This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X175S, 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 SID63X175S
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X175S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 175mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X175S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X175S
The AirTAC SID63X175S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, making push and pull force equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This SID model is discontinued and the direct replacement is the SAID63X175S, retaining the 63mm bore, 175mm stroke, G3/8 port, and M16x1.5 rod thread. The SAI successor uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
Because both faces use the rod-side area, the back rod can carry a sensor cam or drive a second tool while resisting rotation. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that air cushions only decelerate near stroke end; a plain cylinder drifts on air loss, so use an external rod lock or SAIL/BSAI variant for held loads.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAID63X175S 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 SID63X175S Is Used
Synchronized Tool Driving
Drives two opposing mechanisms simultaneously from a single piston, utilizing the equal push and pull force of the dual rods to maintain perfect timing.
Anti-Rotation Transfer
Transfers workpieces along a linear path without rotational drift, leveraging the inherent anti-rotation properties of the double-rod assembly.
Dual-End Sensing
Uses the rear exiting rod to carry a sensor cam, allowing external position tracking while the front rod performs the primary work stroke.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X175S with the SAID63X175S
To replace the discontinued SID63X175S, install the direct replacement SAID63X175S, which matches the ISO 15552 mounting interface, 175mm stroke, and equal both-ways force. When sizing both ways, verify the 1402 N @0.5 MPa output fits your load, or step to neighbouring bores (50mm or 80mm) to scale force symmetrically. Choose a double-rod configuration when you need anti-rotation stability or want to drive two tools from one piston. Mounting options include Basic, FA, LB, and TC styles. The -S magnet enables position sensing, and for stroke lengths of 300mm or greater, carefully manage side-load alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X175S
- ✓ 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 SID63X175S FAQ
Yes, the SID63X175S is discontinued. The direct replacement is the SAID63X175S, which shares the same ISO 15552 interface, bore, stroke, G3/8 port, and equal both-ways force.
Force is equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The bore dictates a G3/8 air port, M16x1.5 rod thread, and 30mm adjustable cushions at each end.
