About the Airtac SAID50 Double Rod Cylinder SAID50X35
The AirTAC SAID50X35 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 35mm stroke. Because a carbon steel rod exits both end covers, the effective piston area is identical in both directions, yielding an equal extend and retract force of 825N at 0.5 MPa. This symmetric force profile is essential for applications requiring perfectly balanced push and pull dynamics.
Beyond equal thrust, the twin-rod architecture provides superior anti-rotation guidance for the load. The rear rod extension can be utilized to mount a cam or secondary position flag, while the extruded aluminum barrel incorporates dual-side sensor grooves. Note that without a specific magnet suffix, this configuration does not support position sensing.

Where the Airtac SAID50 Double Rod Cylinder SAID50X35 Is Used
Symmetric Force Transfer
Delivers identical 825N push and pull forces at 0.5 MPa, ideal for shuttle mechanisms requiring perfectly balanced kinetic energy in both travel directions.
Anti-Rotation Slides
The twin 16mm carbon steel rods exiting both covers provide high torsional rigidity, preventing load rotation without needing external guide rails.
Rear-Rod Cam Actuation
The protruding rear rod end can drive a secondary mechanism or cam, allowing designers to trigger mechanical switches or secondary valves from the opposite cylinder end.
Is the Airtac SAID50 Double Rod Cylinder SAID50X35 the Right Cylinder?
Select this 50mm bore model when an application demands equal bidirectional force and high torsional resistance, stepping up from the 40mm bore (528N at 0.5 MPa) for heavier symmetric loads, or down to the 32mm bore (345N) for lighter duties. The PT-threaded G1/4 port and 16mm rod thread provide robust mechanical connections for the 35mm stroke. Mounting options include the reduced SAID set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR accessories found on single-rod variants.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders for drop-in replacements. Keep in mind that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If position holding without live air pressure is required, consider an external rod lock or a SAIL/BSAID variant.
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 SAID50 Double Rod Cylinder SAID50X35 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the output force is equal in both directions. It provides 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID50X35 is a profile cylinder built to ISO 15552 mounting interface dimensions, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a PT G1/4 port and supports the standard SAID mounting accessory set.
