About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX20-10S
The AirTAC SAIJ63X20-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 1559N push force at 0.5 MPa and features a 10 to 20 mm usable travel window, allowing you to dial in the exact retract distance during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific configuration incorporates an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and ships with a magnet (-S) compatible with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered ports and, like all SAIJ models, supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX20-10S Is Used
Short-Stroke Clamping
Dial in the exact clamping depth on delicate parts using the 10-20 mm travel window to prevent crushing during machine setup.
Product Changeover
Quickly adjust the retract end-stop by up to 10 mm to accommodate slight variations in product height without changing cylinders.
Compact Assembly Stations
Fit precise actuation into tight spaces where a standard 20 mm stroke needs minor mechanical trimming at commissioning.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX20-10S the Right Cylinder?
Select this 63 mm bore cylinder when an application requires precise end-position tuning within a very short travel distance. The 10 mm adjustment range lets you fine-tune the retract stop without adding external shims or swapping the cylinder, which is ideal for compact machine setups. If your force requirements are lower, stepping down to a 50 mm bore yields 982N push force at 0.5 MPa.
When matching this adjustable cylinder to a fixed-stroke ISO 15552 replacement, verify the 20 mm nominal stroke, 10 mm adjuster, PT port thread, and the required mounting style. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ63AX20-10S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559N of push force and 1402N of pull force. It can reach a maximum push force of 2805N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 20 mm nominal stroke by up to 10 mm, creating a 10 to 20 mm usable travel window. The adjuster functions as a mechanical stop and does not lock the load without continuous air pressure.
