This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X160, 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 SI32X160
The AirTAC SI32 Standard Air Cylinder SI32X160 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 SAI32X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X160
The AirTAC SI32X160 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 160mm stroke. Delivering 402N push force at 0.5MPa, it is replaced by the SAI32X160. This direct upgrade keeps the same G1/8 port, M10x1.25 thread, and mounting interface.
The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure. This SKU lacks a magnet, so it cannot take a sensor. For high heat, Viton H seals raise the limit to 150C.

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 SI32X160 Is Used
Package Diverting
Provides reliable 160mm stroke actuation to push small cartons off a production line, operating efficiently at 30-800 mm/s.
Light Assembly Pressing
Delivers 402N of push force at 0.5MPa to seat bearings or pins into housings gently and accurately on automated fixtures.
Replacing the Airtac SI32 Standard Air Cylinder SI32X160 with the SAI32X160
To replace the SI32X160, order the SAI32X160. Confirm the ISO 15552 mounting accessory (LB, FA, TC) and the G1/8 port. Since this SKU has no -S magnet, it cannot accept CS1-B/DS1-B sensors. For sizing, a 40mm bore offers 628N push at 0.5MPa if more force is needed. At 160mm stroke, guide rods prevent side-load bending. The plain cylinder drifts on air loss; use SAIL or BSAI lock variants, or a pilot check valve to hold loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X160
- ✓ 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 SI32X160 FAQ
Yes, the SI32X160 is discontinued. The direct replacement is the SAI32X160. It shares the same ISO 15552 mounting interface, 32mm bore, 160mm stroke, output force, G1/8 port, and accessories, fitting directly into existing fixtures.
The bore is 32mm with a G1/8 port. Force output is 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a maximum theoretical force of 82kgf at 1.0MPa. It operates at 30-800 mm/s.
