This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X1000-50, 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-50
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X1000-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-50
The AirTAC SIJ80X1000-50 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 1000 mm nominal stroke and a G3/8 port. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 950-1000 mm window.
The direct replacement is the SAIJ80X1000-50, matching the bore, force, adjust window, and mounting. The SAIJ family uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure. Note this SKU lacks a magnet (-S) for sensing, and the stop screw sets end position but is not a load lock.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-50 Is Used
Material Discharge Diverter
Adjusts the extend stop on-site to tune the diverter gate position for varying package sizes on a conveyor line without re-mounting the actuator.
Multi-Part Clamping Press
Trims the extend stroke by up to 50 mm to accommodate different workpiece heights, ensuring precise clamping force without repositioning the cylinder.
Variable Depth Pallet Stops
Fine-tunes the physical stop position for pallets of varying depths, allowing on-site adjustment of the extend end point within the 950-1000 mm range.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-50 with the SAIJ80X1000-50
To replace the discontinued SIJ80X1000-50, order the direct replacement SAIJ80X1000-50, keeping the exact 80 mm bore, 1000 mm nominal stroke, 50 mm adjust window, and G3/8 port. Choose the 50 mm adjust window if you need to fine-tune the extend end position by up to 50 mm on-site. Mounting interfaces include Basic, FA, LB, and TC. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch for position sensing. For the 1000 mm long stroke, use external guides to prevent rod bending and manage side loads. The stop screw sets the end position but does not hold the load on air loss; for load holding, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X1000-50
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-50 FAQ
Yes, the SIJ80X1000-50 is discontinued. The direct replacement is the SAIJ80X1000-50, which matches the ISO 15552 interface, 80 mm bore, 1000 mm stroke, 50 mm adjust window, and G3/8 port. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for lower start-up pressure.
The external stop screw window is 50 mm, allowing you to shorten the 1000 mm extend stroke down to 950 mm on-site. The stop sets end position only; it is not a load lock.
