This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X150, 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 SID63X150
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X150 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X150, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X150
The AirTAC SID63X150 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. 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. This SKU has no -S magnet and cannot take a sensor. The bore sets the port to G3/8, with an M16x1.5 rod thread and 30 mm cushions.
This SID model is discontinued and end-of-life. The direct replacement is the SAID63X150, matching the ISO 15552 interface, 150 mm stroke, force, and mounting. The SAI family uses an upgraded two Y-shaped one-way piston seal for low start-up pressure, and adds SAIL/BSAI lock variants. A plain cylinder drifts on air loss; cushions only decelerate.

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 SAID63X150 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 SID63X150 Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from a single piston, utilizing the equal both-ways 1962 N @0.7 MPa force to ensure perfectly synchronized machining without differential push/pull lag.
Anti-Rotation Transfer Gate
The twin-rod architecture prevents mechanical twist during lateral product diversion on a 150 mm stroke, maintaining precise alignment without needing external linear guides.
Symmetric Clamping Jig
Clamps a workpiece from both sides evenly. The rear rod acts as a mechanical cam follower while the front rod applies the 1402 N @0.5 MPa clamping force safely.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X150 with the SAID63X150
Replace the discontinued SID63X150 directly with the SAID63X150, reusing the exact ISO 15552 mounting (Basic, FA, LB, TC) and G3/8 port. Size both ways by checking neighbor bores: the 50 mm yields 825 N @0.5 MPa, while the 80 mm yields 2268 N @0.5 MPa, both equal in push and pull. A double rod is right when you need anti-rotation, to drive two tools, or to mount a sensor cam on the back rod. This non-magnetic SKU cannot take a switch; add the -S suffix for legacy CS1-B/DS1-B sensor accuracy. For stroke lengths >=300 mm, verify side-load bearing limits. For held loads, use an external rod lock or SAIL/BSAI variant, as air cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X150
- ✓ 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 SID63X150 FAQ
Yes, the SID63X150 is discontinued. The direct replacement is the SAID63X150. It shares the identical ISO 15552 interface, 63 mm bore, 150 mm stroke, G3/8 port, and mounting, but features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
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 air port is G3/8, speed is 30-800 mm/s, and it features 30 mm adjustable cushions at each end.
