This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X200, 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 SID63X200
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X200
The AirTAC SID63X200 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 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This SKU has no -S magnet and cannot take a sensor. The SID line is discontinued; the direct replacement is the SAID63X200, matching the 63mm bore, 200mm stroke, G3/8 port, and ISO 15552 mounting interface. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure.
Because both faces use the rod-side area, the double-rod design prevents rod rotation and lets the back rod drive a second tool. Operating pressure is 0.15-1.0 MPa, with a 30mm adjustable air cushion at each end. A plain cylinder does not hold loads on air loss; the cushion only decelerates. For held loads, use an external rod lock or SAIL/BSAI variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID63X200 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAID63X200 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 SID63X200 Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously from a single piston, utilizing the equal push and pull force to maintain perfectly synchronized cutting cycles.
Anti-Rotation Transfer Gate
Uses the dual-rod architecture to prevent mechanical twist during rapid package diversion on a high-speed line, ensuring smooth lateral transfers without binding.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X200 with the SAID63X200
To replace the discontinued SID63X200, install the direct replacement SAID63X200, which reuses the exact ISO 15552 mounting interface (Basic, FA, LB, TC) and G3/8 port. Size both ways by verifying the equal force (1402 N @0.5 MPa) meets your needs; if marginally short, step up to the 80mm bore, or drop to 50mm if overspecified. A double rod is right when you need anti-rotation, a back rod for a sensor cam, or to drive two tools. This non-magnetic SKU cannot take a switch. For stroke lengths >=300mm, verify side-load limits. Remember, air cushions only decelerate; they do not hold loads without live air.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X200
- ✓ 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 SID63X200 FAQ
Yes, the AirTAC SID63X200 is discontinued. The direct replacement is the SAID63X200. It matches the 63mm bore, 200mm stroke, G3/8 port, and ISO 15552 mounting interface, while adding an upgraded two Y-shaped one-way piston seal for lower start-up pressure.
Because it is a double-rod cylinder, force is equal both ways: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The air port is G3/8, the rod is Ø20mm with an M16x1.5 thread, and it features a 30mm adjustable cushion at each end.
