This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X500, 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 SID100X500
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X500 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X500, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X500
The AirTAC SID100X500 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal push and pull force of 3681 N at 0.5 MPa. Because both faces use the rod-side annulus area, it provides true symmetric thrust. This 100 mm bore, 500 mm stroke unit is discontinued; its direct replacement is the SAID100X500, retaining the identical G1/2 port, M20x1.5 rod thread, and 3681 N force. The SAI upgrade features a two-piece Y-shaped piston seal for lower start-up pressure and longer life.
This SKU lacks the -S magnet and cannot accept magnetic switches. Note that air cushions only decelerate the piston near stroke end; they do not hold loads on air loss. For held loads, use an external rod lock or the SAIL/BSAI lock variants.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID100X500 Is Used
Symmetric Machining Clamp
Provides equal clamping and release forces to hold workpieces securely during precision milling without rotational drift.
Dual-End Transfer Pusher
Drives two separate conveyor lanes simultaneously from a single piston, ensuring perfectly synchronized part movement.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X500 with the SAID100X500
To replace the discontinued SID100X500, specify the SAID100X500; it is a direct swap retaining the ISO 15552 mounting interface, 500 mm stroke, and 3681 N equal-both-ways force. Choose a double-rod design when you need anti-rotation stability or must drive two tools from one piston. Because thrust is equal both ways, size by verifying the 3681 N @0.5 MPa (5153 N @0.7) meets your load in both directions, or step to a larger bore if needed. Mounting options include Basic, FA, LB, and TC. Since this SKU lacks the -S magnet, add external sensors if detection is required. For the 500 mm stroke, use external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X500
- ✓ 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 SID100X500 FAQ
Yes, the SID100X500 is discontinued. The direct replacement is the SAID100X500. It shares the identical ISO 15552 mounting interface, 100 mm bore, 500 mm stroke, G1/2 port, and equal-both-ways force, but adds an upgraded two-piece Y-shaped piston seal for longer life.
Because it is a double-rod cylinder, force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The fixed air port is G1/2, the rod thread is M20x1.5, and it features 36 mm adjustable air cushions at each end. It operates at 30-800 mm/s.
