About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-10S
The AirTAC SAIJ63X150-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 150 mm stroke that can be dialed back by up to 10 mm, creating a precise 140-150 mm usable travel window for fine-tuning end positions at commissioning. Delivering 1559 N of push force and 1402 N of pull force at 0.5 MPa, it is built to handle robust industrial actuation.
This variant features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting, while the rear adjuster acts purely as a travel stop and does not lock the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-10S Is Used
End-Position Tuning
Dial in the exact 140-150 mm retract position during machine commissioning to compensate for mechanical wear or sensor variance without hardware changes.
Product Changeover
Quickly adjust the stroke end-stop by up to 10 mm on a packaging line when switching to a slightly different product size, saving downtime.
Assembly Actuation
Provides 1559 N of push force at 0.5 MPa for pressing or clamping components, with a magnet for DMSE sensors to confirm stroke completion.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-10S the Right Cylinder?
Choose this 63 mm bore when you need higher thrust than a 50 mm cylinder (982 N push at 0.5 MPa) but want to avoid the larger footprint of an 80 mm bore (2513 N push). The 10 mm rear adjustment screw allows you to dial in the exact retract end-position during machine setup or product changeover without swapping the cylinder or adding external stops. If your application requires the load to be held mechanically without continuous air pressure, you must integrate an external rod lock or pilot-operated check valve, as the SAIJ adjuster is a stop, not a locking device.
For ISO 15552 replacement matching, specify a 63 mm bore, 150 mm stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts. Because the 150 mm stroke is below the 300 mm threshold, side-load stress on the M16x1.5 rod thread is minimal, though external guidance is still recommended for heavy lateral loads.
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 SAIJ63AX150-10S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder generates 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 acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm, providing a usable travel window of 140 to 150 mm. It only decelerates and sets the travel end; it does not lock or hold the load without live air pressure.
