This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX290S, 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 SI200BX290S
The AirTAC SI200 Standard Cylinder SI200BX290S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 290mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX290S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX290S
The AirTAC SI200BX290S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 290mm stroke, delivering 15708 N push force at 0.5 MPa through its G3/4 port. The direct replacement is the SAI200BX290S, matching the exact bore, stroke, force, port and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. This -S SKU includes a piston magnet for legacy CS1-B/DS1-B sensors, and the -B rod option provides SUS304 stainless steel for corrosion resistance.

Where the Airtac SI200 Standard Cylinder SI200BX290S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 15708 N of push force at 0.5 MPa with stable 290mm travel.
Large Mold Clamping
Secures oversized industrial molds in place, utilizing the 50mm adjustable air cushions to decelerate heavy masses.
Replacing the Airtac SI200 Standard Cylinder SI200BX290S with the SAI200BX290S
To replace the SI200BX290S, order the SAI200BX290S and confirm the ISO 15552 mounting interface, 290mm stroke, G3/4 port and mounting accessory. The SAI family adds SAIL (air-released lock) and BSAI (clamp-lock) variants the SI lacked; a plain cylinder drifts on air loss as the cushion only decelerates, so use these or an external pilot check valve for load holding. Sizing both ways: stepping down to a 160mm bore yields 10053 N push at 0.5 MPa, while a 200mm bore hits 21991 N at 0.7 MPa. For any stroke at or over 300mm, verify guide alignment to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX290S
- ✓ 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 SI200BX290S FAQ
Yes, the SI200BX290S is discontinued. The direct replacement is the SAI200BX290S, which shares the same ISO 15552 mounting interface, 200mm bore, 290mm stroke, output force and G3/4 port.
It features a G3/4 air port and delivers 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a theoretical max force of 3204 kgf at 1.0 MPa.
