This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X80SCA, 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 SI32X80SCA
The AirTAC SI32 Standard Air Cylinder SI32X80SCA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X80SCA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X80SCA
The AirTAC SI32X80SCA is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke and a 32 mm bore. It delivers 402 N of push force at 0.5 MPa through a G1/8 port. AirTAC replaced this unit with the SAI32X80SCA, a direct upgrade retaining the exact ISO 15552 mounting interface, CA clevis, and output force.
The SAI successor features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The family also adds SAIL, SAIF, and BSAI lock variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X80SCA 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 | — |

Where the Airtac SI32 Standard Air Cylinder SI32X80SCA Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using the 402 N push force at 0.5 MPa.
Package Diverting
Provides reliable actuation for a 80 mm stroke diverting arm on a compact packaging line.
Clamp Actuation
Secures small workpieces during secondary machining operations with a 20 kg safe vertical lift capacity.
Replacing the Airtac SI32 Standard Air Cylinder SI32X80SCA with the SAI32X80SCA
To replace the SI32X80SCA, order the SAI32X80SCA. Verify your ISO 15552 CA clevis mounting, 32 mm bore, 80 mm stroke, G1/8 port, and the -S magnet for CS1-B/DS1-B sensors. If you need more force, the neighboring 40 mm bore yields 628 N push at 0.5 MPa; if less is acceptable, check smaller profiles. Remember that a plain cylinder drifts on air loss, as the cushion only decelerates. For load holding, consider an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X80SCA
- ✓ 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 SI32X80SCA FAQ
Yes, the SI32X80SCA is discontinued. The direct replacement is the SAI32X80SCA. It shares the identical ISO 15552 mounting interface, 32 mm bore, 80 mm stroke, G1/8 port, and CA clevis, fitting directly into existing fixtures.
This double-acting cylinder uses a G1/8 port. It generates 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa.
