This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X700-75S, 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 SIJ63X700-75S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X700-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X700-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-75S
The AirTAC SIJ63X700-75S 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 75 mm on-site, giving a usable 625-700 mm stroke window. The direct replacement is the SAIJ63X700-75S, matching the ISO 15552 interface, force, and mounting.
The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. The stop screw sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-75S Is Used
Variable Depth Boring
Needs field stroke tuning to set precise boring depths on-site without swapping cylinders, using the 75 mm adjust window.
Adjustable Transfer Pusher
Requires altering the extend endpoint to handle changing package sizes, trimming the stroke from 700 mm down to 625 mm.
Variable Height Diverting
Demands precise end-position adjustment for diverting items at varying heights while maintaining ISO 15552 mounting.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-75S with the SAIJ63X700-75S
To replace the discontinued SIJ63X700-75S, order the direct replacement SAIJ63X700-75S, keeping the 63 mm bore, 700 mm nominal stroke, 75 mm adjust window, G3/8 port, and -S magnet for CS1-B/DS1-B switches. Choose the 75 mm adjust window if you need significant on-site extend trimming down to 625 mm. Reuse FA, LB, or TC ISO 15552 mounts. Because the 700 mm stroke is long, ensure external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X700-75S
- ✓ 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 SIJ63X700-75S FAQ
Yes, the SIJ63X700-75S is discontinued. The direct replacement is the SAIJ63X700-75S, offering the same 63 mm bore, 700 mm stroke, 75 mm adjust window, G3/8 port, and ISO 15552 mounting interface.
The external stop screw allows trimming the extend stroke by up to 75 mm on-site, yielding a 625-700 mm usable stroke window.
