This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X80, 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 SID63X80
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X80 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 80mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X80, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X80
The AirTAC SID63X80 is a double-acting double-rod ISO 15552 cylinder where a rod exits both ends, ensuring force is equal both ways 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. It is discontinued; the direct replacement is the SAID63X80, sharing the G3/8 port, M16x1.5 rod thread, and 30 mm cushions.
The SAI upgrade uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Remember, 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 SAID63X80 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 SAID63X80 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 SID63X80 Is Used
Synchronized Tool Driving
Drives two separate mechanisms simultaneously from one piston, using both extending rods to maintain perfectly synchronized motion without adding a second cylinder.
Anti-Rotation Guiding
The dual-rod geometry provides inherent anti-rotation resistance, keeping the workpiece aligned during extension and retraction in precision handling tasks.
Equal Force Transfer
Ideal for shuttle or transfer systems requiring identical push and pull forces on a conveyor line, leveraging the equal both ways force of 1962 N at 0.7 MPa.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X80 with the SAID63X80
To replace the discontinued SID63X80, use the direct replacement SAID63X80 which matches the 63mm bore, 80mm stroke, and ISO 15552 mounting interface (Basic, FA, LB, TC). Size both ways by checking neighbor bores (50mm or 80mm) against your equal-both-ways force requirement. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools simultaneously. This non-magnetic SKU cannot take a sensor. For stroke lengths >=300mm, verify side-load limits to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X80
- ✓ 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 SID63X80 FAQ
Yes, the SID63X80 is discontinued. The direct replacement is the SAID63X80, which shares the same ISO 15552 interface, 80mm stroke, G3/8 port, and equal both ways force.
The SID63X80 features a G3/8 air port and provides equal both ways force of 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. It operates at 30-800 mm/s and has 30 mm adjustable cushions at each end.
