About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-10
The AirTAC SAIJ63X150-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 140 to 150 mm, allowing you to dial back the extension by up to 10 mm during commissioning. Delivering 1559 N of push thrust at 0.5 MPa, it handles robust actuation tasks while using a G3/8 port for efficient airflow.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear stopper mechanism lets you fine-tune the end position without swapping out the entire cylinder or adding external stops.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-10 Is Used
End-Position Tuning
Dial in the exact 140 to 150 mm extension point during machine commissioning to perfect product placement without external shims.
Product Changeover
Quickly adjust the stroke by up to 10 mm on a packaging line when switching to a slightly shorter package format.
Assembly Pressing
Apply up to 1559 N of force at 0.5 MPa for pressing components, using the rear screw to fine-tune the exact crush depth.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-10 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is too weak but an 80 mm bore (2513 N) would be excessive. The 10 mm adjustment range is ideal for applications requiring precise end-position tuning during machine setup or product changeover, rather than using a fixed-stroke SAI cylinder. For holding loads without live air pressure, note that this rear adjuster acts only as a travel stop and does not function as a lock; consider the SAIL or BSAI series for load-holding requirements.
To match this ISO 15552 cylinder, specify a 63 mm bore, 150 mm stroke, 10 mm adjustment, G3/8 PT ports, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Since the 150 mm stroke is moderate, side-load stress is minimal, but always guide long unsupported rods to prevent binding.
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 SAIJ63AX150-10 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 1.0 MPa pressure, it can deliver up to 318 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 150 mm down to 140 mm. This allows precise end-position tuning at commissioning without replacing the cylinder.
