This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X50, 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 SID32X50
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 50mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X50
The AirTAC SID32X50 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force are equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. This model is discontinued; the direct replacement is the SAID32X50, matching the 32mm bore, 50mm stroke, G1/8 port, and mounting interface. The SAI upgrade features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
Because the second rod acts as an anti-rotation guide and can drive a second tool simultaneously, the design offers superior stability. Note this SKU lacks a magnet (-S) and cannot accept sensors. A plain cylinder does not hold loads on air loss; the 27mm adjustable cushion only decelerates near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID32X50 Is Used
Synchronized Tool Driving
Drives two separate mechanisms simultaneously from one piston, utilizing the dual extending rods for equal push and pull force in compact assembly machinery.
Anti-Rotation Guiding
The twin-rod architecture prevents piston rotation without external guides, ensuring precise linear positioning for handling and clamping tasks.
Transfer Pushers
Ideal for conveyor sorting stations where equal force is required in both directions to push and retract parts consistently at 30-800 mm/s.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X50 with the SAID32X50
To replace the discontinued SID32X50, install the SAID32X50 direct: it matches the ISO 15552 mounting, 50mm stroke, G1/8 port, and M10x1.25 rod thread. Choose a double-rod cylinder when you need equal force both ways or anti-rotation stability. If 345 N @0.5 MPa is insufficient, step up to the 40mm bore; if oversizing, drop to a smaller bore. Mounting options include Basic, FA, LB, and TC. Since this SKU lacks the -S magnet, it cannot use sensors. For stroke lengths >=300, verify side-load limits.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X50
- ✓ 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 SID32X50 FAQ
Yes, the SID32X50 is discontinued. The direct replacement is the AirTAC SAID32X50, which shares the identical ISO 15552 interface, 32mm bore, 50mm stroke, G1/8 port, and equal both ways force.
The bore is 32mm with a G1/8 air port and M10x1.25 rod thread. Because it is a double-rod cylinder, force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. Operating pressure is 0.15-1.0 MPa.
