This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the drop-in replacement SAI32BX560S, 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 SI32BX560S
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX560S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 560mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX560S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX560S
The AirTAC SI32BX560S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore, 560mm stroke, and SUS304 stainless steel rod. Delivering 402N push at 0.5MPa, its exact drop-in replacement is the SAI32BX560S, which matches the G1/8 port, M10x1.25 thread, and mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For your 560mm stroke, expect a safe working load around 241N (roughly 60% of the 0.5MPa push) and a 20kg vertical lift capacity. The original -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL lock, SAIF valve, and BSAI clamp variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX560S 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 SAI32BX560S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32BX560S Is Used
Stainless Rod Actuation
The SUS304 rod resists corrosion in washdown packaging lines, pushing 402N at 0.5MPa over a 560mm travel distance.
Long Stroke Diversion
Uses its 560mm extension to sort parts across wider belts, requiring external guides to prevent rod bending.
Vertical Lift Gates
Lifts light access gates up to 20kg with a 2:1 safety margin, though a pilot check valve is needed to hold position.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX560S with the SAI32BX560S
To replace this SI32BX560S, order the SAI32BX560S to get the identical ISO 15552 interface, 32mm bore, 560mm stroke, G1/8 port, and SUS304 rod. Keep your existing mounting hardware and CS1-B/DS1-B sensors. Because 560mm exceeds 300mm, add external guides to prevent rod bending and side-load wear. If sizing alternatives, a 40mm bore gives 628N push at 0.5MPa. Note that standard cylinders drift on air loss; the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX560S
- ✓ 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 SI32BX560S FAQ
Yes, the SI32BX560S is discontinued. The exact drop-in replacement is the SAI32BX560S. It is dimensionally interchangeable per ISO 15552, keeping the same 32mm bore, 560mm stroke, G1/8 port, and mounting fixtures.
This 32mm bore cylinder features a G1/8 port. It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Operating speed is 30-800mm/s.
