This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X8, 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 SI32X8
The AirTAC SI32 Standard Air Cylinder SI32X8 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 8mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X8, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X8
The AirTAC SI32X8 is a discontinued double-acting ISO 15552 profile cylinder. Delivering 402 N push force at 0.5 MPa through a 32 mm bore and 8 mm stroke, it features a G1/8 port and M10x1.25 rod thread. The direct is the SAI32X8, matching the exact interface, force, and mounting.
The SAI32X8 upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Since this specific SI SKU lacks the -S magnet, it cannot accept a CS1-B/DS1-B sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X8 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32X8 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32X8 Is Used
Short-Stroke Clamping
Ideal for applying precise 402 N clamping force on small machined parts within tight fixture clearances.
Ejector Mechanisms
Provides rapid 8 mm ejection of lightweight components from automated assembly tooling at speed.
Gate Diverting
Handles low-force diverting duties on small material handling lines where a compact footprint is required.
Replacing the Airtac SI32 Standard Air Cylinder SI32X8 with the SAI32X8
To replace the SI32X8, order the SAI32X8 keeping the identical 32 mm bore, 8 mm stroke, G1/8 port, and ISO 15552 mounting. Confirm your thread option (PT, G, or NPT) and accessory type (LB, FA, FB, CA, CB, TC). Because this SKU has no -S magnet, it cannot host a sensor; if position detection is needed, select an SAI32X8S. For higher force, neighbouring bores like the 40 mm offer 628 N push at 0.5 MPa. Note that a plain cylinder drifts on air loss; for load holding, specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X8
- ✓ 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 SI32X8 FAQ
Yes, the SI32X8 is discontinued. The direct replacement is the SAI32X8. It is dimensionally interchangeable per ISO 15552, maintaining the same 32 mm bore, 8 mm stroke, 402 N force, G1/8 port, and mounting interface.
The 32 mm bore uses a G1/8 port. Force output is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The cylinder operates at 30-800 mm/s.
