This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X600LB, 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 SI32X600LB
The AirTAC SI32 Standard Air Cylinder SI32X600LB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 600mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X600LB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X600LB
The AirTAC SI32X600LB is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 600mm stroke. It delivers 402N push at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X600LB, matching the interface, force, and LB foot mount exactly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This no-S SKU lacks a magnet and cannot take a sensor; legacy CS1-B/DS1-B switches only fit the -S version.

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 SI32X600LB Is Used
Light-Part Ejection
Pushes light plastic or cardboard parts off a conveyor belt over the 600mm travel distance.
Package Diverting
Acts as a diverter arm in a packaging line, moving small cartons between processing lanes.
Fixture Actuation
Opens and closes secondary clamping fixtures on an automated assembly station.
Replacing the Airtac SI32 Standard Air Cylinder SI32X600LB with the SAI32X600LB
To replace the SI32X600LB, order the SAI32X600LB and confirm the ISO 15552 interface, 32mm bore, 600mm stroke, G1/8 port, and LB foot mounting accessory. Because this is a 600mm stroke, use an external guide to prevent rod bending and side-load wear. If sizing alternatives, neighboring bores offer different forces, but at 0.5MPa this 32mm bore pushes 402N and pulls 345N. Note that a plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X600LB
- ✓ 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 SI32X600LB FAQ
Yes, the SI32X600LB is discontinued. The direct replacement is the SAI32X600LB. It shares the same ISO 15552 mounting interface, 32mm bore, 600mm stroke, output force, G1/8 port, and LB foot mount, fitting existing fixtures perfectly.
This double-acting cylinder has a G1/8 port and M10x1.25 rod thread. It generates 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. Operating speed is 30-800mm/s.
