maximum pressure of 1.0 MPa, it can deliver up to 318 kgf.
The rear adjuster screw allows you to mechanically shorten the effective stroke by up to 40 mm. This creates a usable travel window of 110 to 150 mm, letting you set the exact retract end-position during setup without changing the cylinder.
