This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X150TC, 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 SI160X150TC
The AirTAC SI160 Standard Cylinder SI160X150TC 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 SAI160X150TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X150TC
The AirTAC SI160X150TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 150 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160X150TC, which preserves the exact TC trunnion mounting, M36x2 thread, and output force.
This SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and longevity. Note this non-magnet SKU cannot accept a sensor; legacy CS1-B/DS1-B switches only fit -S models.

Where the Airtac SI160 Standard Cylinder SI160X150TC Is Used
Heavy Press Staging
Generates 14074 N at 0.7 MPa to position heavy steel blanks into stamping presses, utilizing the TC trunnion to handle offset center-of-gravity loads.
Injection Mold Clamping
Delivers up to 2050 kgf theoretical max force at 1.0 MPa for securing large injection mold halves, relying on the 50 mm adjustable cushions for smooth end-of-stroke deceleration.
Replacing the Airtac SI160 Standard Cylinder SI160X150TC with the SAI160X150TC
To replace the SI160X150TC, order the SAI160X150TC. Confirm the ISO 15552 TC trunnion interface, 150 mm stroke, and G3/4 port. Because this is a non-S model, it lacks a magnet and cannot host position sensors. If sizing alternatives, neighboring bores (125 mm or 200 mm) alter the 10053 N @0.5 MPa force. The air cushion only decelerates; it does not hold load. For drop prevention on air loss, specify an external pilot check valve or the SAIL/BSAI lock variants. The 150 mm stroke is under the 300 mm side-load threshold, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X150TC
- ✓ 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 SI160X150TC FAQ
Yes, the SI160X150TC is discontinued. The direct replacement is the SAI160X150TC. It features the same ISO 15552 mounting interface, 160 mm bore, 150 mm stroke, G3/4 port, and TC trunnion mount, fitting existing fixtures perfectly.
This double-acting cylinder uses a G3/4 air port. The thrust ratings are 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical maximum of 2050 kgf at 1.0 MPa.
