This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X35H, 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 SI160X35H
The AirTAC SI160 Standard Cylinder SI160X35H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 35mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X35H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X35H
The AirTAC SI160X35H is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 35 mm stroke. Built with an extruded aluminum barrel and adjustable air cushions at both ends, it delivers 10053 N of push force at 0.5 MPa. This specific SKU utilizes a Viton H seal for high-temperature environments up to 150 C and lacks a magnet, meaning it cannot accept position sensors. AirTAC replaced this legacy unit with the SAI160X35H.
The SAI160X35H is a direct replacement, retaining the exact ISO 15552 mounting interface, 40 mm rod, M36x2 thread, and G3/4 port. The SAI upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. The SAI family also adds lock and valve variants the original SI lacked.

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 SI160X35H Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 10053 N of push force at 0.5 MPa, utilizing the 35 mm stroke for rapid, high-impact short-travel actuation.
High-Tact Forming
Ideal for metal forming operations in elevated temperature environments, leveraging the Viton H seal rated for 0 to 150 C to maintain reliability under thermal stress.
Replacing the Airtac SI160 Standard Cylinder SI160X35H with the SAI160X35H
To replace the discontinued SI160X35H, order the SAI160X35H. Verify your existing fixture matches the ISO 15552 mounting dimensions and confirm the G3/4 port, M36x2 rod thread, and 50 mm cushion stroke. Because this SKU has no magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, switch to a current AirTAC switch on an SAI model with a magnet. When sizing, note the 14074 N push force at 0.7 MPa; if you need less force, the neighboring 125 mm bore offers 6136 N at 0.5 MPa. A plain cylinder does not hold load without live air—the cushion only decelerates. For load holding on air loss, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. The Viton H seal allows operation up to 150 C.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X35H
- ✓ 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 SI160X35H FAQ
Yes, the AirTAC SI160X35H is discontinued. The direct replacement is the SAI160X35H. It shares the identical ISO 15552 mounting interface, 160 mm bore, 35 mm stroke, output force, G3/4 port, and Viton H high-temperature seal, fitting directly into existing fixtures.
This 160 mm bore cylinder features a G3/4 air port. It delivers a push force of 10053 N and a pull force of 9425 N at 0.5 MPa. At 0.7 MPa the push force is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical maximum force is 2050 kgf at 1.0 MPa.
