This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X300SN, 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 SI32 Standard Air Cylinder SI32X300SN
The AirTAC SI32 Standard Air Cylinder SI32X300SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X300SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X300SN
The AirTAC SI32X300SN is a discontinued double-acting ISO 15552 profile cylinder featuring a 32mm bore, 300mm stroke, and a G1/8 port. Delivering 402N push force at 0.5MPa, it is replaced by the SAI32X300SN. This direct successor matches the exact interface, force, and mounting hardware.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. It also adds SAIL, SAIF, and BSAI variants absent from the SI line. For your NBR seal needs, note the Viton H option raises operating limits to 150C. Your -S magnet supports CS1-B/DS1-B switches, while the SAI uses current sensors.

Where the Airtac SI32 Standard Air Cylinder SI32X300SN Is Used
Compact Part Ejection
Uses the 402N push force to eject small molded components from a fixture, fitting neatly into tight machinery footprints via the 32mm profile barrel.
Light Package Diverting
Actuates a diverter arm over a 300mm reach to sort lightweight packages on a line, benefiting from the 30-800mm/s speed range for rapid cycling.
Small Component Pressing
Provides steady 20kg vertical pressing force for seating bearings or pins, relying on the adjustable 27mm air cushions to soften end-of-stroke impact.
Replacing the Airtac SI32 Standard Air Cylinder SI32X300SN with the SAI32X300SN
To replace the SI32X300SN, order the SAI32X300SN. Confirm the ISO 15552 mounting interface, 32mm bore, 300mm stroke, G1/8 port, and your NBR seal choice. Because this is a 300mm stroke, use external guides to prevent rod bending and side-load damage. For sizing, the 40mm neighbor bore offers 628N push at 0.5MPa if more force is needed. Remember, a plain cylinder drifts without live air; the cushion only decelerates. For load holding, use an external pilot check valve or explore the SAIL lock and BSAI clamp-lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X300SN
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI32 Standard Air Cylinder SI32X300SN FAQ
Yes, the SI32X300SN is discontinued. The direct replacement is the SAI32X300SN. It is dimensionally interchangeable per ISO 15552, keeping the same 32mm bore, 300mm stroke, 402N force, G1/8 port, and mounting fixtures.
The 32mm bore features a G1/8 port. At 0.5MPa it provides 402N push and 345N pull force. At 0.7MPa push is 563N, and 724N at 0.9MPa. The theoretical maximum force is 82kgf at 1.0MPa.
