This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X300, 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 SID160X300
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X300 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 300mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X300, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X300
The AirTAC SID160X300 is a double-acting double-rod ISO 15552 cylinder where a rod exits both ends, generating equal force in both directions (9425 N at 0.5 MPa). This 160 mm bore unit features a 40 mm rod, M36x2 thread, and a G3/4 port. The SID series is discontinued; the direct replacement is the SAID160X300, which reuses the same ISO 15552 mounting interface, bore, stroke, and porting.
Because both faces use the identical rod-side piston area, push and pull forces match exactly, preventing rod deflection and allowing the back rod to drive a second tool. The SAI upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure. As a non-magnet SKU, this cylinder cannot accept switches.

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 SAID160X300 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 SID160X300 Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously using both extending rods, ensuring perfectly synchronized part working and equal thrust in both directions.
Anti-Rotation Transfer Pusher
Pushes heavy pallets along a conveyor without rotational drift, relying on the dual-rod geometry to maintain strict alignment during the 300 mm transfer.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X300 with the SAID160X300
To replace the discontinued SID160X300, specify the SAID160X300; it is a direct swap retaining the ISO 15552 mounting interface, 1500 mm max standard stroke, and 50 mm adjustable cushions. Size both directions by matching the equal force (13194 N at 0.7 MPa) or stepping to neighbouring bores. A double rod is ideal when you need anti-rotation or a rear cam. Reuse FA, LB, or TC mounts. For the 300 mm stroke, use external guides to prevent rod bending. This non-magnet version cannot take sensors. For held loads, add an external rod lock or use SAIL/BSAI variants, as air cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X300
- ✓ 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 SID160X300 FAQ
Yes, the SID160X300 is discontinued. The direct replacement is the SAID160X300. It shares the exact ISO 15552 mounting interface, 160 mm bore, 300 mm stroke, G3/4 port, and equal both ways force, while adding an upgraded piston seal.
The double-rod design yields equal force both ways: 9425 N at 0.5 MPa, 13194 N at 0.7 MPa, and 16964 N at 0.9 MPa. Operating speed is 30-500 mm/s. The cylinder uses a G3/4 port, has a 50 mm adjustable cushion at each end, and operates at 0.15-1.0 MPa.
