This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X16CB, 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 SI32X16CB
The AirTAC SI32 Standard Air Cylinder SI32X16CB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 16mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X16CB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X16CB
The AirTAC SI32X16CB is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 16mm stroke, delivering 402N push force at 0.5MPa. It is directly replaced by the SAI32X16CB direct, sharing identical CB clevis mounting, G1/8 port, and stroke. This SKU lacks a magnet, so it cannot accept a sensor.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life, plus SAIL lock and BSAI clamp-lock variants the SI lacked. Remember, the cushion only decelerates; use a pilot check valve to hold loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X16CB 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 SAI32X16CB 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 SI32X16CB Is Used
Compact Ejector
Short 16mm stroke pushes small parts out of machining fixtures using 402N of force.
Clamp Actuator
Applies quick clamping pressure on light assemblies where a 20kg vertical lift margin is sufficient.
Gate Diverter
Handles small package routing stops with a compact 32mm bore and G1/8 air supply.
Replacing the Airtac SI32 Standard Air Cylinder SI32X16CB with the SAI32X16CB
To replace this SI32X16CB with the SAI32X16CB, verify the ISO 15552 CB clevis mount, 32mm bore, 16mm stroke, and G1/8 port. Because this specific SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B switches. If sensing is required, order the SAI equivalent with an S suffix. For sizing, neighboring bores like 40mm offer 628N push at 0.5MPa if more force is needed, while staying at 32mm keeps the compact footprint. Note that a plain cylinder drifts without live air; for load holding, consider the SAIL lock variant or an external pilot check valve. Rod material options include carbon steel or SUS304.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X16CB
- ✓ 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 SI32X16CB FAQ
Yes, the SI32X16CB is discontinued. The direct replacement is the SAI32X16CB. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 16mm stroke, CB clevis mount, and G1/8 port, so it fits existing fixtures directly.
The 32mm bore uses a G1/8 port. Force output is 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. The rod is 12mm with an M10x1.25 thread.
