This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X75TC, 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 SI32X75TC
The AirTAC SI32 Standard Air Cylinder SI32X75TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 75mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X75TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X75TC
The AirTAC SI32X75TC is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 75 mm stroke. It delivers 402 N push force at 0.5 MPa and uses a G1/8 port. The direct replacement is the SAI32X75TC, matching the bore, stroke, force, port and TC trunnion mounting interface for existing fixtures.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Because this specific SI SKU lacks the -S magnet, it cannot accept a sensor. For locking needs the SI line lacked, the SAI family adds SAIL and BSAI variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X75TC 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 SAI32X75TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32X75TC Is Used
Small Part Ejection
Uses the 402 N push force to reliably knock small molded parts out of an injection molding fixture.
Package Diverter
Actuates a lightweight TC trunnion-mounted gate arm to sort small parcels on a packaging line.
Clamp Actuation
Provides low-force clamping for delicate electronics subassemblies where a 20 kg vertical lift margin is sufficient.
Replacing the Airtac SI32 Standard Air Cylinder SI32X75TC with the SAI32X75TC
To replace the SI32X75TC, order the SAI32X75TC. Verify the ISO 15552 TC trunnion mount, 75 mm stroke, G1/8 port, and M10x1.25 rod thread. This non-magnet SKU cannot take a switch. If sizing up, a 40 mm bore gives 628 N push at 0.5 MPa; sizing down is not an option below 32 mm. A plain cylinder drifts on air loss—the cushion only decelerates—so use a pilot check valve or SAIL lock to hold loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X75TC
- ✓ 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 SI32X75TC FAQ
Yes, the SI32X75TC is discontinued. The direct replacement is the SAI32X75TC. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the exact 32 mm bore, 75 mm stroke, G1/8 port, and TC trunnion mount.
This double-acting cylinder has 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 max of 82 kgf at 1.0 MPa.
