This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X500, 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 SID200X500
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X500 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 SAID200X500, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X500
The AirTAC SID200X500 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, making push and pull force equal at 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. This SKU has no -S magnet and cannot carry a sensor. It features a 40 mm rod, M36x2 thread, G3/4 port, and 50 mm adjustable cushions. The SID line is discontinued; the direct replacement is the SAID200X500, sharing the same interface, bore, stroke, and mounting.
The SAI upgrade uses a two-piece Y-shaped piston seal for low start-up pressure and long life. Because both faces use the rod-side area, force is equal both ways, preventing single-rod push mismatch. Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID200X500 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAID200X500 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 SID200X500 Is Used
Equal-Force Pressing
Drives a double-ended press where the return stroke must deliver the same 27141 N @0.9 MPa force as the advance, ensuring consistent forming pressure from both rod faces.
Dual-Tool Transfer
Uses the rear rod extension to actuate a secondary gripper or ejector on a conveyor line, synchronizing two separate motions without adding a second cylinder.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X500 with the SAID200X500
To replace the discontinued SID200X500, install the direct replacement SAID200X500, which preserves the ISO 15552 mounting interface, 500 mm stroke, G3/4 port, and equal-both-ways force. Size both directions by checking the 15080 N @0.5 MPa rating; if less force is needed, step down to the 160 mm bore (9425 N), or if more is required, confirm from datasheet as 200 mm is the largest. A double rod is right when you need equal push/pull force, anti-rotation stability, or a back rod to drive a second tool. Mounting options include Basic, FA, LB, and TC. For the 500 mm stroke, add external guides to prevent rod bending under side loads. This non-magnetic SKU cannot take switches.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X500
- ✓ 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 SID200X500 FAQ
Yes, the SID200X500 is discontinued. The direct replacement is the SAID200X500. It shares the same ISO 15552 interface, 200 mm bore, 500 mm stroke, G3/4 port, and equal-both-ways force. The SAI family also adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
Force is equal both ways (push and pull) because both piston faces use the rod-side area: 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. Speed is 30-500 mm/s. It uses a G3/4 port, 40 mm rod, M36x2 thread, and 50 mm adjustable cushions. The air cushion only decelerates near stroke end; it does not hold loads on air loss, so use an external rod lock or SAIL/BSAI variant for holding.
