This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X200-100STC, 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 SIJ63X200-100STC
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X200-100STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X200-100STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-100STC
The AirTAC SIJ63X200-100STC is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 100-200 mm extension from the 200 mm nominal maximum. The direct replacement is the SAIJ63X200-100STC, matching the interface, force, and TC mount.
The SAIJ successor retains the ISO 15552 mounting interface for direct reuse and incorporates an upgraded SAI piston seal (two Y-shaped one-way elements for low start-up pressure and long life). The stop screw sets the end position but is not a load lock; for held loads use SAIL/BSAI or an external rod lock.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-100STC Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning from 100 to 200 mm for parts requiring different insertion depths without changing the cylinder.
Adjustable Diverter Gate
Sets precise divert distances on the fly using the external stop screw to accommodate varying package widths on the line.
Tiered Push-Out Station
Trims the extend stroke by up to 100 mm to push varied carton sizes from storage racks without repositioning the mount.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-100STC with the SAIJ63X200-100STC
Replace the discontinued SIJ63X200-100STC directly with the SAIJ63X200-100STC, preserving the 200 mm nominal stroke, 100 mm adjust window, and TC mounting interface. Select the 100 mm adjust window when the application requires field tuning between 100 mm and 200 mm extend strokes. The built-in -S magnet supports legacy CS1-B/DS1-B switches. For stroke lengths of 300 mm or greater, verify side-load constraints to prevent rod deflection.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X200-100STC
- ✓ 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 SIJ63X200-100STC FAQ
Yes, the SIJ63X200-100STC is discontinued. The direct replacement is the SAIJ63X200-100STC, offering the same ISO 15552 interface, 63 mm bore, 200 mm stroke, 100 mm adjust window, and G3/8 port.
The external stop screw offers a 100 mm adjust window, shortening the extend stroke from 200 mm to 100 mm. The stop sets end position and is not a load lock.
