This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X800-10S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X800-10S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X800-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 800mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X800-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X800-10S
The AirTAC SIJ63X800-10S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ63X800-10S. It uses an external stop screw to trim the extend stroke by up to 10mm on-site, giving a usable 790-800mm stroke from the 800mm nominal maximum. The SAIJ direct keeps the interface, force, and M16x1.5 rod thread.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The stop screw sets end position but is not a lock; loads drift on air loss, so use an external rod lock or SAIL/BSAI variant. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X800-10S Is Used
Press Fit Tuning
Field-tune the 10mm extend stop to set precise pressing depths for bearing insertion without re-mounting the actuator.
Transfer Diverter
Adjust the extend end position on-site to accommodate varying package sizes on a sorting line.
Pallet Stop Gate
Fine-tune the 800mm extend stroke to act as a physical stop for different pallet widths entering a wrap station.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X800-10S with the SAIJ63X800-10S
To replace the discontinued SIJ63X800-10S, map directly to the SAIJ63X800-10S direct, retaining the 63mm bore, 800mm max stroke, 10mm adjust window, and G3/8 port. Choose the 10mm adjust window for fine-tuning the extend end position. Mounting options include FA, LB, and TC brackets. The -S magnet supports legacy CS1-B/DS1-B sensors. At 800mm stroke, mind side-load and rod-bending forces; use external guides to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X800-10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X800-10S FAQ
