This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X175S, 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 SID200X175S
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X175S 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 SAID200X175S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X175S
The AirTAC SID200X175S is a discontinued 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. It features a 200mm bore, 40mm rod, M36x2 thread, G3/4 port, 50mm adjustable cushions, and a -S magnet for legacy CS1-B/DS1-B switches. The direct replacement is the SAID200X175S, which reuses the same interface, bore, stroke, and mounting.
The SAID upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life, alongside SAIL and BSAI lock variants absent from the SI line. Note that air cushions only decelerate near stroke end; a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID200X175S 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 SAID200X175S 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 SID200X175S Is Used
Dual-Tool Transfer
Drives two opposing tools simultaneously from a single piston, utilising the equal push and pull force of the 200mm bore for heavy material handling.
Anti-Rotation Press
The twin-rod architecture prevents mechanical rotation during high-tonnage pressing operations, maintaining precise vertical alignment without external guides.
Cam-Driven Sensing
Uses the extending back rod to carry a sensor cam, allowing external position tracking while keeping the primary working rod unobstructed for tooling.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X175S with the SAID200X175S
Replace the discontinued SID200X175S directly with the SAID200X175S, matching the 200mm bore, 175mm stroke, G3/4 port, and ISO 15552 mounting. Size both directions by equal force: 15080 N @0.5 MPa, 21110 N @0.7 MPa, 27141 N @0.9 MPa. If lower force is acceptable, neighbouring bores like 160mm offer 9425/13194/16964 N. Choose a double-rod when you need anti-rotation, a back rod to carry a sensor cam, or to drive two tools. Mounting options include Basic, FA, LB, and TC. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. 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 → SAID200X175S
- ✓ 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 SID200X175S FAQ
Yes, the SID200X175S is discontinued. The direct replacement is the SAID200X175S. It shares the same ISO 15552 mounting interface, 200mm bore, 175mm stroke, G3/4 port, and equal both-ways force, but uses an upgraded two Y-shaped one-way piston seal for longer life.
Force is equal both ways: 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. Operating pressure is 0.15-1.0 MPa. Speed is 30-500 mm/s. The cylinder has a 40mm rod, M36x2 thread, and 50mm adjustable cushions at each end.
