This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X300SH, 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 SI32X300SH
The AirTAC SI32 Standard Air Cylinder SI32X300SH 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 SAI32X300SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X300SH
The AirTAC SI32X300SH is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 300mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, its direct replacement is the SAI32X300SH, matching the exact mounting interface and output.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This -S -H variant includes a piston magnet for CS1-B/DS1-B sensors and a Viton H seal rated for 0-150C.

Where the Airtac SI32 Standard Air Cylinder SI32X300SH Is Used
Package Diverting
Provides reliable 300mm stroke actuation to divert small cartons on a high-speed packaging line.
High-Temp Testing
The Viton H seal accommodates 0-150C environments, making it suitable for thermal cycling test chambers.
Replacing the Airtac SI32 Standard Air Cylinder SI32X300SH with the SAI32X300SH
To replace the SI32X300SH, order the SAI32X300SH, confirming the ISO 15552 interface, 32mm bore, 300mm stroke, G1/8 port, and mounting accessories. The -S magnet and -H Viton seal must be specified. At 0.5MPa it yields 402N push and 345N pull; if more force is needed, step up to a 40mm bore (628N push). For this 300mm stroke, use external guides to prevent rod bending and side-load wear. Note that standard cylinders drift on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X300SH
- ✓ 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 SI32X300SH FAQ
Yes, the SI32X300SH is discontinued. The direct replacement is the SAI32X300SH, which shares the same ISO 15552 mounting interface, 32mm bore, 300mm stroke, output force, and G1/8 port.
This double-acting cylinder features a G1/8 port and delivers a push force of 402N and pull force of 345N at 0.5MPa. At 0.7MPa push is 563N, 724N at 0.9MPa, with a theoretical max of 82kgf at 1.0MPa.
