This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X500S, 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 SID160X500S
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X500S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 500mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X500S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X500S
The AirTAC SID160X500S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal at 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. This model is discontinued; the direct replacement is the SAID160X500S, retaining the 160mm bore, 500mm stroke, G3/4 port, and M36x2 rod thread. The SAI upgrade uses a two-piece Y-shaped piston seal for lower start-up pressure and longer life.
Because both faces use the rod-side area, the back rod can carry a sensor cam or drive a second tool without altering the force profile. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that a plain cylinder does not hold loads on air loss; the 50mm adjustable cushions only decelerate near stroke end, so use an external rod lock for held loads.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAID160X500S 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 SID160X500S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously using both rod ends, ensuring perfectly synchronized clamping and milling with equal 9425 N force in both directions.
High-Capacity Transfer Pusher
Shifts heavy pallets along a conveyor line where the 160mm bore provides 13194 N @0.7 MPa of push and pull force, while the second rod operates a mechanical diverter.
Vertical Lift Gate Actuator
Raises and lowers heavy material handling gates with equal force both ways, utilizing the double-rod design to prevent sagging and maintain precise vertical alignment.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X500S with the SAID160X500S
To replace the discontinued SID160X500S, install the SAID160X500S directly using the same ISO 15552 mounting interface and FA, LB, or TC mounts. Size both ways by verifying the equal push/pull force of 9425 N @0.5 MPa against your load, stepping to neighbour bores if higher capacity is needed. A double rod is right when you need anti-rotation, equal force both ways, or a back rod to drive a second tool. The -S magnet supports legacy CS1-B/DS1-B sensors. For this 500mm stroke, add external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X500S
- ✓ 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 SID160X500S FAQ
Yes, the SID160X500S is discontinued. The direct replacement is the SAID160X500S, which matches the 160mm bore, 500mm stroke, G3/4 port, and ISO 15552 mounting. The SAI family also adds upgraded piston seals and lock variants.
Being a double-rod cylinder, force is equal both ways: 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The air port is G3/4, the rod thread is M36x2, and it features 50mm adjustable cushions at each end with a speed range of 30-500 mm/s.
