This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ200X75-30, 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 SIJ200 Double Rod Adjustable Cylinder SIJ200X75-30
The AirTAC SIJ200 Double Rod Adjustable Cylinder SIJ200X75-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ200X75-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-30
The AirTAC SIJ200X75-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 200 mm bore and 75 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable extend range of 45-75 mm. The stop sets the end position; it is not a load lock.
The direct replacement is the SAIJ200X75-30, retaining the same ISO 15552 mounting interface, bore, stroke, adjust window, and force. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch; for load holding on air loss, use an external rod lock or SAIL/BSAI variant, as the cushion only decelerates.

Where the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-30 Is Used
Heavy Press Tonnage Tuning
Adjust the 30 mm extend window on-site to set precise contact pressure for large 200 mm bore pressing tasks without re-mounting the cylinder.
Oversize Payload Diverter
Trim the extend stroke by up to 30 mm in the field to accommodate varying package widths on a heavy-duty sorting conveyor line.
Industrial Lift Positioning
Fine-tune the end stop for heavy vertical lifting rigs where exact top-end positioning must be calibrated after mechanical installation.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-30 with the SAIJ200X75-30
To replace the discontinued SIJ200X75-30, specify the SAIJ200X75-30 direct, keeping the 75 mm nominal stroke and 30 mm adjust window (45-75 mm usable extend). Reuse existing FA, LB, or TC ISO 15552 mounts. This SKU lacks the -S magnet and cannot accept a sensor. For strokes of 300 mm or longer, verify side-load guidance to prevent rod distortion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X75-30
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-30 FAQ
Yes, the SIJ200X75-30 is discontinued. The direct replacement is the SAIJ200X75-30, which shares the same ISO 15552 interface, 200 mm bore, 75 mm stroke, 30 mm adjust window, G3/4 port, and mounting options.
The external stop screw provides a 30 mm adjust window, shortening the 75 mm nominal extend stroke down to 45 mm. The stop sets end position and is not a load lock.
