This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X650TC, 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 SI200 Standard Cylinder SI200X650TC
The AirTAC SI200 Standard Cylinder SI200X650TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 650mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X650TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X650TC
The AirTAC SI200X650TC is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 650 mm stroke. It delivers 15708 N push force at 0.5 MPa via a G3/4 port and TC trunnion mount. As a legacy unit, it must be replaced by the SAI200X650TC.
The SAI200X650TC is a direct upgrade retaining the exact ISO 15552 mounting interface, force, and stroke. It features an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure. Since this SKU lacks a magnet (-S), it cannot accept a CS1-B/DS1-B sensor. For load holding, note the cushion only decelerates; explore SAIL or BSAI lock variants.

Where the Airtac SI200 Standard Cylinder SI200X650TC Is Used
Heavy Press Forming
Applies 21991 N at 0.7 MPa for stamping and forming large metal panels, utilizing the 650 mm stroke to clear bulky workpieces.
Large Mold Handling
Actuates 650 mm extraction strokes to pull massive injection molds or cast parts from machinery, guided by external rails.
Replacing the Airtac SI200 Standard Cylinder SI200X650TC with the SAI200X650TC
To replace the SI200X650TC, order the SAI200X650TC ensuring the TC trunnion mount, G3/4 port, and 650 mm stroke match your fixture. With a 650 mm stroke, use external guides to prevent rod bending and side-load damage. If you need less force, step down to bore 160 (10053 N push). The plain cylinder drifts on air loss; for held loads use an external rod lock, pilot check valve, or SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X650TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI200 Standard Cylinder SI200X650TC FAQ
Yes, the SI200X650TC is discontinued. The direct replacement is the SAI200X650TC. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 650 mm stroke, G3/4 port, TC mount, and output force.
The G3/4 port feeds a 40 mm rod. It outputs 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N at 0.9 MPa, and a max theoretical force of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
