This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X300-100S, 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 SIJ80X300-100S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X300-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 300mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X300-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X300-100S
The AirTAC SIJ80X300-100S is a discontinued double-acting double-rod adjustable-stroke ISO 15552 cylinder. An external stop screw lets you trim the extend stroke by up to 100mm on-site, giving a usable 200-300mm extension from the 300mm nominal maximum. It features a 25mm rod, M20x1.5 thread, 36mm adjustable cushions, and a G3/8 port. The direct replacement is the SAIJ80X300-100S, retaining the same interface, force, and mounting.
The SAIJ upgrade utilizes an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B sensors. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X300-100S Is Used
Variable Depth Forming Press
Requires field stroke tuning to alter the extend reach by up to 100mm for different material thicknesses without changing the cylinder.
Adjustable Transfer Pusher
Needs on-site stroke trimming to push varying package sizes accurately, utilizing the 200-300mm usable extend window.
Multi-Position Divert Gate
Demands an external stop screw to set precise end positions for sorting items into different lanes on the fly.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X300-100S with the SAIJ80X300-100S
To replace the discontinued SIJ80X300-100S, order the direct replacement SAIJ80X300-100S, which preserves the 80mm bore, 300mm nominal stroke, 100mm adjust window, G3/8 port, and ISO 15552 mounting. Choose the 100mm adjust window if your application requires trimming the extend stroke anywhere from 200mm to 300mm on-site. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix confirms the piston magnet is present for switch sensing. Because the stroke is 300mm, ensure external guides support side loads to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X300-100S
- ✓ 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 SIJ80X300-100S FAQ
Yes, the SIJ80X300-100S is discontinued. The direct replacement is the SAIJ80X300-100S. It shares the identical ISO 15552 interface, 80mm bore, 300mm stroke, 100mm adjust window, G3/8 port, and mounting options, but adds an upgraded piston seal.
The external stop screw window is 100mm, allowing you to shorten the 300mm nominal extend stroke down to 200mm on-site. Note that this stop sets end position and is not a load lock.
