This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X80-100S, 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 SIJ63X80-100S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X80-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 80mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X80-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X80-100S
The AirTAC SIJ63X80-100S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63 mm bore and 80 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 0-80 mm window. The stop sets the end position but is not a load lock.
The direct replacement is the SAIJ63X80-100S, reusing your ISO 15552 mounts, force, and adjust window. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The -S suffix means a piston magnet is present for CS1-B/DS1-B switches.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X80-100S Is Used
Custom End-Position Clamping
Ideal for production lines where a clamp must contact varying material thicknesses, using the stop screw to tune the exact extend position without reprogramming the PLC.
Variable-Length Diverting
Perfect for diverting packages of differing sizes on a belt, allowing operators to manually shorten the actuator reach on-site to match specific product dimensions.
Prototype Tooling Setup
Highly useful in prototype tooling where the final stroke dimension is unknown, letting engineers dial in the precise movement during initial machine commissioning.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X80-100S with the SAIJ63X80-100S
To replace this discontinued model, order SAIJ63X80-100S, inserting an A after the leading S; the ISO 15552 interface, 80 mm stroke, 100 mm adjust window, and G3/8 port are identical. Choose the 100 mm adjust window when you need aggressive on-site end-position tuning. Mounting options include FA, LB, and TC. The -S suffix confirms the piston magnet is present for legacy CS1-B/DS1-B switches. For stroke lengths of 300 mm or greater, verify your side-load limits to prevent excessive rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X80-100S
- ✓ 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 SIJ63X80-100S FAQ
Yes, the SIJ63X80-100S is discontinued. The direct replacement is the SAIJ63X80-100S. It shares the same ISO 15552 mounting interface, 63 mm bore, 80 mm stroke, 100 mm adjust window, and G3/8 port, but adds an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw provides a 100 mm adjustment window, allowing you to trim the 80 mm nominal extend stroke down to 0 mm on-site. The stop sets end position and is not a load lock.
