This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X160STC, 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 SI32X160STC
The AirTAC SI32 Standard Air Cylinder SI32X160STC 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 SAI32X160STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X160STC
The AirTAC SI32X160STC is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 160mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X160STC, matching the exact TC trunnion mount, M10x1.25 rod thread and output force.
Upgrading to the SAI32X160STC introduces an improved piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SAI family also adds SAIL, SAIF and BSAI lock variants absent from the SI line. The -S magnet works with legacy CS1-B/DS1-B sensors.

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 SI32X160STC Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight machined components out of a fixture on an automated line.
Package Diverting
Actuates a routing gate along a conveyor belt, taking advantage of the 160mm stroke and TC trunnion mount for smooth pivoting.
Bin Sorting
Provides the physical push needed to divert small totes into sorting lanes without overpowering the lightweight containers.
Replacing the Airtac SI32 Standard Air Cylinder SI32X160STC with the SAI32X160STC
To replace the SI32X160STC, order the SAI32X160STC. Verify the ISO 15552 TC trunnion mounting interface, 32mm bore, 160mm stroke, G1/8 port and the -S magnet for CS1-B/DS1-B switches. If you need more force, the adjacent 40mm bore yields 628N push at 0.5MPa; if less is acceptable, check smaller custom options. A plain cylinder drifts on air loss as the cushion only decelerates, so for load holding consider an external pilot check valve or the SAIL lock variant. At 160mm stroke, rod bending stress is low, but ensure side loads are minimized with proper guide rails.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X160STC
- ✓ 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 SI32X160STC FAQ
Yes, the SI32X160STC is discontinued. The direct replacement is the AirTAC SAI32X160STC. It features the same ISO 15552 mounting interface, 32mm bore, 160mm stroke, G1/8 port and TC mount, fitting existing fixtures perfectly.
The 32mm bore delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Operating speed is 30-800 mm/s. It uses a G1/8 port and has a 27mm adjustable air cushion at each end.
