About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX210-10S
The AirTAC SAIJ63X210-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 200 to 210 mm, allowing you to dial back the nominal 210 mm stroke by up to 10 mm during commissioning. In the 63 mm bore class, it delivers 1559 N of pull force at 0.5 MPa and 2182 N of push force at 0.7 MPa, making it well-suited for mid-range actuation tasks.
This unit features a SUS420J2 stainless steel piston rod for enhanced durability against side loads, paired with a G3/8 PT tapered port. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports position detection via CMSE reed or DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX210-10S Is Used
End-Position Tuning
Dial in the exact 200 to 210 mm retract distance during machine setup to perfect product ejection without changing hardware.
Product Changeover
Quickly adapt the stroke window on a packaging line when switching to a slightly different carton size.
Clamp Positioning
Fine-tune the clamping end-stop on a machining fixture to accommodate varying part tolerances safely.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX210-10S the Right Cylinder?
Choose this 63 mm bore model when your application requires a 200-210 mm stroke window and approximately 1559 N of pull force at 0.5 MPa. If you need less force, the 50 mm bore offers 825 N of pull; if you need more, the 80 mm bore provides 2268 N. The adjustable-stroke design is ideal for setups requiring precise end-position tuning without swapping cylinders or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is a travel stop, not a lock. Since the 210 mm stroke is under 300 mm, side-load risks are moderate, but an external guide is still recommended for heavy lateral loads. This cylinder is dimensionally interchangeable per ISO 15552 and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.

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 SAIJ63AX210-10S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, providing a usable travel window of 200 to 210 mm. It acts as a mechanical stop to fine-tune the end position and works alongside the adjustable air cushions, but it does not lock or hold the load without live air pressure.
At 0.5 MPa, the 63 mm bore provides 1559 N of pull force and 1402 N of push force. At 0.7 MPa, the push force increases to 2182 N. The maximum operating pressure is 1.0 MPa.
