This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X200-20S, 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 SIJ63X200-20S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X200-20S 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 SAIJ63X200-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-20S
The AirTAC SIJ63X200-20S 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 20 mm on-site, giving a usable 180-200 mm extend window from the 200 mm nominal maximum. The direct replacement is the SAIJ63X200-20S, matching the interface, bore, force, and mounts.
The stop screw sets the end position but is not a load lock; without live air the piston drifts. For held loads use an external rod lock or SAIL/BSAI variant. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B sensors.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-20S Is Used
Press Fit Tuning
Needs field stroke tuning to dial in the exact 180-200 mm extend position for seating bearings without bottoming out the tooling.
Transfer Diverter
Requires adjustable end-positioning to alter the extend reach on-site as product widths change on the handling line.
Carton Forming Stop
Needs field stroke tuning to precisely set the forming head extension for varying package depths.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-20S with the SAIJ63X200-20S
To replace the discontinued SIJ63X200-20S, map directly to the SAIJ63X200-20S direct, reusing your existing ISO 15552 FA, LB, or TC mounts. Choose the 20 mm adjust window if you only need minor 180-200 mm extend tuning; for larger trims select a 30+ mm window. Retain the -S magnet for position sensing. For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X200-20S
- ✓ 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 SIJ63X200-20S FAQ
Yes, the SIJ63X200-20S is discontinued. The direct replacement is the SAIJ63X200-20S. It shares the identical ISO 15552 interface, 63 mm bore, 200 mm stroke, 20 mm adjust window, G3/8 port, and mounting options, but features an upgraded two Y-shaped one-way piston seal.
The external stop screw window is 20 mm, allowing you to trim the extend stroke from 200 mm down to 180 mm. The stop sets end position and does not lock the load.
