This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1330S, 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 SI80 Standard Air Cylinder SI80X1330S
The AirTAC SI80 Standard Air Cylinder SI80X1330S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1330mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1330S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1330S
The AirTAC SI80X1330S is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel, delivering 2513 N push force at 0.5 MPa through its G3/8 port. Because this legacy SI unit is end-of-life, AirTAC supplies the SAI80X1330S as the direct replacement. It matches the original 80 mm bore, 1330 mm stroke, M20x1.5 rod thread, and ISO 15552 mounting interface.
The SAI upgrade introduces a refined piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also expands functionality with SAIL air-released lock, SAIF integrated valve, and BSAI clamp-lock variants that the original SI line lacked. Your existing CS1-B/DS1-B sensors will mount to the magnet groove, though current AirTAC switches are recommended for the replacement.

Where the Airtac SI80 Standard Air Cylinder SI80X1330S Is Used
Long-Stroke Material Transfer
Drives heavy pallets across extended conveyor sections where the 1330 mm travel and 2513 N push force at 0.5 MPa are required to shift loads between machining centers.
Large Assembly Fixture Actuation
Indexing heavy automotive or industrial sub-assemblies over a 1330 mm span, utilizing the adjustable 36 mm air cushions to decelerate moving mass at stroke ends.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1330S with the SAI80X1330S
To replace the discontinued SI80X1330S, order the SAI80X1330S direct equivalent, verifying your ISO 15552 mounting accessories (LB, FA, CA, TC), the G3/8 port thread, and the -S magnet requirement. This 1330 mm stroke exceeds standard mid-range lengths, so an external guide is strongly recommended to prevent rod bending and excessive side loading. If you need to size both ways, the neighboring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore provides 5497 N. A plain cylinder does not hold load without live air; the cushions only decelerate. For load holding on air loss, use an external pilot check valve, a rod lock, or specify the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1330S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI80 Standard Air Cylinder SI80X1330S FAQ
Yes, the SI80X1330S is discontinued. The direct replacement is the AirTAC SAI80X1330S. It features the same ISO 15552 mounting interface, 80 mm bore, 1330 mm stroke, output force, and G3/8 port, fitting directly into existing fixtures.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-800 mm/s, and it uses a G3/8 port with a 25 mm rod.
