About the Airtac SAID32 Double Rod Cylinder SAID32X850S
The AirTAC SAID32X850-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and an 850mm stroke. Because the twin rods occupy both sides of the piston, the annular area is symmetrical, yielding an equal 483N of force in both extend and retract directions at 0.7MPa. This through-rod design is ideal for applications requiring dual-side guidance or rear-mounted position flags.
Equipped with a magnetic piston (-S), this unit triggers AirTAC CMSE reed and DMSE electronic sensors along the dual side grooves. The carbon steel rods thread M10x1.25, and the cylinder uses PT tapered ports. As an 850mm stroke exceeds the 32mm bore's 500mm standard limit, this is a non-standard, made-to-order configuration requiring rear-rod clearance.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
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 SAID32X850S Is Used
Extended Transfer Slides
Provides stable, long-stroke component transfer where the rear rod simultaneously drives a secondary mechanism without rotation.
Symmetric Force Actuation
Ensures identical push and pull forces for automated assemblies that require perfectly balanced bi-directional clamping.
Dual-Side Sensing Stations
Utilizes the rear rod protrusion to mount physical limit flags or drive secondary tooling alongside CMSE/DMSE sensor tracking.
Is the Airtac SAID32 Double Rod Cylinder SAID32X850S the Right Cylinder?
Select this non-standard 850mm stroke model when you need extended travel with equal push/pull forces (483N at 0.7MPa) and anti-rotation stability. If your application requires less force, stepping down is not an option below 32mm in this series, but stepping up to a 40mm bore provides 739N both ways. Choose the double-rod SAID over a single-rod SAI when you need to mount a secondary cam or sensor flag on the rear rod, or when symmetric load guiding is critical.
For an 850mm stroke, the unsupported carbon steel rod length increases susceptibility to bending under side loads; always use an external guide rail to prevent rod-bearing damage. This cylinder uses a G1/8 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. Note that air cushions only decelerate the piston near stroke end; they do not hold the load if air pressure is lost. For position holding, use an external pilot-operated check valve.

- ✓ 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 SAID32X850S FAQ
Because it is a double-rod cylinder, the effective piston area is identical in both directions. It provides an equal force of 345N at 0.5MPa, 483N at 0.7MPa, and 621N at 0.9MPa for both extending and retracting.
Yes, it is dimensionally interchangeable per ISO 15552 standards, serving as a direct replacement for other ISO 15552 profile double-rod cylinders. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and requires additional rear clearance for the through-rod.
