This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID125X190, 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 SID125X190
The AirTAC Airtac SID Series Double-Rod Cylinder SID125X190 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 190mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID125X190, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID125X190
The AirTAC SID125X190 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This architecture ensures push and pull force are equal at 5734 N @0.5 MPa, 8028 N @0.7 MPa, and 10321 N @0.9 MPa. The bore is 125 mm, the piston rod is Ø32 mm with an M27x2 thread, and the air port is G1/2. This legacy SID model is discontinued and the direct replacement is the SAID125X190, matching the ISO 15552 interface, bore, stroke, and mounting.
The SAID family introduces an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and long life, plus SAIL and BSAI lock variants absent from the SI line. This non-magnetic SKU cannot take a sensor. Note that air cushions only decelerate near stroke end; for load holding on air loss, use an external rod lock.

Theoretical Output Force (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6136 N | 5734 N |
| 0.7 MPa | 8590 N | — |
| Max (@1.0 MPa) | 1251 kgf | |
The SAID125X190 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 SID125X190 Is Used
Dual-Tool Machining Station
Drives two opposing machining heads with equal push and pull force of 8028 N @0.7 MPa, maintaining precise alignment via the double-rod architecture.
Anti-Rotation Transfer Gate
Uses the twin rods exiting both ends to prevent mechanical twist during heavy product diversion on a 125 mm bore assembly line.
Symmetric Pallet Lift
Lifts platform loads vertically with a safe working capacity near 3440 N, relying on equal both-ways force for stable descent control.
Replacing the Airtac SID Series Double-Rod Cylinder SID125X190 with the SAID125X190
To replace the discontinued SID125X190, install the direct replacement SAID125X190, which retains the exact ISO 15552 mounting interface, G1/2 port, and equal both-ways force. If sizing neighboring bores, the 100 mm bore yields 3681 N @0.5 MPa and the 160 mm bore yields 9425 N @0.5 MPa, both equal in push and pull. A double-rod design is right when you need anti-rotation stability or must drive two tools simultaneously. Mounting options include FA, LB, and TC brackets. This SKU lacks the -S magnet and cannot accept a sensor. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. Because this cylinder cannot hold a load on air loss, choose the SAIL or BSAI lock variant if needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID125X190
- ✓ 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 SID125X190 FAQ
Yes, the SID125X190 is discontinued. The direct replacement is the SAID125X190, which matches the ISO 15552 interface, 125 mm bore, 190 mm stroke, G1/2 port, and equal both-ways force.
The G1/2 port bore delivers equal push and pull force of 5734 N @0.5 MPa, 8028 N @0.7 MPa, and 10321 N @0.9 MPa. It operates at 0.15-1.0 MPa with a 40 mm adjustable cushion at each end.
