About the Airtac SAID160 Double Rod Cylinder SAID160AX85S
The AirTAC SAID160X85-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 160mm bore and an 85mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extension and retraction, yielding an equal both-way force of 9425 N at 0.5 MPa. This symmetric output is ideal for mechanisms requiring identical push and pull dynamics.
Equipped with a magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic sensors along the dual extruded barrel grooves. The rods are crafted from SUS420J2 stainless steel (material code A) for superior corrosion resistance, and the G3/4 PT tapered ports ensure high airflow for heavy-duty actuation.

Where the Airtac SAID160 Double Rod Cylinder SAID160AX85S Is Used
Symmetric Force Transfer
Delivers 9425 N of thrust equally in both directions, ensuring perfectly balanced push and pull forces for heavy-duty press and forming operations.
Twin-Station Actuation
Uses the front rod to drive the primary workpiece while the rear rod simultaneously operates a secondary mechanism or valve, synchronizing two processes.
Anti-Rotation Guidance
The dual through-rods prevent piston rotation under high torque loads, providing stable and precise linear guidance for heavy material handling.
Is the Airtac SAID160 Double Rod Cylinder SAID160AX85S the Right Cylinder?
Choose this 160mm bore when a 100mm bore (providing 3681 N at 0.5 MPa) lacks sufficient thrust for your symmetric push-pull cycle. The twin-rod architecture is selected over a single-rod SAI when the application demands anti-rotation guidance or requires mounting a secondary cam and position flag on the rear rod extension.
For this 85mm stroke, side-load bending on the rod bearing is minimal, but heavy off-center loads should still use an external guide. Mounting options are limited to the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR variants found on single-rod models. Note that the adjustable air cushions at both ends decelerate the piston but do not lock the load; if position holding without air pressure is required, explore a BSAID clamp-lock cylinder.
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 SAID160AX85S FAQ
Because the rod area is subtracted on both sides, the push and pull forces are equal. This double-rod cylinder generates 9425 N at 0.5 MPa, 13194 N at 0.7 MPa, and 16964 N at 0.9 MPa in both directions.
Yes, the SAID160X85-S is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 double-rod profile cylinders, maintaining identical mounting interface dimensions.
