This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X200N, 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 SI32X200N
The AirTAC SI32 Standard Air Cylinder SI32X200N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 200mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X200N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X200N
The AirTAC SI32X200N is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 200mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X200N. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting accessories.
The SAI successor features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This SKU lacks a magnet, so it cannot accept a CS1-B/DS1-B sensor. The NBR seal handles -20 to +70C, though Viton H raises this to 150C.

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 SI32X200N Is Used
Small Part Ejection
Ideal for pushing light machined components out of a fixture using its 402N push force at 0.5 MPa.
Package Diverting
Actuates routing gates on a 32mm bore assembly line to redirect small boxes at 30-800 mm/s.
Clamp Actuation
Provides reliable clamping pressure for lightweight material holding in automated welding cells.
Replacing the Airtac SI32 Standard Air Cylinder SI32X200N with the SAI32X200N
To replace the SI32X200N, order the SAI32X200N, confirming the ISO 15552 interface, 32mm bore, 200mm stroke, G1/8 port (PT/G/NPT thread options) and mounting accessory. Because this SKU lacks an -S magnet, it cannot support position sensing. If you need more force, the neighbouring 40mm bore provides 628N push at 0.5MPa. Note that a plain cylinder drifts on air loss; the air cushion only decelerates near stroke end. For load holding, use an external pilot check valve or explore the SAIL (air-released lock) or BSAI (clamp-lock) variants. The SAIF variant integrates a 4M valve for bores 32-100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X200N
- ✓ 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 SI32X200N FAQ
Yes, the SI32X200N is discontinued. The direct replacement is the SAI32X200N. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 200mm stroke, 402N force, G1/8 port and mounting interface.
The 32mm bore uses a G1/8 port. Force output is 402N push and 345N pull at 0.5 MPa, 563N push at 0.7 MPa, 724N push at 0.9 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa.
