About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-30S
The AirTAC SAIJ63X220-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 190-220 mm usable travel window, allowing you to dial back the 220 mm nominal stroke by up to 30 mm. Operating at 0.7 MPa, it delivers 2182 N of push force and 1962 N of pull force, placing it in a robust force class suitable for medium-duty automation.
This specific configuration features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and includes a magnet for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and the unit relies on adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-30S Is Used
Changeover Tuning
Dial in the exact 190-220 mm end-stop during machine format changes without replacing the entire cylinder assembly.
Assembly Pressing
Delivers precise 2182 N of thrust at 0.7 MPa for pressing components, with the rear screw allowing micro-adjustments for different part heights.
Sensor Positioning
The integrated magnet triggers CMSE or DMSE sensors along the dual-side grooves to confirm end-of-stroke arrival for the control system.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-30S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) lacks the thrust for your assembly task, but an 80 mm bore (2513 N push at 0.5 MPa) would be physically oversized. The 30 mm rear adjuster is ideal for fine-tuning the end position during commissioning or product changeover without swapping the cylinder or adding external stops. Remember that the rear adjuster and air cushions act as travel stops and deceleration devices, not a lock; if you need to hold a load without live air pressure, consider an AirTAC SAIL or BSAI cylinder. As an ISO 15552 interchangeable cylinder, it uses a PT G3/8 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. Because the 220 mm stroke is substantial, ensure external guides are used to prevent excessive side-load on the M16x1.5 rod thread.
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 SAIJ63AX220-30S FAQ
At 0.7 MPa, this 63 mm bore cylinder provides 2182 N of push force and 1962 N of pull force. Its operational speed range is 30-800 mm/s, adjustable via the integrated air cushions at both ends.
The rear adjuster screw lets you shorten the 220 mm nominal stroke by up to 30 mm, creating a 190-220 mm usable travel window. This allows you to fine-tune the retract end position during setup without adding external mechanical stops.
