This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID125X10, 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 SID125X10
The AirTAC Airtac SID Series Double-Rod Cylinder SID125X10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 10mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID125X10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID125X10
The AirTAC SID125X10 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force remain equal at 5734 N @0.5 MPa, 8028 N @0.7 MPa, and 10321 N @0.9 MPa. This discontinued model features a 125mm bore, 10mm stroke, M27x2 rod thread, G1/2 port, and 40mm adjustable cushions. The direct replacement is the SAID125X10, matching the interface, force, and mounting.
The SAID upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a magnet (-S) for sensors. A plain cylinder drifts on air loss; cushions only decelerate, so use an external rod lock or SAIL/BSAI variant for held loads.

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 SAID125X10 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 SID125X10 Is Used
Multi-Tool Synchronization
Drives two independent work operations simultaneously from one piston, utilizing the equal push and pull force of 8028 N @0.7 MPa on both rod ends.
Symmetric Transfer Unit
Mounts via ISO 15552 TC brackets to push and pull pallets identically, benefiting from the 40mm adjustable cushions at each end for smooth deceleration.
Replacing the Airtac SID Series Double-Rod Cylinder SID125X10 with the SAID125X10
To replace the discontinued SID125X10, install the SAID125X10 direct, which preserves the ISO 15552 mounting interface, G1/2 port, and equal both ways force. Size both directions by checking neighboring bores: the 100mm bore yields 3681 N @0.5 MPa, and the 160mm bore yields 9425 N @0.5 MPa. A double-rod design is right when you need anti-rotation stability or must drive two tools. Reuse FA, LB, or TC mounts. Since this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. With a 10mm stroke, side-load is negligible, but for any stroke >=300mm, ensure guide alignment to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID125X10
- ✓ 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 SID125X10 FAQ
Yes, the SID125X10 is discontinued. The direct replacement is the SAID125X10, which shares the identical ISO 15552 interface, 125mm bore, 10mm stroke, G1/2 port, and mounting options.
As a double-rod cylinder, force is equal both ways: 5734 N @0.5 MPa, 8028 N @0.7 MPa, and 10321 N @0.9 MPa. The air port is G1/2, the rod thread is M27x2, and it operates at 30-500 mm/s.
