This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X500, 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 SID63X500
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X500 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 500mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X500, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X500
The AirTAC SID63X500 is a discontinued ISO 15552 double-acting double-rod cylinder. A rod exits both ends on one piston, meaning both faces use the rod-side area, so push and pull force are equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. It features a 63mm bore, 500mm stroke, M16x1.5 rod thread, G3/8 port, and 30mm adjustable cushions. The direct replacement is the SAID63X500, matching the interface, force, and mounting.
The SAID successor uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life, and introduces SAIL and BSAI lock variants the SI line lacked. For this non-magnet SKU, sensors cannot be fitted. Note that air cushions only decelerate near stroke end; a plain cylinder drifts on air loss, so use an external rod lock for held loads.

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 SAID63X500 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 SID63X500 Is Used
Equal-Force Transfer
Drives a conveyor pusher where the return stroke must match the extend stroke force, utilising the 1402 N @0.5 MPa output both ways without requiring a larger bore.
Dual-Tool Machining
Simultaneously operates two opposing fixtures via the twin rods exiting both ends, ensuring perfectly synchronised clamping across a 500mm travel.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X500 with the SAID63X500
To replace the discontinued SID63X500, specify the SAID63X500 direct: it preserves the ISO 15552 mounting interface, 63mm bore, 500mm stroke, G3/8 port, and equal both-ways force. Size both directions by the 1402 N @0.5 MPa output, checking neighbouring bores (50mm or 80mm) if your payload changes. A double-rod cylinder is right when you need equal force both ways, anti-rotation stability, or a back rod to carry a sensor cam or drive two tools. Reuse FA, LB, or TC mounts. This SKU lacks the -S magnet, so it cannot take switches. For the 500mm stroke, add external guides to prevent rod bending under side-load. Never rely on cushions for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X500
- ✓ 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 SID63X500 FAQ
Yes, the SID63X500 is discontinued. The direct replacement is the SAID63X500, which matches the ISO 15552 interface, 63mm bore, 500mm stroke, G3/8 port, and mounting hardware.
As 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 thread is M16x1.5, and speed is 30-800 mm/s.
