This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID40X60, 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 SID40X60
The AirTAC Airtac SID Series Double-Rod Cylinder SID40X60 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 SAID40X60, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID40X60
The AirTAC SID40X60 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This configuration ensures push and pull force are 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 with an M12x1.25 thread, and the air port is G1/4. This SKU has no magnet (-S omitted), so it cannot accept a magnetic piston switch. Operating pressure is 0.15-1.0 MPa, with adjustable 27 mm cushions at each end.
This SID model is discontinued and the direct replacement is the SAID40X60, retaining the same ISO 15552 interface, bore, stroke, and mounting. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. A double rod provides anti-rotation stability and allows the back rod to drive a second tool. A plain cylinder does not hold loads on air loss; the cushion only decelerates. For held loads use an external rod lock or SAIL/BSAI variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID40X60 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAID40X60 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 SID40X60 Is Used
Gripper Actuation
Drives an external gripper where equal push and pull force is required to open and close tooling securely without rotational play.
Dual-Side Transfer
Uses the protruding back rod to push a secondary diverter simultaneously on a parallel conveyor line, syncing two actions from one piston.
Vertical Pressing
Applies a steady 528 N @0.5 MPa downward and upward force for light pressing tasks, maintaining equal both-ways dynamics.
Replacing the Airtac SID Series Double-Rod Cylinder SID40X60 with the SAID40X60
To replace the discontinued SID40X60, install the direct replacement SAID40X60 which matches the G1/4 port, 60 mm stroke, and ISO 15552 mounting interface (Basic, FA, LB, TC). Size both directions by equal force: this 40 mm bore yields 528 N @0.5 MPa both ways; step up to a 50 mm bore for 825 N or down to a 32 mm bore for 345 N. A double rod is right when you need anti-rotation resistance or a back rod to carry a sensor cam. Choose the -S magnet option if you need switch sensing, as this no-S SKU lacks it. For strokes >=300 mm, verify side-load bearing limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID40X60
- ✓ 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 SID40X60 FAQ
Yes, the SID40X60 is discontinued. The direct replacement is the SAID40X60. It shares the same ISO 15552 mounting interface, 40 mm bore, 60 mm stroke, G1/4 port, and equal both-ways force. The SAI family also adds SAIL and BSAI lock variants the SI line lacked.
Force is equal both ways: 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. The air port is G1/4. Speed is 30-800 mm/s. The rod is Ø16 mm with an M12x1.25 thread.
