This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X150, 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 SID200X150
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X150 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 150mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID200X150, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X150
The AirTAC SID200X150 is a discontinued ISO 15552 double-acting double-rod cylinder featuring a 200mm bore and 150mm stroke. A 40mm rod exits both ends, yielding identical push and pull force of 15080N at 0.5MPa, 21110N at 0.7MPa, and 27141N at 0.9MPa. It includes 50mm adjustable cushions at each end, a G3/4 port, and M36x2 rod threads. The direct replacement is the SAID200X150, which maintains the exact mounting interface, force, and porting.
Because the piston has rods on both faces, the effective area is identical in both directions, preventing snap-through on heavy presses and allowing the back rod to drive a second tool. The SAID upgrade uses a two-piece Y-shaped piston seal for lower start-up pressure and longer life. This non-magnetic SKU cannot accept switches, and it will not hold loads without air; use an external rod lock or SAIL variant for holding.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID200X150 Is Used
Equal-Force Pressing
Provides identical 15080N push and pull force at 0.5MPa, ensuring stable ejection in heavy-duty forming and stamping presses without snap-through risk.
Dual-Tool Transfer
The extending back rod drives a secondary mechanism or gripper simultaneously, synchronizing two material handling actions from one 200mm bore cylinder.
Anti-Rotation Lifting
Dual 40mm rods prevent mechanical twist during high-tonnage vertical elevation, guiding heavy pallets or machinery components smoothly up to 769kg.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X150 with the SAID200X150
To replace the discontinued SID200X150, use the SAID200X150 direct: it matches the 200mm bore, 150mm stroke, 15080N equal-both-ways force, G3/4 port, and ISO 15552 mounting. When sizing both ways, verify if a neighbouring bore like 160mm (9425N @0.5MPa) is sufficient or if the full 200mm is required. Choose a double-rod cylinder when you need equal force in both directions, anti-rotation stability, or a back rod to mount a sensor cam. Reuse FA, LB, or TC mounts. This SKU lacks the -S magnet, so it cannot support sensing. For strokes of 300mm or longer, account for side-load deflection. Because air cushions only decelerate, use an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X150
- ✓ 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 SID200X150 FAQ
Yes, the SID200X150 is discontinued. The direct replacement is the SAID200X150, which shares the same ISO 15552 interface, 200mm bore, 150mm stroke, G3/4 port, and 15080N equal-both-ways force. The SAI family also adds an upgraded two-piece Y-shaped piston seal for longer life.
Force is equal both ways: 15080N at 0.5MPa, 21110N at 0.7MPa, and 27141N at 0.9MPa. The air port is G3/4, the rod thread is M36x2, and it features 50mm adjustable cushions. It operates at 0.15-1.0MPa and runs at 30-500mm/s.
