This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X95, 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 SI32X95
The AirTAC SI32 Standard Air Cylinder SI32X95 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 95mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X95, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X95
The AirTAC SI32X95 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 95mm stroke. It delivers 402N push and 345N pull at 0.5MPa through a G1/8 port. AirTAC replaced this legacy unit with the SAI32X95, a direct sharing the exact mounting interface, bore, force and cushioning.
The SAI32X95 upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Because this specific SI SKU lacks the -S magnet, it cannot accept a CS1-B/DS1-B sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X95 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 SAI32X95 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 SI32X95 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight molded components out of a machining fixture.
Package Diversion
Actuates a routing gate at 30-800mm/s to sort small boxes on a packaging line without overwhelming the load.
Clamp Actuation
Provides the 345N pull force needed to retract a secondary clamping jaw in an automated assembly cell.
Replacing the Airtac SI32 Standard Air Cylinder SI32X95 with the SAI32X95
To replace the SI32X95, order the SAI32X95 keeping the identical 32mm bore, 95mm stroke, M10x1.25 rod thread and G1/8 port. Confirm your ISO 15552 mounting accessory (LB, FA, TC) and note this non-magnetic version cannot hold a switch. For higher force, the 40mm bore yields 628N push at 0.5MPa; for lighter duties, drop to a 20mm bore. A plain cylinder drifts on air loss, so for load holding use an external pilot check valve or the SAIL lock variant. At 95mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X95
- ✓ 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 SI32X95 FAQ
Yes, the SI32X95 is discontinued. The direct replacement is the AirTAC SAI32X95. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 95mm stroke, output force, G1/8 port and mounting interface.
The bore is 32mm with a G1/8 port. Force output is 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum of 82kgf at 1.0MPa.
