This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X75H, 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 SI160X75H
The AirTAC SI160 Standard Cylinder SI160X75H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X75H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X75H
The AirTAC SI160X75H is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 75 mm stroke. Designed for high-temperature environments, it features a Viton H seal (0-150 C) and delivers 10053 N push force at 0.5 MPa through its G3/4 port. AirTAC replaced this EOL unit with the SAI160X75H, a direct upgrade retaining the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions.
The SAI replacement introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S), so it cannot accept position sensors.

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 SI160X75H Is Used
Heavy Stamp Pressing
Applies the 14074 N push force at 0.7 MPa to seat heavy components or form metal in automated stamping lines, utilizing the 50 mm adjustable cushion to absorb end-of-stroke impact.
High-Temp Actuation
Operates reliably in heated industrial zones up to 150 C thanks to the Viton H seal, driving 75 mm motions in drying ovens or thermal forming equipment where standard NBR seals would fail.
Replacing the Airtac SI160 Standard Cylinder SI160X75H with the SAI160X75H
To replace the discontinued SI160X75H, order the SAI160X75H. Verify your existing fixture's ISO 15552 mounting interface (LB, FA, TC, etc.), the 75 mm stroke, and the G3/4 port. Because this is a non-magnet SKU, it cannot support legacy CS1-B/DS1-B sensors; if position detection is required, switch to an SAI model with the S suffix. The SAI family also adds SAIL (air-released lock) and BSAI (clamp-lock) variants the SI lacked, which are necessary if you need to hold a load without live air, as standard cushions only decelerate. If downsizing, a 125 mm bore yields 6136 N push at 0.5 MPa; if upsizing, a 200 mm bore provides 15708 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X75H
- ✓ 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 SI160X75H FAQ
Yes, the SI160X75H is discontinued. The direct replacement is the SAI160X75H. It shares the exact ISO 15552 mounting interface, 160 mm bore, 75 mm stroke, G3/4 port, and force ratings, but adds an upgraded two Y-shaped element piston seal for longer life.
At 0.5 MPa it provides 10053 N push and 9425 N pull; at 0.7 MPa it pushes 14074 N, and 18095 N at 0.9 MPa. The theoretical maximum is 2050 kgf at 1.0 MPa. It operates at 30-500 mm/s, uses a G3/4 port, and the Viton H seal supports temperatures from 0 to 150 C.
