This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X750, 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 SI200X750
The AirTAC SI200 Standard Cylinder SI200X750 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 750mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X750, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X750
The AirTAC SI200X750 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 750 mm stroke. It delivers 15708 N push and 15080 N pull at 0.5 MPa, peaking at 3204 kgf. The direct is the SAI200X750, matching the interface, G3/4 port, and mounts exactly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. This no-magnet SKU cannot take a sensor, unlike CS1-B/DS1-B equipped units.

Where the Airtac SI200 Standard Cylinder SI200X750 Is Used
Heavy Press Forming
Generates up to 3204 kgf for large metal stamping and heavy-duty press operations in primary manufacturing.
Bulk Material Diversion
Drives heavy pivoting diverters on high-capacity aggregate or bulk material conveyor lines.
Replacing the Airtac SI200 Standard Cylinder SI200X750 with the SAI200X750
To replace the SI200X750, order the SAI200X750 direct. Confirm the ISO 15552 mounting accessory (LB, FA, CA, TC), the G3/4 port, and M36x2 thread. This SKU lacks a magnet, so it cannot accept position switches. For load holding, note that a plain cylinder drifts on air loss; use an external rod lock or pilot check valve, or specify the SAIL/BSAI lock variant. With a 750 mm stroke, use external guides to prevent rod bending. Neighbouring bores are 160 mm (10053 N [email protected]) and 125 mm (6136 N).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X750
- ✓ 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 SI200X750 FAQ
Yes, the SI200X750 is discontinued. The direct replacement is the SAI200X750, a true ISO 15552 profile cylinder that matches the 200 mm bore, 750 mm stroke, output force, G3/4 port, and mounting dimensions.
It operates at 30-500 mm/s. Forces are: 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. The G3/4 port and 50 mm cushions handle the mass.
