This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X200S, 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 SID160X200S
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X200S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X200S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X200S
The AirTAC SID160X200S is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal force both ways: 9425 N at 0.5 MPa, 13194 N at 0.7 MPa, and 16964 N at 0.9 MPa. It features a 160 mm bore, a 40 mm rod, M36x2 rod threads, and a G3/4 air port. The direct replacement is the SAID160X200S, sharing the same mounting interface, bore, stroke, and porting.
The SAI upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note that air cushions only decelerate; use an external rod lock or SAIL/BSAI variant for load holding on air loss.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAID160X200S 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 SID160X200S Is Used
Equal-Force Pressing
Drives a double-ended tooling station where the 9425 N equal push and pull force at 0.5 MPa is required for both the extension and retraction work strokes.
Symmetrical Transfer
Shifts pallets from a central conveyor lane using both rod ends to push and pull loads simultaneously without force mismatch.
Cam-Driven Gauging
Uses the rear exiting rod to carry a sensor cam for mid-stroke position feedback while the front rod performs the measurement actuation.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X200S with the SAID160X200S
To replace the discontinued SID160X200S, specify the SAID160X200S, which provides a direct ISO 15552 direct fit with identical 160 mm bore, 200 mm stroke, G3/4 port, and 9425 N equal-both-ways force at 0.5 MPa. When sizing both ways, verify if a neighboring bore (like 125 mm with 5734 N or 200 mm with 15080 N at 0.5 MPa) better suits your force requirements, but the 160 mm bore yields 13194 N at 0.7 MPa. A double-rod design is correct when you need equal push/pull force, anti-rotation stability, or a back rod to carry a sensor cam. Reuse FA, LB, or TC mounts, and select the -S magnet option for switch sensing. For strokes >=300 mm, ensure adequate side-load guidance to prevent rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X200S
- ✓ 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 SID160X200S FAQ
Yes, the SID160X200S is discontinued. The direct replacement is the SAID160X200S, which matches the ISO 15552 mounting interface, 160 mm bore, 200 mm stroke, G3/4 port, and equal-both-ways force.
The SID160X200S features a G3/4 air port and delivers equal force both ways: 9425 N at 0.5 MPa, 13194 N at 0.7 MPa, and 16964 N at 0.9 MPa. It operates at 30-500 mm/s with a 50 mm adjustable cushion at each end.
