This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X300, 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 SI32X300
The AirTAC SI32 Standard Air Cylinder SI32X300 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X300, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X300
The AirTAC SI32X300 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 300mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. AirTAC replaced this legacy unit with the SAI32X300, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, and output force.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this SKU lacks a magnet (-S) and cannot accept a CS1-B/DS1-B sensor. For high-heat environments, Viton H seals raise the operating range to 0-150C.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X300 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 SAI32X300 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 SI32X300 Is Used
Small Parts Ejection
Uses the 402N push force at 0.5MPa to reliably eject small machined components from a fixture without damaging the surface.
Package Diverting
Extends 300mm to actuate a routing gate on a packaging line, operating efficiently at speeds between 30-800 mm/s.
Replacing the Airtac SI32 Standard Air Cylinder SI32X300 with the SAI32X300
To replace the SI32X300, order the SAI32X300 with the identical M10x1.25 rod thread, G1/8 port, and ISO 15552 mounting accessory (LB, FA, TC, etc.). Confirm your thread standard (PT, G, or NPT) and rod material (carbon, SUS420J2, or SUS304). Because this 300mm stroke is relatively long for a 32mm bore, use an external guide to prevent rod bending and side-load wear. If sizing up, a 40mm bore yields 628N push at 0.5MPa; if sizing down, custom strokes are available. This non-magnetic SKU cannot host a sensor. For load holding on air loss, add an external pilot check valve or explore the SAIL lock or BSAI clamp-lock variants, as cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X300
- ✓ 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 SI32X300 FAQ
Yes, the SI32X300 is discontinued. The direct replacement is the AirTAC SAI32X300. It features the same ISO 15552 mounting interface, 32mm bore, 300mm stroke, output force, and G1/8 port, fitting existing fixtures perfectly.
The bore is 32mm with a G1/8 air port. It generates 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. The speed range is 30-800 mm/s.
