This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32BX160, 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 SI32BX160
The AirTAC SI32 Standard Air Cylinder SI32BX160 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 SAI32BX160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX160
The AirTAC SI32BX160 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 Delivering 402N push force at 0.5MPa via a G1/8 port, it is superseded by the SAI32BX160. This direct replacement shares the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting hardware, fitting existing fixtures perfectly.
The SAI upgrade features a refined piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also introduces SAIL, SAIF and BSAI variants absent from the SI line. Note this SKU uses a SUS304 stainless rod (-B) but lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX160 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 | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32BX160 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32BX160 Is Used
Compact Clamping
Ideal for securing small machined components during milling, providing reliable 402N hold at 0.5MPa without overwhelming delicate fixtures.
Stainless Rod Ejection
The SUS304 piston rod excels in ejecting small plastic or brass parts from humid moulds, resisting corrosion where a standard carbon rod would pit.
Light Diverter Actuation
Provides accurate 160mm travel for pivoting lightweight conveyor sorting gates, smoothly redirecting small packaged goods at high speeds.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX160 with the SAI32BX160
To replace the SI32BX160, order the SAI32BX160. Confirm the ISO 15552 interface, 32mm bore, 160mm stroke, G1/8 port (PT/G/NPT thread options) and mounting accessory. This SKU has a SUS304 stainless rod (-B) but no magnet (-S), meaning it cannot support CS1-B/DS1-B switches. Sizing both ways: neighbouring bores (40mm) yield 628N push at 0.5MPa, while dropping to 25mm lowers force. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 160mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX160
- ✓ 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 SI32BX160 FAQ
Yes, the SI32BX160 is discontinued. The direct replacement is the SAI32BX160. It is a true ISO 15552 profile cylinder with the same 32mm bore, 160mm stroke, 402N force, G1/8 port and mounting interface, fitting existing fixtures directly.
This 32mm bore cylinder uses a G1/8 port. Force ratings are: 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 features a 12mm SUS304 rod and 27mm adjustable cushions.
