This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAID200X800 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAID200X800 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 SID200X800
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X800 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 SAID200X800, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X800
The AirTAC SID200X800 is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends on one piston, making push and pull force equal at 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. It features a 200mm bore, 800mm stroke, G3/4 port, M36x2 rod thread, and 50mm adjustable cushions. The exact drop-in replacement is the SAID200X800, matching the interface, force, and mounting.
This SKU has no -S magnet and cannot take a sensor. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. Computed buyer insight: safe working load is ~9048 N (60% of the 15080 N @0.5 MPa figure), yielding a 769 kg vertical lift with a 2:1 margin. A plain cylinder drifts on air loss; cushions only decelerate, so use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID200X800 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAID200X800 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 SID200X800 Is Used
Dual-Tool Transfer
Drives two synchronized clamps from opposite rod ends to push and pull parts simultaneously through a machining station with equal 21110 N force.
Balanced Vertical Lift
Lifts a 769 kg platen with a 2:1 margin using the equal both-ways rod-side area, preventing the uneven acceleration typical of single-rod cylinders.
Anti-Rotation Indexing
Moves a heavy 1500mm-stroke carriage on a packaging line, using the twin rods to resist torsional twist and maintain precise parallel tracking.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X800 with the SAID200X800
Replace the discontinued SID200X800 directly with the SAID200X800, reusing your existing ISO 15552 FA, LB, or TC mounts. Size both ways by checking equal force: if 21110 N @0.7 MPa is excessive, step down to a 160mm bore, or step up if higher force is needed. Choose a double-rod cylinder when you need anti-rotation stability or need to drive two tools from one piston. Because this non-magnetic SKU cannot carry a switch, add external sensors if detection is required. For the 800mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X800
- ✓ 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 SID200X800 FAQ
Yes, the SID200X800 is discontinued. The exact drop-in replacement is the SAID200X800. It shares the same ISO 15552 mounting interface, 200mm bore, 800mm stroke, G3/4 port, and equal both-ways force. The SAI family also adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
Because it is a double-rod cylinder, 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 with 50mm adjustable cushions at each end. Speed is 30-500 mm/s. Note that air cushions only decelerate near stroke end; they do not hold loads on air loss.
