This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X100H, 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 SI32X100H
The AirTAC SI32 Standard Air Cylinder SI32X100H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X100H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X100H
The AirTAC SI32X100H is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 100 mm stroke. It delivers 402 N push force at 0.5 MPa through a G1/8 port. The direct replacement is the SAI32X100H, which matches the interface, bore, stroke, force, and mounting. This SI32X100H variant uses a Viton H seal, extending the operating temperature range from -20/+70 C up to 0-150 C.
The SAI upgrade features a revised piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Because this specific SKU lacks a magnet (-S), it cannot accept a CS1-B or DS1-B sensor.

Where the Airtac SI32 Standard Air Cylinder SI32X100H Is Used
Hot-End Ejection
Uses the Viton H high-temperature seal to push parts out of 150 C molding zones without degrading.
Light Package Divert
Cycles 100 mm to push small parcels on a conveyor, safely staying within the 241 N working load.
Lab Test Fixtures
Clamps delicate components with 402 N push force at 0.5 MPa, providing precise 32 mm bore actuation.
Replacing the Airtac SI32 Standard Air Cylinder SI32X100H with the SAI32X100H
To replace the discontinued SI32X100H, order the SAI32X100H. Verify the ISO 15552 mounting interface dimensions, 32 mm bore, 100 mm stroke, G1/8 port, and your specific mounting accessory (LB, FA, TC, etc.). This unit has no magnet, so position sensing is impossible; if you need switches, select an SAI32X100H-S and use current AirTAC switches. The Viton H seal is required for high-temperature 0-150 C environments. For higher force, consider the 40 mm bore (628 N push @0.5 MPa). A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X100H
- ✓ 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 SI32X100H FAQ
Yes, the SI32X100H is discontinued. The direct replacement is the SAI32X100H. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 100 mm stroke, force, G1/8 port, and mounting interface.
The 32 mm bore uses a G1/8 port. It generates 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 max of 82 kgf at 1.0 MPa. The speed range is 30-800 mm/s.
