About the Airtac SAID32 Double Rod Cylinder SAID32X550S
The AirTAC SAID32X550-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 550mm stroke. Because the twin rods occupy both piston sides, the annulus area is identical in both directions, yielding exactly 483N of force at 0.7 MPa on extend and retract alike. This 550mm stroke is a made-to-order non-standard length, meaning the overall physical body is notably longer to accommodate the rear rod protruding through the back cover.
Equipped with a magnet for position sensing, this unit interfaces directly with AirTAC CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves. A single piston drives both the front and rear carbon-steel rods simultaneously. This allows you to mount the primary workpiece on one end and a secondary cam, position flag, or guidance mechanism on the opposite end, ensuring superior anti-rotation stability compared to a single-rod SAI.

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 SAID32X550S Is Used
Symmetric Force Transfer
Ideal for shuttle mechanisms requiring identical 483N push and pull forces at 0.7 MPa, ensuring perfectly balanced motion without speed discrepancies between extend and retract strokes.
Anti-Rotation Slides
The twin carbon-steel rods prevent piston rotation, providing precise linear guidance for lifting or pressing tools that cannot tolerate angular deflection during travel.
Dual-Side Actuation
Mount the primary tool on the front rod and a secondary cam or position flag on the rear rod to trigger AirTAC DMSE solid-state sensors from the opposite end cover.
Is the Airtac SAID32 Double Rod Cylinder SAID32X550S the Right Cylinder?
Select this 32mm double-rod unit when an application strictly requires symmetric force and speed in both travel directions, providing 345N each way at 0.5 MPa. If your mechanism demands higher thrust, stepping up to the 40mm bore neighbor raises the bidirectional force to 528N at 0.5 MPa. Conversely, choosing a double-rod over a single-rod SAI is primarily driven by the need for dual-side actuation or rear-end sensing rather than raw push capacity. To match an existing ISO 15552 footprint, verify the PT G1/8 port, the 550mm stroke, and the appropriate mounting accessory from the SAID subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
Because this 550mm stroke exceeds the 32mm bore's 500mm standard maximum, it is manufactured as a special order. At this extended length, the unsupported rod mass creates a higher risk of rod-bearing bending and side-load stress. Always incorporate an external linear guide to support the load and prevent cylinder binding. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load if air pressure is lost. For position holding without live pressure, consider an external pilot-operated check valve or the BSAID clamp-lock series.

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 SAID32X550S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force 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.
The SAID32X550-S is dimensionally interchangeable per ISO 15552 profile standards, meaning it matches standard mounting footprints. However, it uses a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets found on single-rod variants.
