This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X900-10S, 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 SIJ80X900-10S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 900mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X900-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-10S
The AirTAC SIJ80X900-10S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder. A 900mm nominal extend is shortened on-site by an external stop screw, letting you trim the extend stroke by up to 10mm for a usable 890-900mm window. The stop screw sets end position; it is not a load lock.
This SIJ model is discontinued; the direct replacement is the SAIJ80X900-10S, reusing the exact ISO 15552 mounting interface. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure. Note: a plain cylinder drifts on air loss; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-10S Is Used
Press Tonnage Calibration
Needs field stroke tuning to precisely set the 890-900mm extend endpoint, ensuring accurate contact pressure during assembly operations.
Divertor Gate Adjustment
Requires trimming the extend stroke by up to 10mm on-site to perfectly align a routing flap without repositioning the ISO 15552 mounts.
Pallet Stop Positioning
Demands adjustable end-position tuning to accommodate varying pallet depths, using the stop screw to fine-tune the 900mm extend limit.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-10S with the SAIJ80X900-10S
To replace the discontinued SIJ80X900-10S, use the SAIJ80X900-10S directly—same 80mm bore, 900mm stroke, 10mm adjust window, and G3/8 port. The 10mm adjust window is ideal for final positional tuning. Mounting options include FA, LB, and TC brackets. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches. Because the 900mm stroke exceeds 300mm, support the rod against side-load bending and use external guides. The stop screw sets end position but does not lock the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X900-10S
- ✓ 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 SIJ80X900-10S FAQ
Yes, the SIJ80X900-10S is discontinued. The direct replacement is the SAIJ80X900-10S. It shares the same ISO 15552 interface, 80mm bore, 900mm stroke, 10mm adjust window, G3/8 port, and mounting options, but uses an upgraded two Y-shaped one-way piston seal.
The theoretical max is 513kgf at 1.0MPa. The external stop screw provides a 10mm adjustable window, allowing the 900mm extend stroke to be shortened to 890mm on-site. The stop sets end position and is not a load lock.
