This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X215S, 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 SI80X215S
The AirTAC SI80 Standard Air Cylinder SI80X215S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 215mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X215S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X215S
The AirTAC SI80X215S is a discontinued double-acting ISO 15552 profile cylinder with a 215 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X215S, matching the exact bore, stroke, force, port, and ISO 15552 mounting interface for seamless fixture integration.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI variants the SI lacked. The -S suffix provides a piston magnet for CS1-B/DS1-B switches.

Where the Airtac SI80 Standard Air Cylinder SI80X215S Is Used
Heavy-Duty Pressing
Drives actuators and stamping heads requiring 2513 N thrust at 0.5 MPa, utilizing the 215 mm stroke to clear tooling before the press cycle.
Pallet Diversion
Pushes heavy loaded pallets off a main conveyor line, with the nonstandard 215 mm stroke ensuring full extension into the transfer zone.
Material Lift Stops
Acts as a robust physical stop for descending loads or lifts, safely decelerating moving masses using the adjustable 36 mm air cushions.
Replacing the Airtac SI80 Standard Air Cylinder SI80X215S with the SAI80X215S
To replace the SI80X215S, order the SAI80X215S and confirm the ISO 15552 mounting interface, G3/8 port, and M20x1.5 rod thread. Because 215 mm exceeds the 200 mm standard increment, it is a nonstandard stroke; ensure your SAI supplier can manufacture this exact length. If you need to size up or down, neighboring bores are 63 mm (1559 N push @0.5 MPa) and 100 mm (3927 N push @0.5 MPa). For stroke lengths over 300 mm, use a guide to prevent rod bending and side loads. A plain cylinder drifts on air loss; the 36 mm adjustable cushion only decelerates. For load holding, specify an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X215S
- ✓ 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 SI80X215S FAQ
Yes, the AirTAC SI80X215S is discontinued. The direct replacement is the SAI80X215S. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 215 mm stroke, output force, G3/8 port, and mounting accessories.
This double-acting cylinder features a G3/8 port and an M20x1.5 rod. It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
