This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X500S, 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 SID Series Double-Rod Cylinder SID200X500S
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X500S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 500mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID200X500S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X500S
The AirTAC SID200X500S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal at 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. This bore features a 40 mm rod, M36x2 thread, 50 mm adjustable cushions, a G3/4 port, and a 30-500 mm/s speed range. The SID line is discontinued; the direct replacement is the SAID200X500S, sharing the same interface, bore, stroke, and mounting.
The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches. A plain cylinder drifts on air loss; cushions only decelerate, so use an external rod lock for held loads.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAID200X500S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SID Series Double-Rod Cylinder SID200X500S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously from one piston, utilizing the equal both-ways force to deliver consistent 21110 N clamping at 0.7 MPa on both ends.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X500S with the SAID200X500S
To replace the discontinued SID200X500S, specify the SAID200X500S, which reuses the exact ISO 15552 mounting footprint and G3/4 port. Because force is equal both ways, size it by matching the 21110 N @0.7 MPa output; if less force is needed, step down to a 160 mm bore, or step up if higher capacity is required. Choose a double-rod design when you need anti-rotation stability or need to drive two tools simultaneously. Select FA, LB, or TC mounts to suit your frame, and retain the -S magnet for sensor feedback. For this 500 mm stroke, add external guide rails to prevent rod bending and absorb side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X500S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SID Series Double-Rod Cylinder SID200X500S FAQ
Yes, the SID200X500S is discontinued. The direct replacement is the SAID200X500S. It shares the identical ISO 15552 mounting interface, 200 mm bore, 500 mm stroke, G3/4 port, and equal both-ways force, but adds an upgraded two Y-shaped one-way piston seal.
Because it is a double-rod cylinder, force is equal in both directions: 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. The fluid port is G3/4, the rod is 40 mm with an M36x2 thread, and speed is 30-500 mm/s.
