This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X35H, 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 SI32X35H
The AirTAC SI32 Standard Air Cylinder SI32X35H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 35mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X35H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X35H
The AirTAC SI32X35H is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 35 mm stroke. It delivers 402 N push force at 0.5 MPa and uses a G1/8 port. The direct replacement is the SAI32X35H, which shares the exact ISO 15552 mounting interface, bore, stroke, output force, and port size for seamless fixture integration. This specific SKU features a Viton H seal for high-temperature environments up to 150 C.
Because this non-magnetic SKU lacks a -S suffix, it cannot accept a position sensor. The SAI upgrade introduces an advanced piston seal with two Y-shaped one-way elements for low start-up pressure and extended life.

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 SI32X35H Is Used
Small Part Clamping
Ideal for securing compact housings or electronics during machining, utilizing the 402 N push force at 0.5 MPa for firm, non-distorting grip.
High-Temperature Ejection
The Viton H seal accommodates up to 150 C, making it suitable for ejecting molded components near heat sources where standard NBR seals would fail.
Short-Stroke Sorting
The 35 mm stroke provides rapid diversion of lightweight items on packaging lines without occupying excessive machine footprint.
Replacing the Airtac SI32 Standard Air Cylinder SI32X35H with the SAI32X35H
To replace the discontinued SI32X35H, order the SAI32X35H. Confirm the ISO 15552 mounting interface, 32 mm bore, 35 mm stroke, G1/8 port (PT/G/NPT thread), and your specific mounting accessory. This SKU has no magnet, so it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, select an SAI model with an S suffix. The 35 mm stroke is short and avoids rod-bending side-load issues, but if you need more force, the neighboring 40 mm bore offers 628 N push at 0.5 MPa. A plain cylinder does not hold load on air loss; for load holding, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X35H
- ✓ 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 SI32X35H FAQ
Yes, the AirTAC SI32X35H is discontinued. The direct replacement is the SAI32X35H. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 35 mm stroke, G1/8 port, and mounting interface.
This double-acting cylinder uses a G1/8 port. It delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa.
