This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X400-10S, 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 SIJ80X400-10S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 400mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X400-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-10S
The AirTAC SIJ80X400-10S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 390-400 mm stroke. The 80 mm bore features a Ø25 mm rod, M20x1.5 thread, G3/8 port, and 36 mm adjustable cushions. The direct replacement is the SAIJ80X400-10S, sharing the same interface, force, and port.
The SAIJ upgrade uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The stop sets end position but is NOT a load lock; use SAIL or BSAI for held loads. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B sensors.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-10S Is Used
Press Fit Tuning
Trimming the 400 mm extend stroke by up to 10 mm on-site allows precise contact positioning for pressing bearings without machining hard stops.
Divertor Gate Adjustment
Field-tuning the extend end position by 10 mm adapts a diverting gate to varying package sizes on the fly using the G3/8 ported actuator.
Pallet Stop Positioning
The external stop screw provides a 390-400 mm stroke window to fine-tune pallet end-stops, ensuring exact alignment for downstream wrappers.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-10S with the SAIJ80X400-10S
To replace the discontinued SIJ80X400-10S, use the direct replacement SAIJ80X400-10S. Mounting options include FA, LB, and TC. The -S magnet enables position sensing. For the 400 mm stroke, support side-load and rod-bending with external guides to prevent premature wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X400-10S
- ✓ 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 SIJ80X400-10S FAQ
Yes, the SIJ80X400-10S is discontinued. The direct replacement is the SAIJ80X400-10S, which shares the identical ISO 15552 interface, 80 mm bore, 400 mm stroke, 10 mm adjust window, G3/8 port, and mounting options. The SAIJ features an upgraded piston seal for longer life.
The external stop screw provides a 10 mm adjust window (usable extend 390-400 mm). It uses a G3/8 port, runs at 30-800 mm/s, and the stop sets end position but is NOT a load lock.
