This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X160, 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 SID100X160
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X160
The AirTAC SID100X160 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This means both faces use the rod-side area, so push and pull force are equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The bore is 100 mm, stroke is 160 mm, rod is Ø25 mm, and the air port is G1/2. This SID model is discontinued; the direct replacement is the SAID100X160, sharing the same ISO 15552 mounting interface, bore, stroke, and force.
The SAI replacement uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Because there is no -S suffix, this SKU cannot take a magnetic switch. A plain cylinder does not hold its load on air loss; the air cushion only decelerates near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID100X160 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAID100X160 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 SID100X160 Is Used
Dual-End Transfer Pusher
Drives a transfer carriage on a conveyor using both rod ends to push and retract equal loads without requiring a separate return cylinder.
Anti-Rotation Machining Clamp
Uses the twin-rod architecture to resist rotational torque during machining, holding a workpiece securely with equal push and pull force.
Symmetrical Indexing Unit
Indexes a fixture from one station to another by attaching cams to both extending rods, ensuring perfectly balanced motion in both directions.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X160 with the SAID100X160
Replace the discontinued SID100X160 directly with the SAID100X160, reusing the existing FA, LB, or TC ISO 15552 mounts. Size both ways by checking neighbour bores; the equal both-ways force is 3681 N @0.5 MPa. Choose a double rod when you need anti-rotation stability or to drive two tools. Since this SKU lacks the -S magnet, it cannot take a sensor. For this 160 mm stroke, side-load is minimal, but for stroke >=300 mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X160
- ✓ 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 SID100X160 FAQ
Yes, the SID100X160 is discontinued. The direct replacement is the SAID100X160, which matches the ISO 15552 interface, bore, stroke, G1/2 port, and force. The SAI family also adds SAIL and BSAI lock variants the SI line lacked.
Because it is a double-rod cylinder, force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. Speed is 30-800 mm/s. The bore is 100 mm with a 36 mm adjustable cushion at each end.
