About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX10-10
The AirTAC SAIJ63X10-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 10 mm nominal stroke that can be dialed back by up to 10 mm, yielding a 0-10 mm usable travel window for exact end-position tuning. Delivering 1559 N of push force at 0.5 MPa, it handles robust actuation tasks.
This variant incorporates a SUS420J2 stainless steel rod for enhanced durability against surface wear and utilizes PT tapered port threads for reliable sealing. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX10-10 Is Used
Short-Stroke Clamping
Provides precise 0-10 mm travel tuning for clamping parts with varying thicknesses on a single fixture.
Commissioning Calibration
Allows operators to dial in the exact retract end-stop during machine setup without swapping out the entire cylinder.
Product Changeover
Ideal for packaging lines that require rapid adjustment of the stroke end when switching between different product sizes.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX10-10 the Right Cylinder?
Select this 63 mm bore cylinder when an application requires 1559 N of push force at 0.5 MPa and exacting short-stroke control. If your process demands less force, the 50 mm bore offers 982 N; for heavier loads, the 80 mm bore provides 2513 N. The rear adjuster screw acts as a travel stop to fine-tune the end position during commissioning without adding external stops.
For load-holding without live air pressure, this cylinder is insufficient as the adjuster and air cushions only decelerate travel; consider an AirTAC SAIL or BSAI series. This configuration features a PT port thread, a SUS420J2 rod, no magnet, and a 10 mm adjustment range, making it dimensionally interchangeable per ISO 15552.
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 SAIJ63AX10-10 FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. It can reach up to 2805 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm. This creates a 0-10 mm usable travel window for fine-tuning the end position without replacing the cylinder.
