This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X30, 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 SI160X30
The AirTAC Airtac SI160 Standard Cylinder SI160X30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 30mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X30
The AirTAC SI160X30 is a discontinued double-acting ISO 15552 profile cylinder delivering 10053 N push force at 0.5 MPa through a 160 mm bore and 30 mm stroke. It features a 40 mm carbon steel rod, M36x2 thread, and a G3/4 port. AirTAC replaced this EOL unit with the SAI160X30, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, and force.
The SAI upgrade utilizes an improved piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For sensing, note this specific SKU lacks the -S magnet and cannot accept a CS1-B/DS1-B switch. The SAI family also introduces SAIL and BSAI lock variants absent in the legacy SI line.

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 SI160X30 Is Used
Heavy-Duty Pressing
Drives 10053 N at 0.5 MPa for short-stroke stamping, riveting, and heavy press-fit assembly operations.
Industrial Clamping
Secures large molds or heavy fabricated components during machining with a robust 160 mm bore profile.
High-Force Plunging
Executes 30 mm plunge actions for actuating heavy gates, diverters, or thick material indexing pins.
Replacing the Airtac SI160 Standard Cylinder SI160X30 with the SAI160X30
To replace the discontinued SI160X30, order the SAI160X30. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G3/4 port connection, and the 30 mm stroke requirement. Because this SKU has no -S magnet, you cannot mount legacy CS1-B/DS1-B sensors; if position detection is needed, select an SAI160X30S. Sizing both ways: the 160 mm bore yields 10053 N push at 0.5 MPa (2050 kgf max at 1.0 MPa); if shifting down, a 125 mm bore provides 6136 N. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external pilot check valve or the SAIL/BSAI lock variants. Even at 30 mm stroke, verify rod-bending limits if heavy side-loads are present.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X30
- ✓ 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 SI160X30 FAQ
Yes, the SI160X30 is discontinued. The direct replacement is the SAI160X30. It shares the identical ISO 15552 mounting interface, 160 mm bore, 30 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The G3/4 port feeds a 40 mm rod yielding 10053 N push and 9425 N pull at 0.5 MPa. At 0.7 MPa push is 14074 N, and 18095 N at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
