This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X175S, 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 SID100X175S
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X175S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 175mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X175S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X175S
The AirTAC SID100X175S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, making push and pull force equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. This 100 mm bore uses a 25 mm rod, M20x1.5 thread, G1/2 port, and 36 mm adjustable cushions. The SID line is discontinued; the direct replacement is the SAID100X175S, reusing the same ISO 15552 mounting interface without changes.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. 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 (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 SAID100X175S 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 SID100X175S Is Used
Equal-Force Stamping
Drives a stamping die where the return stroke must match the forward stroke force, utilizing the 5153 N @0.7 MPa capacity for consistent bidirectional pressure.
Dual-End Transfer
Uses the rod protruding from both ends to push a workpiece onto one conveyor while simultaneously retracting a part from another, saving cycle time.
Anti-Rotation Guiding
Employs the twin rods to resist torsional twist during precision material handling, ensuring the payload stays perfectly aligned without external guides.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X175S with the SAID100X175S
To replace the discontinued SID100X175S, install the direct replacement SAID100X175S, matching the 175 mm stroke, 100 mm bore, G1/2 port, and FA/LB/TC mounts. Size both directions by equal force: if 5153 N @0.7 MPa is insufficient, step up to bore 125 (8028 N), or drop to bore 80 (3175 N). Choose a double-rod when you need anti-rotation stability or a back rod to carry a sensor cam. The -S magnet enables position sensing. For this 175 mm stroke side-load is low, but for strokes >=300 mm verify guide alignment to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X175S
- ✓ 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 SID100X175S FAQ
Yes, the SID100X175S is discontinued. The direct replacement is the SAID100X175S. It shares the identical ISO 15552 mounting interface, 100 mm bore, 175 mm stroke, G1/2 port, and equal-both-ways force, but adds an upgraded two Y-shaped one-way piston seal.
Because it is a double-rod cylinder, force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The air port is G1/2.
