This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X160CA, 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 SI32X160CA
The AirTAC SI32 Standard Air Cylinder SI32X160CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 160mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X160CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X160CA
The AirTAC SI32X160CA is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 160mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the direct replacement SAI32X160CA, which shares the exact CA clevis mounting and dimensions. This non-magnet SKU cannot accept a sensor.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. If you need load holding on air loss, the plain SAI drifts, so consider the SAIL lock or BSAI clamp-lock variants.

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 SI32X160CA Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight molded parts out of an injection molding fixture.
Package Diverting
Actuates a short 160mm stroke diverter arm on a packaging line to route small cartons at speeds up to 800mm/s.
Clamp Actuation
Secures small workpieces in a machining cell via the ISO 15552 CA clevis mount, handling a safe 241N working load.
Replacing the Airtac SI32 Standard Air Cylinder SI32X160CA with the SAI32X160CA
To replace the SI32X160CA, order the SAI32X160CA. Confirm the ISO 15552 CA clevis interface, 32mm bore, 160mm stroke, and G1/8 port (PT/G/NPT thread options). This SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors. Sizing both ways: a 40mm bore offers 628N push at 0.5MPa, while dropping to 25mm stroke keeps the same force. At 160mm stroke, side-load is low, but always guide the rod to prevent bending. The air cushion only decelerates; it does not hold the load. For static holding without air, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X160CA
- ✓ 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 SI32X160CA FAQ
Yes, the SI32X160CA is discontinued. The direct replacement is the SAI32X160CA. It is a true ISO 15552 profile cylinder that matches the 32mm bore, 160mm stroke, 402N force, G1/8 port, and CA clevis mounting interface, fitting directly into existing fixtures.
This 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 max of 82kgf at 1.0MPa. It operates at 30-800mm/s.
