This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X150H, 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 SI160X150H
The AirTAC SI160 Standard Cylinder SI160X150H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 150mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X150H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X150H
The AirTAC SI160X150H is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 150 mm stroke. Built for high force, it delivers a push of 10053 N and pull of 9425 N at 0.5 MPa. The direct replacement is the SAI160X150H, matching the bore, stroke, 2050 kgf max force, G3/4 port, and ISO 15552 mounting interface. This -H variant specifies a Viton FKM seal, extending the operating temperature range from -20/+70 C up to 0-150 C for high-heat environments.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note that this specific SKU lacks a magnet (-S), so it cannot accept legacy CS1-B/DS1-B sensors.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X150H produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X150H Is Used
Heavy Stamp Pressing
Generates 14074 N of push force at 0.7 MPa, ideal for driving large metal stamping dies and heavy forming operations.
High-Tact Robotic Clamping
Provides a robust 9425 N pull force at 0.5 MPa for securing heavy cast iron molds during precision machining.
Replacing the Airtac SI160 Standard Cylinder SI160X150H with the SAI160X150H
To replace the discontinued SI160X150H, order the SAI160X150H. Confirm the ISO 15552 mounting interface (LB, FA, CA, TC, etc.), the 150 mm stroke, and the G3/4 port. Because this is a high-force 160 mm bore, sizing both ways is critical: a 125 mm bore offers 6136 N push at 0.5 MPa, while a 200 mm bore yields 15708 N. The rod is Ø40 mm with an M36x2 thread. This -H SKU uses a Viton seal for 0-150 C heat, but has no magnet, meaning no position sensing is possible. For load holding, remember a standard cylinder drifts without live air—the 50 mm adjustable cushions only decelerate. Use an external pilot check valve or the SAIL/BSAI lock variants for secure holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X150H
- ✓ 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 SI160X150H FAQ
Yes, the AirTAC SI160X150H is discontinued. The direct replacement is the SAI160X150H. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 150 mm stroke, force, G3/4 port, and mounting fixtures.
The 160 mm bore cylinder delivers a push of 10053 N and pull of 9425 N at 0.5 MPa. At 0.7 MPa it pushes 14074 N, and 18095 N at 0.9 MPa. The theoretical max force is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
