This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X150, 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 SID100X150
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X150 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X150, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X150
The AirTAC SID100X150 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal force in both directions at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It features a 100mm bore, 150mm stroke, G1/2 air port, M20x1.5 rod thread, and 36mm adjustable cushions. This SID model is discontinued; the direct replacement is the SAID100X150, sharing the same interface and force.
The SAID upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. Without a -S suffix, this SKU lacks a magnet and cannot mount reed switches. The double-rod design prevents rod rotation and lets the rear rod drive a second tool. Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAID100X150 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 SID100X150 Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously from a single piston, utilising the equal both-ways force to maintain perfectly balanced cutting pressure on both sides.
Anti-Rotation Transfer Unit
Moves a heavy workpiece down a line without rotational drift, using the dual-rod architecture to resist torsional side-load and maintain precise alignment.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X150 with the SAID100X150
To replace the discontinued SID100X150, install the direct replacement SAID100X150, which matches the ISO 15552 mounting interface, G1/2 port, and 150mm stroke. Size both directions by verifying the equal push/pull force of 5153 N @0.7 MPa is sufficient; if lower, check neighbouring bores like the 125mm. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools simultaneously. Reuse FA, LB, or TC mounts. For strokes of 300mm or longer, verify side-load limits to prevent guide wear. This non-magnetic SKU cannot use sensors; if tracking is needed, select an -S model.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X150
- ✓ 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 SID100X150 FAQ
Yes, the AirTAC SID100X150 is discontinued. The direct replacement is the SAID100X150. It shares the same ISO 15552 mounting interface, 100mm bore, 150mm stroke, G1/2 port, and equal both-ways force, while adding an upgraded two-piece Y-shaped piston seal.
Being a double-rod cylinder, push and pull force are equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The bore is 100mm with a G1/2 air port, M20x1.5 rod thread, 36mm adjustable cushions, and an operating speed of 30-800 mm/s.
