About the Airtac SAID32 Double Rod Cylinder SAID32X85S
The AirTAC SAID32X85-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a built-in magnet for position sensing. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 483 N of force in both directions at 0.7 MPa. The 85 mm stroke is a made-to-order non-standard length, ensuring tailored motion for specialized assemblies.
This unit includes a standard carbon steel rod and PT tapered port threads. The extruded aluminum barrel provides sensor grooves on both sides, allowing you to mount a CMSE reed switch or DMSE solid-state sensor along either rail. The twin rods provide inherent anti-rotation guidance, while the rear rod end can simultaneously drive a secondary mechanism or position flag.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID32 Double Rod Cylinder SAID32X85S Is Used
Symmetric Force Transfer
Drives shuttles or transfer clamps where the return stroke must match the extend stroke in both speed and 483 N output force.
Dual-Side Tool Actuation
Mounts the primary workpiece on the front rod and a secondary cam or position flag on the rear rod for synchronized machine timing.
Anti-Rotation Slides
The twin through-rods guide the load against twist, ideal for linear slides carrying offset tooling heads.
Is the Airtac SAID32 Double Rod Cylinder SAID32X85S the Right Cylinder?
Choose this 32 mm bore when an application demands equal push and pull forces—such as 345 N at 0.5 MPa both ways—along with superior rotational stability compared to a single-rod SAI. If your mechanism requires higher thrust, stepping up to the 40 mm bore yields 528 N each way. Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. If the system loses air pressure, the cylinder will drift, requiring an external pilot-operated check valve or a SAIL lock cylinder for true position holding.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other ISO 15552 double-rod cylinders. To match this model for replacement, verify the 32 mm bore, 85 mm stroke, G1/8 port, PT thread type, and the -S magnet option. It supports the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAID32 Double Rod Cylinder SAID32X85S FAQ
Because the double-rod design subtracts the rod area on both sides of the piston, the extend and retract forces are equal. It generates 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa in both directions.
Yes. The SAID32X85-S is a profile cylinder dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 double-rod cylinders. Match the 32 mm bore, 85 mm stroke, and G1/8 porting.
