This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X30H, 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 SI32X30H
The AirTAC SI32 Standard Air Cylinder SI32X30H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 30mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X30H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X30H
The AirTAC SI32X30H is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 30 mm stroke. It delivers 402 N push force at 0.5 MPa, features a G1/8 port, and includes a high-temperature Viton H seal rated for 0 to 150 C. Because this unit lacks a magnet (-S), it cannot accept position sensors.
The direct replacement is the SAI32X30H. It shares the exact ISO 15552 mounting interface, force, and port size, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SI32 Standard Air Cylinder SI32X30H Is Used
High-Temp Ejection
Short 30 mm strokes eject small parts from heated molds using the Viton H seal to withstand 150 C ambient temperatures.
Compact Clamping
Clamps small workpieces in tight machining fixtures where the 32 mm bore provides sufficient 402 N force without excess bulk.
Valve Actuation
Pilots or switches mechanical valves in thermal processing equipment, relying on the 12 mm rod for precise 30 mm movements.
Replacing the Airtac SI32 Standard Air Cylinder SI32X30H with the SAI32X30H
To replace the SI32X30H, order the SAI32X30H and verify your ISO 15552 mounting fixtures, G1/8 port, and M10x1.25 rod thread. This high-temp Viton H variant suits environments up to 150 C. Since this SKU lacks a magnet, it cannot support CS1-B or DS1-B sensors; if sensing is needed, select an -S magnet model. For sizing alternatives, the neighboring 40 mm bore yields 628 N push at 0.5 MPa. Remember that a standard cylinder does not hold load without live air; the 27 mm cushions only decelerate. For secure holding, use an external pilot check valve or explore the SAIL lock and SAIF integrated valve variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X30H
- ✓ 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 SI32X30H FAQ
Yes, the SI32X30H is discontinued. The direct replacement is the SAI32X30H, which shares the same ISO 15552 mounting interface, 32 mm bore, 30 mm stroke, G1/8 port, and Viton H high-temp seal.
It uses a G1/8 port. The force output is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa.
