This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X175, 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 SID100X175
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X175 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 SAID100X175, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X175
The AirTAC SID100X175 is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends on one piston. Both faces use the rod-side area, meaning push and pull force are equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It features a 100mm bore, 175mm stroke, 25mm piston rod, M20x1.5 rod-end thread, G1/2 air port, and 36mm adjustable air cushions at each end. The direct replacement is the SAID100X175, matching the interface, bore, stroke, force, port, and mounting.
Because this SKU lacks the -S magnet, it cannot take a magnetic switch. The SAI replacement upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. A plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end. For held loads use an external rod lock or SAIL/BSAI variant. The back rod can drive a second tool or carry a sensor cam.

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 SAID100X175 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 SID100X175 Is Used
Dual-Station Conveyor Transfer
Drives opposing pusher arms simultaneously from both rod ends to shift workpieces between parallel conveyor lanes with equal force.
Anti-Rotation Forming Press
Uses the twin-rod architecture to prevent piston rotation during high-precision metal forming, maintaining strict tool alignment.
Symmetric Pallet Lift Stop
Extends a physical stop blade from the rear rod while the front rod actuates a secondary latch, synchronizing two actions in one stroke.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X175 with the SAID100X175
Replace the discontinued SID100X175 directly with the SAID100X175, reusing your existing ISO 15552 FA, LB, or TC mounting hardware without machining. Size both ways by checking the equal push/pull force against your load; if 6626 N @0.9 MPa is insufficient, step up to the 125mm bore, or drop to 80mm if overspecified. A double-rod design is right when you need anti-rotation resistance or must drive two tools from one piston. This non-magnetic SKU cannot take a sensor. For this 175mm stroke side-load is minimal, but for strokes >=300mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X175
- ✓ 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 SID100X175 FAQ
Yes, the SID100X175 is discontinued. The direct replacement is the SAID100X175, which matches the ISO 15552 mounting interface, 100mm bore, 175mm stroke, G1/2 port, and equal both-ways force.
Force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The fixed air port is G1/2. It operates at 0.15-1.0 MPa with a 36mm adjustable cushion at each end.
