This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X336CB, 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 SI160X336CB
The AirTAC SI160 Standard Cylinder SI160X336CB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 336mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X336CB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X336CB
The AirTAC SI160X336CB is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 336 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI160X336CB, a direct sharing the identical CB clevis mount, M36x2 rod thread, and 50 mm cushions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. With no -S suffix, this SKU cannot take a sensor. For high heat, Viton H seals extend range to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X336CB Is Used
Heavy Press Forming
Drives large stamping dies with 10053 N thrust at 0.5 MPa, utilizing the 336 mm stroke to clear bulky tooling.
Automated Welding Clamp
Secures heavy structural beams via the CB clevis mount, absorbing shock with 50 mm adjustable cushions.
Replacing the Airtac SI160 Standard Cylinder SI160X336CB with the SAI160X336CB
To replace the SI160X336CB, order the SAI160X336CB and confirm the ISO 15552 CB clevis mount, G3/4 port, and 336 mm stroke. The SAI family adds SAIL (air-released lock) and BSAI (clamp-lock) variants the SI lacked; use these or an external pilot check valve, as a plain cylinder drifts on air loss—the cushion only decelerates. If sizing up or down, neighbor bores are 125 mm and 200 mm; at 0.5 MPa the 125 mm yields 6136 N push and the 200 mm yields 15708 N. Because the 336 mm stroke is long, use an external guide to prevent rod-bending side loads. This no-magnet SKU cannot accept CS1-B/DS1-B switches.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X336CB
- ✓ 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 SI160X336CB FAQ
Yes, the SI160X336CB is discontinued. The direct replacement is the SAI160X336CB. It shares the identical ISO 15552 mounting interface, 160 mm bore, 336 mm stroke, CB mount, and G3/4 port, fitting existing fixtures perfectly.
It features a G3/4 port and delivers 10053 N push / 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a theoretical max of 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
