This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X155TC, 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 SI160X155TC
The AirTAC SI160 Standard Cylinder SI160X155TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 155mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X155TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X155TC
The AirTAC SI160X155TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 155 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X155TC, retaining the exact TC trunnion mount, M36x2 rod thread, and 50 mm cushions.
Because this SKU lacks the -S magnet, it cannot accept a position sensor. The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure, and adds SAIL or BSAI lock variants the SI lacked.

Where the Airtac SI160 Standard Cylinder SI160X155TC Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring up to 10053 N of push force at 0.5 MPa, utilizing the 50 mm adjustable cushions to halt the massive payload smoothly.
Automated Assembly Forming
Provides the robust linear motion needed to seat heavy automotive or industrial components, relying on the rigid ISO 15552 TC trunnion mount to handle structural stress.
Industrial Material Loaders
Pushes substantial weighted pallets or chassis frames into position, where the 160 mm bore delivers enough thrust to overcome high friction without stalling.
Replacing the Airtac SI160 Standard Cylinder SI160X155TC with the SAI160X155TC
To replace the SI160X155TC, order the SAI160X155TC and confirm the ISO 15552 TC trunnion interface, 155 mm stroke, and G3/4 port. This non-magnetic SKU cannot hold a switch; if sensing is needed, select an SAI model with the S suffix for current AirTAC switches. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding. For sizing, neighboring bores (125 mm or 200 mm) offer different force classes, while this 160 mm bore provides 14074 N at 0.7 MPa. Since the 155 mm stroke is under 300 mm, side-load risks are minimal, but always verify rod alignment.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X155TC
- ✓ 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 SI160X155TC FAQ
Yes, the SI160X155TC is discontinued. The direct replacement is the SAI160X155TC. It maintains the exact ISO 15552 mounting interface, 160 mm bore, 155 mm stroke, G3/4 port, and TC trunnion mount, fitting directly into existing fixtures.
The G3/4 port feeds a 40 mm rod. At 0.5 MPa it yields 10053 N push and 9425 N pull. At 0.7 MPa push is 14074 N, and 18095 N at 0.9 MPa. The theoretical max is 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
