This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X300TC, 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 SI160X300TC
The AirTAC SI160 Standard Cylinder SI160X300TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 300mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X300TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X300TC
The AirTAC SI160X300TC is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 300mm stroke. It delivers 10053N push force at 0.5MPa via a G3/4 port. Because this legacy unit lacks a magnet, it cannot accept a position sensor. The direct replacement is the SAI160X300TC, matching the TC trunnion mount, M36x2 thread, and 50mm cushions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants absent in the SI line.

Where the Airtac SI160 Standard Cylinder SI160X300TC Is Used
Heavy Stamp Presses
Drives large stamping dies requiring 10053N push force at 0.5MPa, utilizing the 50mm adjustable cushions to absorb heavy kinetic energy at stroke ends.
Large Clamp Fixtures
Secures bulky weldments or machined components using the TC trunnion mount to accommodate pivoting arc movements during the clamping cycle.
Replacing the Airtac SI160 Standard Cylinder SI160X300TC with the SAI160X300TC
To replace the SI160X300TC, order the SAI160X300TC. Verify the ISO 15552 TC trunnion interface, 160mm bore, 300mm stroke, G3/4 port, and M36x2 rod thread. Since this SKU has no magnet, you cannot mount CS1-B/DS1-B sensors; order an SAI with the S suffix if sensing is needed. Sizing both ways: a 200mm bore offers more force, while a 125mm bore provides 6136N [email protected]. At 300mm stroke, use external guides to prevent rod bending and side-load wear. For load holding on air loss, note that cushions only decelerate; add an external pilot check valve or use the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X300TC
- ✓ 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 SI160X300TC FAQ
Yes, the SI160X300TC is discontinued. The direct replacement is the SAI160X300TC. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the exact 160mm bore, 300mm stroke, G3/4 port, and TC trunnion mount.
This double-acting cylinder uses a G3/4 air port. It generates 10053N push and 9425N pull at 0.5MPa, 14074N push at 0.7MPa, 18095N push at 0.9MPa, and a theoretical maximum of 2050 kgf at 1.0MPa. Operating speed is 30-500 mm/s.
