This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X600S, 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 SID63X600S
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X600S
The AirTAC SID63X600S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This architecture 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 bore is 63 mm, the piston rod is Ø20 mm, and the air port is G3/8. This SID model is discontinued; the direct replacement is the SAID63X600S, which reuses the same ISO 15552 mounting interface, stroke, and force. The SAI family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.
Because force is equal both ways, the back rod can carry a sensor cam or drive two tools simultaneously without force mismatch. With a -S magnet, this unit supports legacy CS1-B/DS1-B switches (the SAI replacement uses current AirTAC switches). Note that a plain cylinder does not hold loads on air loss; the 30 mm adjustable cushions only decelerate near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SID Series Double-Rod Cylinder SID63X600S Is Used
Dual-Station Transfer
Drives two opposing conveyor gating arms simultaneously from one central body, utilizing the equal both-ways force to ensure perfectly synchronized part diversion without mismatched timing.
Symmetrical Machining Fixture
Clamps a workpiece from both sides using the twin rods exiting the 63 mm bore, providing inherent anti-rotation resistance and balanced 1402 N @0.5 MPa holding power during milling.
External Guiding Press
Performs a 600 mm lengthwise forming operation where the extended stroke requires external slide rails to prevent rod bending, while the back rod drives a limit cam for position feedback.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X600S with the SAID63X600S
To replace the discontinued SID63X600S, specify the SAID63X600S; it is a direct swap retaining the 63 mm bore, 600 mm stroke, G3/8 port, M16x1.5 rod thread, and ISO 15552 mounting dimensions (Basic, FA, LB, TC, FTC, TCM1, TCM2). When sizing both ways, verify the equal force of 1402 N @0.5 MPa is sufficient, or step to the 80 mm bore (2268 N @0.5 MPa) if more force is needed, or down to the 50 mm bore (825 N @0.5 MPa) to save space. A double-rod design is the right choice when you need anti-rotation stability, equal push/pull power, or a back rod to mount a sensor cam. Because the stroke is 600 mm, external guides are recommended to prevent rod bending under side loads. Select the -S magnet option for switch mounting, and remember the 30 mm adjustable cushions only decelerate; they will not hold a load without live air.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X600S
- ✓ 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 SID63X600S FAQ
Yes, the SID63X600S is discontinued. The direct replacement is the SAID63X600S. It shares the same ISO 15552 mounting interface, 63 mm bore, 600 mm stroke, G3/8 port, and equal both-ways force. The SAI replacement also adds an upgraded two Y-shaped one-way piston seal for longer life.
The double-rod design yields equal force 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 Ø20 mm with an M16x1.5 thread, speed is 30-800 mm/s, and it features 30 mm adjustable cushions at each end.
