About the Airtac SAID32 Double Rod Cylinder SAID32X900S
The AirTAC SAID32X900-S is a double-acting, double-rod profile cylinder operating on the ISO 15552 mounting interface. Because a carbon steel rod exits both end covers, the annulus area is identical on each side. This yields exactly 483N of force in both extend and retract directions at 0.7 MPa, ensuring symmetric thrust and speed for your automation cycle.
Equipped with a magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual side grooves. As a made-to-order 900mm stroke exceeding the standard 500mm limit for this bore, it requires substantial rear-rod clearance. The rear protrusion is ideal for mounting a secondary cam or position flag to drive an external mechanism.

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 SAID32X900S Is Used
Symmetric Force Transfer
Drives a transfer carriage with identical 483N thrust and speed in both directions, ensuring perfectly timed cyclic motion without momentum imbalances.
Anti-Rotation Slides
The twin-rod geometry resists torsional twist on long 900mm strokes, keeping the workpiece rigidly guided without needing a separate external guide rod.
Through-Rod Sensing
Mounts a physical cam or flag on the rear rod protrusion to trigger external DMSE solid-state sensors or mechanical limit switches for redundant positioning.
Is the Airtac SAID32 Double Rod Cylinder SAID32X900S the Right Cylinder?
Select this twin-rod actuator when an application demands equal push/pull dynamics and anti-rotation guidance that a single-rod SAI cannot provide. If your project needs less force, stepping down is not an option in this footprint, but stepping up to a 40mm bore raises the bidirectional output to 739N at 0.7 MPa. At 900mm, the unsupported 12mm rod is highly susceptible to bending under side loads; always incorporate an external linear guide to protect the rod bearing and seals.
This cylinder is dimensionally interchangeable per ISO 15552 as a direct replacement for other double-rod profile cylinders. Specify PT tapered port threads, your required mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2), and the -S magnet. Note that adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If pressure is lost, the piston drifts, requiring a BSAID clamp-lock or external pilot-operated check valve for secure positioning.
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 SAID32 Double Rod Cylinder SAID32X900S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. It delivers 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa for both extend and retract strokes.
Yes, it shares the exact ISO 15552 mounting interface and dimensions, making it a direct replacement for comparable double-rod profile cylinders. Just ensure you have adequate rear clearance for the through-rod.
