About the Airtac SAID32 Double Rod Cylinder SAID32X280
The AirTAC SAID32X280 is a double-acting, double-rod ISO 15552 profile cylinder with a 32 mm bore and 280 mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 345 N of force in both directions at 0.5 MPa. It operates at speeds of 30-800 mm/s and uses G1/8 PT ports.
This through-rod design allows you to mount the primary workpiece on one end and a position flag or cam on the rear rod for dual-side sensing. The extruded aluminum barrel features sensor grooves on both sides, and the standard carbon steel rod is paired with adjustable air cushions at both ends to manage end-of-stroke impact.

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 SAID32X280 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the 345 N push and pull forces must be perfectly matched, ensuring consistent cycle times in both directions.
Anti-Rotation Slides
Uses the twin-rod guidance to prevent mechanical twist during vertical lifting, keeping the load stable without needing an external linear rail.
Through-Rod Sensing
Actuates a part on the front stroke while the rear rod extension directly trips an external mechanical limit switch for precise end-position feedback.
Is the Airtac SAID32 Double Rod Cylinder SAID32X280 the Right Cylinder?
Choose the SAID32X280 when an application requires equal push and pull forces alongside anti-rotation stability that a single-rod SAI cannot provide. If you need higher thrust, stepping up to the 40 mm bore raises the both-way force to 528 N at 0.5 MPa. This model lacks a magnet, so position sensing requires external flags mounted to the rear rod. For direct replacements, verify the ISO 15552 mounting interface, the 280 mm stroke, and the G1/8 port size.
At 280 mm of stroke, the unsupported piston rod is subject to bending and side-load stress under heavy offset loads. Implementing an external linear guide is recommended to prevent premature rod-bearing wear. Note that the adjustable cushions only decelerate the piston near stroke end; they do not hold a load. If the system must maintain position after air loss, use a SAIL lock cylinder or an external pilot-operated check valve. SAID supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR.

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 SAID32X280 FAQ
Because the double-rod design occupies area on both sides of the piston, the extend and retract forces are equal. It generates 345 N both ways at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa.
Yes, the SAID32X280 is dimensionally interchangeable per ISO 15552 profile cylinder standards. You can use it as a direct replacement for other ISO 15552 double-rod cylinders with matching 32 mm bore and 280 mm stroke specifications.
