This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X183, 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 SI32X183
The AirTAC SI32 Standard Air Cylinder SI32X183 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 183mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X183, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X183
The AirTAC SI32X183 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 183 mm stroke, delivering 402 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI32X183. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force, G1/8 port and accessories, fitting existing fixtures perfectly.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this nonstandard 183 mm stroke SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors. For load holding, the cushion only decelerates; use an external rod lock or SAIL/BSAI variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X183 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 SAI32X183 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 SI32X183 Is Used
Compact Clamping
Provides reliable 402 N clamping force at 0.5 MPa for holding thin material profiles in assembly jigs.
Replacing the Airtac SI32 Standard Air Cylinder SI32X183 with the SAI32X183
To replace the discontinued SI32X183, order the SAI32X183 direct. Confirm the ISO 15552 mounting interface (LB, FA, CA, TC, etc.), the 32 mm bore, the 183 mm nonstandard stroke, the G1/8 port, and your thread option (PT, G, or NPT). Since this SKU lacks the -S magnet, it cannot support position sensing; if you need switches, select an SAI32X183S and use current AirTAC sensors. For sizing both ways: neighboring bores offer different forces (40 mm gives 628 N push @0.5 MPa), and at 0.7 MPa this 32 mm bore pushes 563 N. Because the 183 mm stroke is nonstandard and approaches 300 mm, ensure your guiding mechanism handles side loads to prevent rod bending. A plain cylinder drifts without live air; for load holding, specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X183
- ✓ 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 SI32X183 FAQ
Yes, the AirTAC SI32X183 is discontinued. The direct replacement is the SAI32X183. It is a true ISO 15552 profile cylinder that matches the original 32 mm bore, 183 mm stroke, force, G1/8 port, and mounting interface, dropping directly into existing fixtures.
This 32 mm bore double-acting cylinder uses a G1/8 air port. At 0.5 MPa it pushes 402 N and pulls 345 N. At 0.7 MPa it pushes 563 N, and at 0.9 MPa it pushes 724 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
