About the Airtac SAID80 Double Rod Cylinder SAID80X65S
The AirTAC SAID80X65-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80 mm bore and 65 mm stroke. Because a carbon steel rod extends from both end covers, the annulus area is identical on both sides, yielding equal push and pull forces of 2268 N at 0.5 MPa and 3175 N at 0.7 MPa. The built-in magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves.
This through-rod design allows you to mount the primary workpiece on one end and a secondary cam, limit flag, or guidance tool on the rear rod. The twin-rod configuration provides superior anti-rotation stability compared to a single-rod SAI cylinder. Adjustable air cushions at both ends decelerate the piston over a 36 mm stroke, and the PT G3/8 port ensures high flow for rapid cycling.

Where the Airtac SAID80 Double Rod Cylinder SAID80X65S Is Used
Symmetric-Force Transfer
Drives a shuttle or transfer mechanism where the equal 2268 N push and pull forces at 0.5 MPa prevent asymmetric acceleration or stalling.
Anti-Rotation Slides
Guides a machining slide or workhead with high torsional resistance using the twin-rod design, preventing deflection during cutting operations.
Through-Rod Sensing
Actuates a primary clamp on the front rod while using the rear rod extension to trigger a DMSE electronic position switch for sequence verification.
Is the Airtac SAID80 Double Rod Cylinder SAID80X65S the Right Cylinder?
Choose this 80 mm bore when an application demands symmetric force and dual-side actuation, delivering 2268 N both ways at 0.5 MPa. If your mechanism requires less force, step down to the 63 mm bore (1402 N); if you need more push or pull, the 100 mm bore offers 3681 N. The double-rod architecture is specifically selected over a single-rod SAI when the machine design requires rear-rod sensing, twin-station driving, or strict anti-rotation guidance.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 double-rod profile cylinders. Ensure you specify the PT G3/8 port thread, your required mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2), and the -S magnet option for CMSE/DMSE sensors. Note that a plain SAID does not hold a load when air pressure is lost; for fail-safe holding, consider an SAIL lock, BSAID clamp-lock, or an external rod lock.
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 SAID80 Double Rod Cylinder SAID80X65S FAQ
Because the rod occupies both sides of the piston, the extend and retract forces are equal. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa in both directions.
Yes. The SAID80X65-S is a profile cylinder dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders, though it uses a PT G3/8 port and supports AirTAC CMSE/DMSE sensors.
