This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X150, 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 SID80X150
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X150 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X150, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X150
The AirTAC SID80X150 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal push and pull force of 2268 N at 0.5 MPa. This SKU lacks a magnet (-S) and cannot accept reed switches. It features a 25 mm rod, M20x1.5 thread, 36 mm cushions, G3/8 port, and 30-800 mm/s speed.
This SID model is discontinued; the direct replacement is the SAID80X150 (same bore, stroke, force, port, and ISO 15552 mounting). The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. A double rod prevents rotation and lets the back rod drive a second tool. The cushion only decelerates; use SAIL/BSAI or an external rod lock to hold loads.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAID80X150 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 SID80X150 Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously from a single piston, utilizing the equal both-ways force to ensure perfectly synchronized part clamping and milling operations.
Anti-Rotation Transfer Gate
Uses the twin-rod architecture to prevent mechanical rotation during rapid part diversion on a conveyor line, maintaining precise alignment without external linear guides.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X150 with the SAID80X150
Replace the discontinued SID80X150 directly with the SAID80X150, reusing your FA, LB, or TC ISO 15552 mounts. Size both directions by equal force: if 2268 N at 0.5 MPa is insufficient, step up to the 100 mm bore (3681 N), or drop to the 63 mm bore (1402 N). Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one piston. This non-magnetic SKU cannot support sensors. For this 150 mm stroke, side-load is minimal, but for strokes >=300 mm ensure guide alignment to prevent binding. Remember, air cushions only decelerate; they do not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X150
- ✓ 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 SID80X150 FAQ
Yes, the SID80X150 is discontinued. The direct replacement is the SAID80X150, which matches the 80 mm bore, 150 mm stroke, G3/8 port, and ISO 15552 mounting interface. The SAID family also features an upgraded two Y-shaped one-way piston seal for longer life and lower start-up pressure.
Because it is a double-rod cylinder, force is equal both ways: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It operates at 30-800 mm/s, has a 25 mm rod with an M20x1.5 thread, and features 36 mm adjustable air cushions at each end.
