This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X700-75, 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 SIJ63X700-75
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X700-75 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 SAIJ63X700-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-75
The AirTAC SIJ63X700-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63 mm bore and 700 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 625-700 mm end position. As a direct, the SAIJ63X700-75 preserves the exact mounting interface, force, and adjust window.
The SAIJ replacement upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The stop screw sets the end position but is not a load lock; without live air the piston drifts, so use an external rod lock or the SAIL/BSAI variants for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-75 Is Used
Variable Pitch Indexing
Needs field stroke tuning to set precise 625-700 mm extend positions for changing material lengths without swapping the entire actuator.
Adjustable Transfer Pusher
Requires trimming the extend stroke by up to 75 mm on-site to accommodate different package sizes on a dynamic sorting line.
Variable Height Diverter
Demands an adjustable end position to redirect items at varying heights, using the external stop to fine-tune the 700 mm extend.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-75 with the SAIJ63X700-75
To replace this discontinued model, swap directly to the SAIJ63X700-75, keeping the 700 mm nominal stroke and 75 mm adjust window. Choose the 75 mm adjust window if your process requires field-tuning the extend within 625-700 mm. Mounting interfaces (Basic, FA, LB, TC) reuse standard ISO 15552 dimensions. This SKU lacks a -S magnet and cannot take a magnetic switch. For the 700 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X700-75
- ✓ 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 SIJ63X700-75 FAQ
Yes, the SIJ63X700-75 is discontinued. The direct replacement is the SAIJ63X700-75, which matches the 63 mm bore, 700 mm stroke, 75 mm adjust window, G3/8 port, and ISO 15552 mounting interface.
The external stop screw window is 75 mm, allowing the 700 mm extend stroke to be shortened on-site to a minimum of 625 mm.
