This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAID200X800S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAID200X800S in place of this model. 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 SID200X800S
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X800S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAID200X800S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X800S
The AirTAC SID200X800S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force remain equal both ways at 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. This discontinued model features a 200mm bore, 800mm stroke, 40mm piston rod, G3/4 air port, and M36x2 rod-end thread. The exact drop-in replacement is the SAID200X800S, matching the ISO 15552 mounting interface, bore, stroke, and port size.
Because the second rod can carry a sensor cam or drive two tools simultaneously, it provides inherent anti-rotation benefits. The SAI replacement upgrades the piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, the safe working load is roughly 9048 N (60% of the 15080 N @0.5 MPa figure), and the vertical lift capacity is about 769 kg with a 2:1 margin. Note that air cushions only decelerate; an external rod lock or pilot-operated check valve is required for load holding.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAID200X800S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SID Series Double-Rod Cylinder SID200X800S Is Used
Dual-Side Machining Station
Drives opposing machining heads simultaneously using both extending rods, ensuring perfectly synchronized part fabrication.
Anti-Rotation Transfer Unit
Moves heavy workpieces along a conveyor without rotational drift, leveraging the inherent guidance of the twin-rod assembly.
Symmetric Pallet Lifter
Lifts and lowers pallets with equal push and pull force on both faces, maintaining balance for vertical material handling.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X800S with the SAID200X800S
To replace the discontinued SID200X800S, install the drop-in SAID200X800S, which preserves the ISO 15552 mounting interface, 200mm bore, 800mm stroke, and G3/4 port. Size both ways by verifying the equal both-ways force (15080 N @0.5 MPa) meets your push and pull requirements, or step to neighboring bores if margins allow. A double-rod design is right when you need anti-rotation, dual-tool driving, or a back rod for sensor cams. Mounting options include Basic, FA, LB, and TC. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches. For the 800mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X800S
- ✓ 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 SID200X800S FAQ
Yes, the SID200X800S is discontinued. The exact drop-in replacement is the SAID200X800S. It matches the ISO 15552 interface, 200mm bore, 800mm stroke, G3/4 port, and mounting hardware, while adding an upgraded piston seal.
Force is equal both ways: 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. Operating pressure is 0.15-1.0 MPa, proof pressure is 1.5 MPa, and speed is 30-500 mm/s. The G3/4 port and 50mm adjustable cushion at each end manage deceleration.
