This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X600SLB, 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 SI32X600SLB
The AirTAC SI32 Standard Air Cylinder SI32X600SLB 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 SAI32X600SLB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X600SLB
The AirTAC SI32X600SLB is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 600 mm stroke. It delivers 402 N push force at 0.5 MPa via a G1/8 port. AirTAC replaced this legacy unit with the SAI32X600SLB, a direct upgrade retaining the exact interface, force, and LB mounting.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI variants the SI lacked. The -S magnet works with CS1-B/DS1-B sensors, while a Viton H seal option raises heat resistance to 150 C.

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 SI32X600SLB Is Used
Light-Part Ejection
Pushes small molded components off a conveyor belt over a 600 mm span using 402 N of thrust.
Carton Diverting
Actuates a diverting arm in packaging lines where a 20 kg vertical lift margin is sufficient.
Fixture Clearing
Retracts a clamping fixture clear of the machining area using the LB foot mount and long stroke.
Replacing the Airtac SI32 Standard Air Cylinder SI32X600SLB with the SAI32X600SLB
To replace the SI32X600SLB, order the SAI32X600SLB. Confirm the ISO 15552 mounting interface, 32 mm bore, 600 mm stroke, G1/8 port, and LB foot bracket. The -S magnet enables CS1-B/DS1-B sensors. Sizing both ways: a 40 mm bore yields 628 N push at 0.5 MPa, while dropping to 25 mm stroke keeps the same 402 N force. Because stroke is 600 mm, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts without air; for load holding, use an external rod lock, pilot check valve, or the SAIL lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X600SLB
- ✓ 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 SI32X600SLB FAQ
Yes, the SI32X600SLB is discontinued. The direct replacement is the SAI32X600SLB. It matches the ISO 15552 mounting interface, 32 mm bore, 600 mm stroke, output force, G1/8 port, and LB mounting.
This double-acting cylinder uses a G1/8 port. It provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa.
