This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X180S, 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 SI32X180S
The AirTAC SI32 Standard Air Cylinder SI32X180S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 180mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X180S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X180S
The AirTAC SI32X180S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 180mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X180S, matching the exact bore, stroke, force, port and ISO 15552 mounting interface for seamless fixture integration.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SAI family also introduces SAIL, SAIF and BSAI lock variants absent from the SI line.

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 SI32X180S 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 diverter arm with its 180mm stroke to route small boxes on a conveyor, benefiting from the 30-800mm/s speed range.
Replacing the Airtac SI32 Standard Air Cylinder SI32X180S with the SAI32X180S
To replace the SI32X180S, order the SAI32X180S keeping the 32mm bore, 180mm stroke, G1/8 port, M10x1.25 rod thread and -S magnet for CS1-B/DS1-B switches. Confirm your ISO 15552 mounting accessory (LB, FA, TC) and thread standard (PT, G, NPT). For higher force, the 40mm bore yields 628N push at 0.5MPa; for less space, the 32mm is the smallest option. A plain cylinder drifts on air loss as cushions only decelerate; use an external pilot check valve or the SAIL lock variant to hold loads. At 180mm stroke, side-load is minimal but ensure front rod alignment to prevent seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X180S
- ✓ 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 SI32X180S FAQ
Yes, the SI32X180S is discontinued. The direct replacement is the AirTAC SAI32X180S. It shares the same ISO 15552 mounting interface, 32mm bore, 180mm stroke, output force, G1/8 port and accessories, fitting directly into existing fixtures.
This 32mm bore double-acting cylinder features a G1/8 air port. It provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum force of 82kgf at 1.0MPa.
