This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX750, 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 SI32AX750
The AirTAC SI32 Standard Air Cylinder SI32AX750 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 750mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX750, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX750
The AirTAC SI32AX750 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 750 mm stroke. It delivers 402 N push force at 0.5 MPa and features a G1/8 port. The direct replacement is the SAI32AX750, which shares identical ISO 15552 mounting-interface dimensions, stroke, and output force.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this specific SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors. The SAI family also adds SAIL, SAIF, and BSAI lock variants.

Where the Airtac SI32 Standard Air Cylinder SI32AX750 Is Used
Light-Part Diversion
Pushes lightweight packages on a 750 mm stroke across a conveyor belt, utilizing the 402 N push force at 0.5 MPa effectively.
Compact Ejection
Ejects small manufactured parts from a fixture over a long distance, taking advantage of the 32 mm bore and SUS420J2 stainless rod.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX750 with the SAI32AX750
To replace the SI32AX750, order the SAI32AX750. Confirm the ISO 15552 mounting fixture, 750 mm stroke, G1/8 port, and M10x1.25 rod thread. Because this SKU lacks a magnet, it cannot support position sensing; if you need switches, select an SAI model with the S suffix for current AirTAC sensors. The SUS420J2 stainless rod (-A) is standard here, offering corrosion resistance over carbon steel. With a 750 mm stroke, prevent rod bending by using external guides to manage side loads. For sizing, a 40 mm bore offers 628 N push at 0.5 MPa if you need more force, while a 20 kg vertical lift is safe here. A plain cylinder drifts without live air; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX750
- ✓ 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 SI32AX750 FAQ
Yes, the SI32AX750 is discontinued. The direct replacement is the SAI32AX750. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 750 mm stroke, force, G1/8 port, and mounting interface.
The bore is 32 mm with a G1/8 port. The thrust is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical maximum force of 82 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
