This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID40X60S, 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 SID40X60S
The AirTAC Airtac SID Series Double-Rod Cylinder SID40X60S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 60mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID40X60S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID40X60S
The AirTAC SID40X60S 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, making push and pull force equal at 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. The bore is 40 mm, the piston rod is Ø16 mm, and the air port is G1/4. This SID model is discontinued; the direct replacement is the SAID40X60S, sharing the same interface, stroke, and mounting.
The SAI replacement uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. A double-rod design prevents rod rotation and lets the back rod carry a sensor cam. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that a plain cylinder does not hold its load on air loss; the cushion only decelerates near stroke end, so use an external rod lock for held loads.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAID40X60S 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 SID40X60S Is Used
Synchronized Tool Driving
Drive two separate mechanisms simultaneously from one cylinder, utilizing the equal push and pull force of both extending rods for synchronized machining operations.
Anti-Rotation Positioning
Prevent piston rod rotation during precise component placement. The dual-rod architecture provides inherent torsional stability for strict alignment tasks.
Dual-End Sensor Cam
Use the rear exiting rod to carry a sensor cam. This leaves the primary working rod unobstructed while providing reliable position feedback via the magnetic -S switch.
Replacing the Airtac SID Series Double-Rod Cylinder SID40X60S with the SAID40X60S
To replace the discontinued SID40X60S, install the direct replacement SAID40X60S, which preserves the ISO 15552 mounting interface, 60 mm stroke, and G1/4 port. Size both ways by checking neighbour bores while relying on the equal both-ways force; if 528 N @0.5 MPa is insufficient, step up to the 50 mm bore, or drop to 32 mm if lower force is acceptable. A double rod is right when you need anti-rotation stability or want to drive two tools from one cylinder. Mounting options include Basic, FA, LB, and TC brackets. The -S magnet supports legacy CS1-B/DS1-B switches. For this 60 mm stroke, side-load is minimal, but for any stroke >=300 mm, ensure guide alignment to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID40X60S
- ✓ 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 SID40X60S FAQ
Yes, the AirTAC SID40X60S is discontinued. The direct replacement is the SAID40X60S. It shares the same ISO 15552 interface, 40 mm bore, 60 mm stroke, G1/4 port, and mounting options, while adding an upgraded piston seal.
Because it is a double-rod cylinder, force is equal both ways: 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. The operating speed is 30-800 mm/s.
