This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X50TC, 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 SI32X50TC
The AirTAC SI32 Standard Air Cylinder SI32X50TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 50mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X50TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X50TC
The AirTAC SI32X50TC is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 50mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X50TC. This direct successor shares the exact TC trunnion mount, M10x1.25 rod thread, and dimensions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. Note this SKU lacks the -S magnet, so it cannot take CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X50TC 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 SAI32X50TC 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 SI32X50TC Is Used
Small Part Ejection
Ideal for pushing lightweight components out of machining fixtures using a compact 50mm stroke and 402N force.
Gate Diverting
Actuates short-travel diverter gates on conveyor lines where a fast 30-800 mm/s cycle and TC trunnion mount are required.
Clamp Actuation
Provides reliable clamping pressure for small pneumatic vises, utilizing its 345N pull force at 0.5 MPa.
Replacing the Airtac SI32 Standard Air Cylinder SI32X50TC with the SAI32X50TC
To replace the SI32X50TC, order the SAI32X50TC. Verify the ISO 15552 TC trunnion mount, 50mm stroke, G1/8 port, and M10x1.25 thread. Because this SKU has no -S magnet, it cannot accept position sensors. For sizing, the 40mm bore offers higher force (628N push @0.5MPa), while the 32mm bore suffices for ~241N loads. Note that a plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X50TC
- ✓ 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 SI32X50TC FAQ
Yes, the SI32X50TC is discontinued. The direct replacement is the SAI32X50TC. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 50mm stroke, G1/8 port, and TC mounting interface.
This double-acting cylinder has a G1/8 port. It delivers 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 force of 82 kgf at 1.0 MPa.
