About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-10
The AirTAC SAIJ63X220-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 1559 N of push force at 0.5 MPa. Its 220 mm nominal stroke incorporates a 10 mm adjustment range, yielding a precise 210-220 mm usable travel window for fine-tuning the retract end position. This built-in stopper allows you to dial in the exact endpoint during commissioning without adding external physical stops.
This bore features a 20 mm carbon steel rod upgraded to SUS420J2 stainless steel (code A) for improved corrosion resistance, paired with a G3/8 port and M16x1.5 rod thread. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, adding an -S variant enables compatibility with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-10 Is Used
Commissioning Calibration
Dial in the exact 210-220 mm retract position during machine setup, using the rear screw to fine-tune the endpoint without swapping out the entire cylinder.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on packaging lines when handling slightly different product sizes, ensuring precise physical positioning.
Machining Clamping
Provides 1559 N of clamping thrust at 0.5 MPa, with the rear stopper allowing minute adjustments to the clamping depth without external mechanical stops.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-10 the Right Cylinder?
Select this 63 mm bore cylinder when you need 1559 N push (1402 N pull) at 0.5 MPa, stepping up from a 50 mm bore (982 N push) or down from an 80 mm bore (2513 N push). The 10 mm rear adjuster acts purely as a travel stop for end-position tuning, not a lock; it cannot hold a load without live air. For load-holding requirements without continuous pneumatic pressure, consider an AirTAC SAIL pneumatic lock, BSAI clamp-lock cylinder, or an external rod lock. This profile cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Confirm your port thread (PT tapered) and mounting style when ordering.
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 SAIJ63AX220-10 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 220 mm nominal stroke by up to 10 mm, creating a 210-220 mm usable travel window. It functions as an end-position stop, not a lock, meaning it cannot hold the load without live air pressure.
