This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X10, 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 SI32X10
The AirTAC SI32 Standard Air Cylinder SI32X10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 10mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X10
The AirTAC SI32X10 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 10 mm stroke, delivering 402 N push force at 0.5 MPa. AirTAC replaced it with the SAI32X10, a direct upgrade sharing the exact ISO 15552 mounting interface, G1/8 port, and M10x1.25 rod thread. This SKU lacks a magnet (-S), so it cannot accept a CS1-B or DS1-B sensor.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X10 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 SAI32X10 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 SI32X10 Is Used
Short-Stroke Clamping
Ideal for compact 32 mm bore clamping tasks where a 10 mm stroke quickly secures lightweight machined parts during milling.
Ejector Mechanism
Provides a fast 402 N push at 0.5 MPa to eject small plastic or aluminum components from a mold cavity.
Diverting Gate
Drives small pneumatic diverters on a conveyor belt, using the 10 mm stroke to shift product flow between lanes.
Replacing the Airtac SI32 Standard Air Cylinder SI32X10 with the SAI32X10
To replace this SI32X10, order the SAI32X10. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G1/8 port, and note this non-magnetic SKU cannot hold a switch. If you need more force, the neighboring 40 mm bore yields 628 N push at 0.5 MPa; if less force is acceptable, check smaller non-ISO alternatives. Remember, a standard cylinder drifts without live air—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL lock variant. At this 10 mm stroke, side-load risks are minimal, but always guide the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X10
- ✓ 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 SI32X10 FAQ
Yes, the AirTAC SI32X10 is discontinued. The direct replacement is the SAI32X10. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 32 mm bore, 10 mm stroke, G1/8 port, and output force.
This 32 mm bore double-acting cylinder features a G1/8 port and M10x1.25 rod thread. It delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa.
