About the Airtac SAID160 Double Rod Cylinder SAID160BX20
The AirTAC SAID160X20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 160 mm bore and a 20 mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract, yielding an equal thrust of 9425 N in both directions at 0.5 MPa. This through-rod architecture is ideal for applications requiring dual-side guidance, anti-rotation, or mounting a secondary mechanism and a position flag on the rear rod.
This specific configuration incorporates a SUS304 stainless steel rod (material code B) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Adjustable air cushions at both ends decelerate the piston near stroke extremes, though this cylinder does not hold position on loss of air pressure without an external check valve.

Where the Airtac SAID160 Double Rod Cylinder SAID160BX20 Is Used
Symmetric Force Transfer
Drives heavy loads with identical push and pull thrust, ensuring perfectly balanced force distribution for precision pressing and forming operations.
Anti-Rotation Slides
The twin-rod design prevents piston rotation, providing strict linear guidance for heavy-duty sliding gates and heavy material handling stages.
Twin-Station Actuation
Mounts a primary workpiece on the front rod and a secondary cam or limit flag on the rear rod to operate two synchronized workstations simultaneously.
Is the Airtac SAID160 Double Rod Cylinder SAID160BX20 the Right Cylinder?
Selecting the SAID160X20 is optimal when a mechanism demands equal push and pull forces alongside high torsional stability. If your application requires less force, stepping down to the 125 mm bore reduces the both-way output to 5734 N at 0.5 MPa. Conversely, if you need maximum thrust, the 200 mm bore variant offers 15079 N each way. The 20 mm stroke on this 160 mm bore provides a compact motion profile while maintaining the heavy-duty rod diameter of 40 mm.
This model uses PT ports and supports the reduced SAID mounting accessory set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR mounts found on single-rod SAI cylinders. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Since no magnet is specified, position sensing requires external physical switches or a custom -S variant to use AirTAC CMSE reed or DMSE electronic sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID160 Double Rod Cylinder SAID160BX20 FAQ
The double-rod design provides equal force in both directions. It delivers 9425 N at 0.5 MPa, 13194 N at 0.7 MPa, and 16964 N at 0.9 MPa.
It is dimensionally interchangeable per ISO 15552 mounting interfaces. It does not hold position if air pressure is lost; for load holding, consider a SAIL lock, BSAID clamp-lock, or an external pilot-operated check valve.
