This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX130S, 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 SI32AX130S
The AirTAC SI32 Standard Air Cylinder SI32AX130S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 130mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX130S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX130S
The AirTAC SI32AX130S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 130 mm stroke. It features a SUS420J2 stainless piston rod and a built-in magnet for position sensing.
Order the direct replacement SAI32AX130S to keep existing fixtures. It shares the exact ISO 15552 mounting interface, bore, stroke, force and port. The SAI upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure, and adds SAIL, SAIF, and BSAI lock variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX130S 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 SAI32AX130S 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 SI32AX130S Is Used
Compact Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push small machined components out of a fixture, with the SUS420J2 rod resisting coolant splash.
Lightweight Panel Sorting
Cycles at 30-800 mm/s to divert lightweight plastic or aluminum panels on a conveyor, relying on the built-in magnet for position confirmation.
Pneumatic Gate Actuation
Drives a 130 mm stroke diverter gate in packaging lines, where the direct replacement SAI32AX130S maintains the exact ISO 15552 footprint during repairs.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX130S with the SAI32AX130S
To replace this SI32AX130S with the SAI32AX130S, verify the ISO 15552 mounting interface, 130 mm stroke, G1/8 port, and the -S magnet for legacy CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). If you need more push than 402 N at 0.5 MPa, step up to the 40 mm bore offering 628 N; if less force is acceptable, there is no smaller ISO 15552 standard bore. Remember a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify an SAIL lock variant. At 130 mm stroke, rod bending stress is low, but always guide the load to prevent side-loading.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX130S
- ✓ 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 SI32AX130S FAQ
Yes, the SI32AX130S is discontinued. The direct replacement is the AirTAC SAI32AX130S. It features the same ISO 15552 mounting interface, 32 mm bore, 130 mm stroke, G1/8 port, and output force, so it drops directly into existing fixtures without modifications.
The G1/8 port feeds a 32 mm bore that delivers 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 of 82 kgf at 1.0 MPa. The rod is 12 mm with an M10x1.25 thread, and speed ranges from 30-800 mm/s.
