This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X200, 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 SI32X200
The AirTAC SI32 Standard Air Cylinder SI32X200 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 SAI32X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X200
The AirTAC SI32X200 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 200mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. Because this legacy unit lacks a -S magnet, it cannot accept a position sensor.
Order the direct replacement SAI32X200, which shares the exact ISO 15552 mounting interface, bore, stroke, force and port. The SAI features an upgraded piston seal (two Y-shaped one-way elements for low start-up pressure) and adds SAIL, SAIF and BSAI variants the SI lacked.

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 SI32X200 Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using the 402N thrust at 0.5 MPa.
Package Diverting
Actuates a diverting gate or routing flap on a 24V conveyor line with a 200mm travel distance.
Clamp Actuation
Provides reliable clamping pressure for holding thin sheet metal or plastic housings during light assembly.
Replacing the Airtac SI32 Standard Air Cylinder SI32X200 with the SAI32X200
To replace this SI32X200, order the SAI32X200 keeping the identical 32mm bore, 200mm stroke, G1/8 port and ISO 15552 mounting. Confirm your thread standard (PT/G/NPT) and mounting accessory (LB, FA, TC, etc.). This plain non-magnet SKU cannot take a sensor; if you need position detection, select an SAI32X200S and use current AirTAC switches. Note: a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant. At 200mm stroke, rod bending is minimal, but for strokes >=300mm, guide external loads to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X200
- ✓ 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 SI32X200 FAQ
Yes, the SI32X200 is discontinued. The direct replacement is the SAI32X200. It shares the same ISO 15552 mounting interface, 32mm bore, 200mm stroke, output force and G1/8 port, fitting existing fixtures perfectly.
This double-acting cylinder has a G1/8 air port. It generates 402N push and 345N pull at 0.5 MPa, 563N push at 0.7 MPa, 724N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa.
