About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-100S
The AirTAC SAIJ63X220-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 220 mm stroke that can be dialed back by up to 100 mm, yielding a highly flexible 120-220 mm usable travel window. Delivering 1559 N of pull force at 0.5 MPa, it handles robust actuation while allowing precise end-position tuning during commissioning without swapping out the unit.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for position sensing. It is compatible with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves of the extruded aluminum barrel. The integrated rear stopper sets the retraction end-point, though it acts strictly as a travel stop and does not lock the load without continuous live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-100S Is Used
Product Changeovers
Ideal for packaging lines running multiple carton sizes, utilizing the 120-220 mm adjustable window to rapidly reconfigure retraction distances without changing hardware.
End-Stop Calibration
Allows maintenance teams to micro-adjust the retract position during machine setup, compensating for mechanical wear or sensor drift without adding external stopper blocks.
Variable Pitch Indexing
Provides a adaptable stroke length for automated assembly stations that must handle varying part pitches on a single shared conveyor line.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-100S the Right Cylinder?
Choose this 63 mm bore cylinder when an application requires variable end-stops or frequent product-size changeovers, stepping up from a 50 mm bore (which provides 825 N pull at 0.5 MPa) to gain necessary thrust. The generous 100 mm adjustment window allows operators to fine-tune the retraction point on the fly, avoiding the need to bolt on external stops or purchase multiple fixed-stroke SAI cylinders. Because the 220 mm stroke exceeds 300 mm is not the case here, a side-load guide is less critical than on longer strokes, but the 20 mm rod diameter and M16x1.5 thread still provide a rigid interface that benefits from external guidance if subjected to lateral forces.
When specifying a replacement, verify the 63 mm bore, 220 mm nominal stroke, 100 mm adjustment range, PT tapered port threads, and the -S magnet option. Remember that the rear adjuster and air cushions only decelerate the stroke; they do not function as a brake. For applications requiring true load-holding without live air, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. Mounting options for this series include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ63AX220-100S 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 its maximum rated pressure of 1.0 MPa, it can deliver up to 318 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke from its 220 mm nominal length. With the 100 mm adjustment code, you can set the actual travel anywhere within a 120 to 220 mm window, though it functions as a stop and does not lock the load without air pressure.
