This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X170, 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 SI32X170
The AirTAC SI32 Standard Air Cylinder SI32X170 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 170mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X170, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X170
The AirTAC SI32X170 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 170 mm stroke. Delivering 402 N push force at 0.5 MPa, it features a 12 mm carbon steel rod, M10x1.25 thread, and a G1/8 port. The direct replacement is the SAI32X170, which shares the exact ISO 15552 mounting interface, output force, and dimensions.
This SAI upgrade introduces an improved piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. Because this specific SI32X170 SKU lacks the -S magnet suffix, it cannot accept position sensors. For load-holding, note that standard cylinders drift without live air; use an external pilot check valve or the SAIL lock variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X170 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 SAI32X170 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 SI32X170 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push lightweight molded plastic parts out of a machining fixture.
Package Diverting
Actuates a routing gate on a packaging line, where the 170 mm stroke provides just enough travel to redirect small cartons.
Clamp Actuation
Drives a low-force secondary clamp to hold thin sheet metal stock in place during a light stamping operation.
Replacing the Airtac SI32 Standard Air Cylinder SI32X170 with the SAI32X170
To replace the SI32X170, order the SAI32X170. Confirm the ISO 15552 mounting interface (LB, FA, or TC), the 170 mm stroke, and the G1/8 port. Because this SKU has no -S suffix, it cannot support CS1-B or DS1-B sensors; if sensing is needed, order the -S magnet version. Sizing both ways: this 32 mm bore yields 402 N push at 0.5 MPa; if less force is acceptable, a smaller bore works, but for higher loads step up to a 40 mm bore (628 N). For stroke lengths at or above 300 mm, add external guide rails to prevent rod bending under side loads. If the application requires load holding on air loss, select the SAIL or BSAI lock variant instead of relying on the 27 mm adjustable air cushion, which only decelerates the piston.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X170
- ✓ 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 SI32X170 FAQ
Yes, the SI32X170 is discontinued. The direct replacement is the AirTAC SAI32X170. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 170 mm stroke, G1/8 port, and mounting interface.
The SI32X170 has a G1/8 port. It generates 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. Operating speed is 30-800 mm/s.
