This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X250TC, 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 SI32X250TC
The AirTAC SI32 Standard Air Cylinder SI32X250TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 250mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X250TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X250TC
The AirTAC SI32X250TC is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 250mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X250TC, which matches the exact TC trunnion mounting interface, output, and dimensions.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. Note this non-magnetic SKU cannot accept a CS1-B/DS1-B sensor.

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 SAI32X250TC 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 SI32X250TC Is Used
Small Parts Ejection
Ideal for pushing lightweight machined components out of a fixture using 402N of force at 0.5 MPa.
Package Diverting
Provides a 250mm reach to sort or divert small cartons on a conveyor line at up to 800 mm/s.
Gripper Actuation
Drives external mechanical grippers for pick-and-place tasks where a 20kg vertical lift margin is sufficient.
Replacing the Airtac SI32 Standard Air Cylinder SI32X250TC with the SAI32X250TC
To replace the SI32X250TC, order the SAI32X250TC. Confirm the ISO 15552 TC trunnion mount, 32mm bore, 250mm stroke, G1/8 port, and M10x1.25 rod thread. Because this SKU lacks the -S magnet, it cannot support position sensing. Sizing both ways: a 40mm bore yields 628N push at 0.5MPa, while dropping pressure to 0.3MPa yields about 241N. For loads needing 250mm of travel, ensure external guidance to prevent rod bending. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X250TC
- ✓ 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 SI32X250TC FAQ
Yes, the SI32X250TC is discontinued. The direct replacement is the SAI32X250TC. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 250mm stroke, TC mount, and G1/8 port.
The G1/8 port feeds thrust of 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a max force of 82kgf at 1.0MPa. Speed is 30-800 mm/s.
