This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX115, 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 SI160BX115
The AirTAC SI160 Standard Cylinder SI160BX115 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 115mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX115, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX115
The AirTAC SI160BX115 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 115 mm stroke, delivering 10053 N push force at 0.5 MPa. It features a G3/4 port, a 40 mm SUS304 stainless steel rod (the -B option for corrosion resistance), and 50 mm adjustable air cushions. Because this SKU lacks a -S magnet, it cannot accept a position sensor.
The direct replacement is the SAI160BX115, matching the ISO 15552 mounting interface, bore, stroke, force, and port. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note that a plain cylinder drifts without live air; for load holding, consider the SAIL lock or BSAI clamp-lock variants.

Where the Airtac SI160 Standard Cylinder SI160BX115 Is Used
Heavy Machinery Forming
Drives large press beds and forming dies requiring 10053 N of push force at 0.5 MPa, utilizing the 50 mm adjustable cushions to absorb heavy impact.
Automated Clamp Actuation
Secures oversized castings during machining, providing 9425 N pull force at 0.5 MPa while matching existing ISO 15552 fixture interfaces.
Replacing the Airtac SI160 Standard Cylinder SI160BX115 with the SAI160BX115
To replace the SI160BX115, order the SAI160BX115 to retain the exact ISO 15552 mounting dimensions, 115 mm stroke, G3/4 port, and 160 mm bore. Confirm your mounting accessory (LB, FA, TC, etc.) and thread type (PT, G, or NPT). Since this specific SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, switch to a current SAI switch with the magnet option. For sizing alternatives, a 200 mm bore offers higher force, while a 125 mm bore provides 6136 N push at 0.5 MPa. Because this is a non-locking cylinder, the 50 mm cushions only decelerate the load; it will drift on air loss. For secure holding, specify the SAIL air-released lock, the BSAI clamp-lock, or an external pilot check valve. Operating speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX115
- ✓ 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 SI160BX115 FAQ
Yes, the AirTAC SI160BX115 is discontinued. The direct replacement is the SAI160BX115. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 115 mm stroke, 10053 N force, G3/4 port, and mounting interface. The SAI simply upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure.
This 160 mm bore cylinder features a G3/4 air port and a 40 mm piston rod. 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. It operates at 30-500 mm/s.
