This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X30S, 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 SID63X30S
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 30mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X30S
The AirTAC SID63X30S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This configuration means both faces use the rod-side area, making push and pull force equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The SID63X30S is discontinued and is replaced by the direct replacement SAID63X30S, which shares the exact 63mm bore, 30mm stroke, G3/8 port, and ISO 15552 mounting interface.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. A double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that air cushions only decelerate near stroke end; an external rod lock or SAIL/BSAI variant is required for load holding.

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 SAID63X30S 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 SID63X30S Is Used
Synchronized Gripper Actuation
Drives opposing gripper jaws simultaneously from a single piston, utilizing the equal both-ways force to maintain balanced clamping pressure on precision parts.
Dual-End Transfer Pusher
Uses the rod extending from the rear head to mount a sensor cam while the front rod pushes workpieces onto a conveyor, saving axial space.
Anti-Rotation Indexing Unit
The dual-rod geometry prevents mechanical twist during rapid 30mm indexing strokes, ensuring precise alignment for component placement tasks.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X30S with the SAID63X30S
To replace the discontinued SID63X30S, specify the SAID63X30S, which provides a direct solution matching the 63mm bore, 30mm stroke, M16x1.5 rod thread, G3/8 port, and ISO 15552 mounting dimensions. Size both ways by verifying the equal force of 1402 N @0.5 MPa meets your requirement, or step to neighbouring bores (50mm or 80mm) if capacity changes. A double-rod cylinder is the right choice 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. The -S suffix ensures piston magnet compatibility for legacy CS1-B/DS1-B sensors. Because this stroke is 30mm, side-load bending moments are minimal compared to longer strokes.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X30S
- ✓ 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 SID63X30S FAQ
Yes, the SID63X30S is discontinued. The direct replacement is the SAID63X30S. It shares the same ISO 15552 interface, 63mm bore, 30mm stroke, G3/8 port, and mounting options, while adding an upgraded piston seal.
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 operating speed is 30-800 mm/s, the rod is Ø20mm with an M16x1.5 thread, and it features a 30mm adjustable air cushion at each end.
