This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X175, 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 SID200X175
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X175 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 175mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID200X175, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X175
The AirTAC SID200X175 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal at 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. This SKU is discontinued and is replaced by the direct replacement SAID200X175, which retains the exact 200mm bore, 175mm stroke, G3/4 port, and mounting interface. The SAI replacement upgrades the piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life.
Because both faces use the rod-side area, the equal force prevents rod deflection during reversal, and the back rod can drive a second tool. Note this SKU has no -S magnet and cannot take a sensor. A plain cylinder does not hold loads on air loss; the 50mm adjustable cushion only decelerates near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID200X175 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAID200X175 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 SID200X175 Is Used
Tandem Press Drive
Uses the equal 27141 N @0.9 MPa force both ways to drive two opposing forming tools simultaneously on a single 200mm bore ISO 15552 interface.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X175 with the SAID200X175
To replace the discontinued SID200X175, install the direct replacement SAID200X175, matching the ISO 15552 interface, M36x2 rod thread, and G3/4 port. Size both ways using the equal-both-ways force: 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. If you need less force, step down to a 160mm bore (9425 N @0.5 MPa); if you need more, confirm from datasheet as 200mm is the largest. Choose a double-rod design when you need anti-rotation stability or to drive two tools. Mounting options include Basic, FA, LB, and TC. Select the -S magnet option if you need sensing, as this no-S SKU cannot take a switch. For stroke lengths >=300mm, verify side-load limits to prevent guide wear. Speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X175
- ✓ 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 SID200X175 FAQ
Yes, the AirTAC SID200X175 is discontinued. The direct replacement is the SAID200X175, which matches the ISO 15552 interface, 200mm bore, 175mm stroke, G3/4 port, and mounting. The SAI family also adds SAIL and BSAI lock variants.
The double-rod design provides equal force both ways: 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. The air port is G3/4, the rod thread is M36x2, and it has a 50mm adjustable cushion. It cannot hold loads on air loss without an external rod lock.
