This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX130, 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 SI160 Standard Cylinder SI160AX130
The AirTAC Airtac SI160 Standard Cylinder SI160AX130 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 130mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX130, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX130
The AirTAC SI160AX130 is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 130mm stroke, delivering 10053N push force at 0.5MPa. The direct replacement is the SAI160AX130, matching the bore, stroke, 2050kgf max force, G3/4 port, and ISO 15552 mounting interface. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.
This specific SKU features a SUS420J2 stainless steel rod (the -A option) for corrosion resistance. It lacks a magnet, so it cannot accept a CS1-B or DS1-B sensor. Note that plain cylinders drift without live air; use a SAIL lock variant or external pilot check valve for load holding.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SI160 Standard Cylinder SI160AX130 Is Used
Heavy Stamp Pressing
Leverages the 14074N push force at 0.7MPa to form thick metal plates and operate heavy-duty stamping dies.
Large Mold Clamping
Secures oversized injection molds in place using the 9425N pull force at 0.5MPa during heavy industrial forming cycles.
Replacing the Airtac SI160 Standard Cylinder SI160AX130 with the SAI160AX130
To replace the SI160AX130, order the SAI160AX130 to get the exact ISO 15552 mounting interface, 130mm stroke, G3/4 port, and M36x2 rod thread. Confirm you need the SUS420J2 stainless rod (-A) instead of standard carbon steel. Because this SKU has no -S magnet, it cannot support position sensing; if you require switches, select an SAI equivalent with the magnet option and use current AirTAC switches. If sizing down, a 125mm bore provides 6136N push at 0.5MPa; if sizing up, a 200mm bore offers 15708N. For suspended loads, remember the air cushion only decelerates at stroke end and does not hold the load on air loss—specify a SAIL air-released lock, BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX130
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160AX130 FAQ
Yes, the AirTAC SI160AX130 is discontinued. The direct replacement is the SAI160AX130. It is dimensionally interchangeable per ISO 15552, retaining the exact same 160mm bore, 130mm stroke, G3/4 port, and mounting fixtures. The SAI simply upgrades the piston seal to two Y-shaped one-way elements for longer life and lower start-up pressure.
This double-acting cylinder has a G3/4 air port. The thrust ratings are: 10053N push and 9425N pull at 0.5MPa; 14074N push at 0.7MPa; 18095N push at 0.9MPa; and a theoretical maximum force of 2050kgf at 1.0MPa. The piston rod is 40mm with an M36x2 thread, and the cushion stroke is 50mm at each end.
