About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-10S
The AirTAC SAIJ63X220-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2182 N push force at 0.7 MPa, making it well-suited for mid-range automation tasks. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves.
This specific SKU provides a 220 mm nominal stroke that can be fine-tuned down by up to 10 mm, yielding a precise 210-220 mm usable travel window. It features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel design ensures it is dimensionally interchangeable with ISO 15552 cylinders without being a tie-rod type.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-10S Is Used
Machine Setup Tuning
Dial in the exact 210-220 mm travel window during commissioning to perfect end-positioning without swapping cylinders.
Product Changeover
Quickly adjust the rear stop to accommodate slight variations in product dimensions on a packaging line.
Mid-Force Positioning
Leverage the 2182 N push force at 0.7 MPa to move and position moderate loads accurately.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-10S the Right Cylinder?
Choose this 63 mm bore when you need higher force than a 50 mm bore (which provides 1374 N push at 0.7 MPa), but do not require the bulk of an 80 mm option. The 10 mm rear adjuster is ideal for dialing in exact end positions during commissioning or product changeovers without adding external stops. If you need to hold a load without live air pressure, note that this adjuster acts only as a travel stop; you should look at the SAIL or BSAI locking series instead. To replace an ISO 15552 cylinder, match the 63 mm bore, 220 mm stroke, 10 mm adjustment, G3/8 PT ports, and the -S magnet requirement. For this 220 mm stroke, ensure external guides support any heavy lateral loads.
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 SAIJ63AX220-10S FAQ
At 0.7 MPa operating pressure, this 63 mm bore cylinder generates a push force of 2182 N and a pull force of 1402 N. It can reach a maximum push force of 2805 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel by up to 10 mm from the 220 mm nominal stroke, providing a 210-220 mm usable window. This stopper fine-tunes the end position but does not lock the load without live air pressure.
