About the Airtac SAID50 Double Rod Cylinder SAID50X65
The AirTAC SAID50X65 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 65 mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on both sides, yielding a perfectly symmetric 825 N output at 0.5 MPa in both extend and retract directions.
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 includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting, while the PT tapered ports ensure a tight pneumatic seal.

Where the Airtac SAID50 Double Rod Cylinder SAID50X65 Is Used
Symmetric Force Transfer
Ideal for mechanisms requiring identical push and pull forces, such as alternating clamps or transfer arms where the 825 N output must remain constant in both directions.
Rear-Rod Cam Actuation
The protruding rear rod can drive a secondary cam or limit switch, allowing designers to trigger external pneumatic valves or mechanical signals simultaneously with the main stroke.
Anti-Rotation Slides
The dual carbon steel rods provide superior guidance and resist torsional deflection, making it perfect for lifting heavy parallel plates without binding or twisting.
Is the Airtac SAID50 Double Rod Cylinder SAID50X65 the Right Cylinder?
Select this 50 mm bore model when an application requires equal push and pull forces (825 N at 0.5 MPa) alongside anti-rotation stability. If your mechanism needs less force, the 40 mm bore offers 528 N; if you need more clamping power, the 63 mm bore provides 1402 N. The twin-rod architecture inherently resists torsional loads better than a single-rod SAI cylinder, though an external guide is still recommended for heavy lateral loads.
This model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR accessories. It is dimensionally interchangeable per ISO 15552 standards. Note that the adjustable air cushions only decelerate the piston near stroke end; this cylinder will drift if air pressure is lost, so use a SAIL or BSAID lock cylinder if position holding is required.
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 SAID50X65 FAQ
The SAID50X65 provides an equal force of 825 N in both the extend and retract directions at 0.5 MPa. This symmetric output is because the rod occupies both sides of the piston, making the effective annulus area identical both ways.
Yes, it is dimensionally interchangeable with ISO 15552 profile cylinders. However, the SAID double-rod series uses a specific mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) and does not support FB, CA, CB, or CR mounts due to the rear rod protrusion.
