This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X125S, 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 SID32X125S
The AirTAC SID Series Double-Rod Cylinder SID32X125S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 125mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X125S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X125S
The AirTAC SID32X125S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal push and pull force on the rod-side area (345 N @0.5 MPa). This model is discontinued; the direct replacement is the SAID32X125S. It shares the exact 32mm bore, 125mm stroke, G1/8 port, M10x1.25 thread, and ISO 15552 mounting interface, while the SAI family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.
With a 27mm adjustable cushion at each end and a speed range of 30-800 mm/s, the design allows the back rod to carry a sensor cam for -S magnet switches (legacy CS1-B/DS1-B). Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAID32X125S 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 SID32X125S Is Used
Synchronized Gripper Actuation
Drives opposing gripper jaws simultaneously from a single piston, using the equal both-ways force to ensure perfectly balanced clamping pressure on delicate parts.
Dual-Side Transfer Pusher
Mounts a pusher blade on the front rod and a sensor cam on the back rod, allowing external position tracking without interfering with the primary work area.
Anti-Rotation Pick and Place
The twin-rod architecture inherently resists torsional twist, maintaining precise vertical alignment when lifting and placing 18 kg electronic component trays.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X125S with the SAID32X125S
To replace the discontinued SID32X125S, specify the SAID32X125S, which reuses the exact ISO 15552 mounting interface (Basic, FA, LB, TC) without bracket changes. Because force is equal both ways, size it by checking the 345 N @0.5 MPa rating against your load; if more force is needed, step up to the 40mm bore (528 N). A double rod is right when you need anti-rotation resistance or want to drive two tools from one piston. The -S suffix indicates a built-in magnet for position sensing. For this 125mm stroke, side-load is minimal, but for any stroke >=300mm, ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X125S
- ✓ 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 SID32X125S FAQ
Yes, the SID32X125S is discontinued. The direct replacement is the SAID32X125S, which matches the 32mm bore, 125mm stroke, G1/8 port, and ISO 15552 mounting, while adding an upgraded Y-shaped piston seal.
As a double-rod cylinder, force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The air port is G1/8, the rod thread is M10x1.25, and it features a 27mm adjustable cushion at each end.
