This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX15S, 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 SI160BX15S
The AirTAC SI160 Standard Cylinder SI160BX15S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 15mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX15S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX15S
The AirTAC SI160BX15S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore, 15 mm stroke, and a SUS304 stainless steel rod. It delivers 10053 N push force at 0.5 MPa. The direct replacement is the SAI160BX15S, sharing the same interface, G3/4 port, and force. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure.
The -S magnet works with legacy CS1-B/DS1-B sensors. Note that air cushions only decelerate; use an external rod lock or SAIL/BSAI variant to hold loads.

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 SAI160BX15S 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 SI160BX15S Is Used
High-Force Clamping
Applies 10053 N of clamping force for securing heavy steel plates during machining operations.
Short-Stroke Pressing
Executes 15 mm high-thrust pressing tasks for inserting large bearings into industrial assemblies.
Heavy Duty Holding
Maintains robust 512 kg vertical lift holding positions in automated material handling lines.
Replacing the Airtac SI160 Standard Cylinder SI160BX15S with the SAI160BX15S
To replace the SI160BX15S, order the SAI160BX15S. Verify the ISO 15552 mounting interface, 15 mm stroke, G3/4 port, and SUS304 rod. If you need more force than the 10053 N at 0.5 MPa (or 14074 N at 0.7 MPa), step up to a 200 mm bore. If less force is needed, a 125 mm bore provides 6136 N. The standard cylinder lacks load-holding; for drop prevention, use an external pilot check valve or the SAIL lock variant. Although the 15 mm stroke is short, always minimize side loads to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX15S
- ✓ 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 SI160BX15S FAQ
Yes, the SI160BX15S is discontinued. The direct replacement is the SAI160BX15S, which maintains the same ISO 15552 mounting interface, 160 mm bore, 15 mm stroke, G3/4 port, and force ratings.
