This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X50SH, 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 SI32X50SH
The AirTAC SI32 Standard Air Cylinder SI32X50SH 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 SAI32X50SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X50SH
The AirTAC SI32X50SH is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 50mm stroke. It delivers 402N push force at 0.5MPa and features a G1/8 port. The direct replacement is the SAI32X50SH, matching the exact mounting interface, force, and dimensions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The SAI family also adds SAIL and BSAI lock 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 | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32X50SH 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 SI32X50SH Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using the 402N push force at 0.5MPa.
Gate Diversion
Actuates small routing flaps or gates on a conveyor line with a responsive 30-800mm/s speed range.
Material Transfer
Moves small electronic parts between stations with a 50mm stroke and 20kg safe vertical lift capacity.
Replacing the Airtac SI32 Standard Air Cylinder SI32X50SH with the SAI32X50SH
To replace this SI32X50SH, order the SAI32X50SH direct. Confirm the ISO 15552 mounting interface, 32mm bore, 50mm stroke, G1/8 port, and the -S magnet for CS1-B/DS1-B switches. The SAI uses current AirTAC switches. Sizing both ways: if you need more force, the neighbouring 40mm bore gives 628N push at 0.5MPa. For high-temperature environments, specify the -H Viton seal (0-150 C). Remember, 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 → SAI32X50SH
- ✓ 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 SI32X50SH FAQ
Yes, the SI32X50SH is discontinued. The direct replacement is the SAI32X50SH. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 50mm stroke, 402N force, G1/8 port, and mounting interface.
This 32mm bore double-acting cylinder has a G1/8 port. The thrust is 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum of 82kgf at 1.0MPa.
