About the Airtac SAID80 Double Rod Cylinder SAID80BX550
The AirTAC SAID80X550 is a double-acting, double-rod ISO 15552 profile cylinder engineered for tasks requiring equal force and speed in both directions. Because a rod extends from both end covers, the annulus area is identical on extend and retract, yielding a consistent 2268 N of thrust each way at 0.5 MPa. The extended 550 mm stroke is a standard made-to-order length for this bore, meaning the overall physical envelope is significantly longer than a typical single-rod unit to accommodate the rear protrusion.
This specific configuration features SUS304 stainless steel rods (material code B), providing excellent corrosion resistance for harsh or washdown environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting, and adjustable air cushions at both ends absorb kinetic energy near stroke limits. It operates at pressures from 0.15-1.0 MPa with PT tapered port threads.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX550 Is Used
Symmetric Force Transfer
Drives a workpiece from one end while the opposing rear rod moves an identical secondary load, utilizing the matched 2268 N thrust in both directions.
Anti-Rotation Slides
The twin-rod geometry prevents piston rotation during the 550 mm traverse, maintaining precise angular alignment for machining or indexing fixtures.
Through-Rod Sensing
Mounts a physical cam or limit flag on the rear SUS304 rod end to trigger external mechanical switches, avoiding internal sensor grooves entirely.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX550 the Right Cylinder?
Selecting the SAID80X550 is ideal when your mechanism requires twin-station actuation, a rear cam for position feedback, or superior anti-rotation guidance compared to a single-rod SAI. If your application needs less force, stepping down to the 63 mm bore offers 1402 N each way at 0.5 MPa; stepping up to the 100 mm bore provides 3681 N. This 80 mm bore utilizes a G3/8 port and operates at speeds of 30-800 mm/s.
Because this model features a 550 mm stroke, the long unsupported rod span increases the risk of side-load bending and premature bearing wear; an external guide rail should be used to support heavy off-center loads. Note that the adjustable cushions only decelerate the piston near the end caps and 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 variant. Mounting options are limited to the SAID subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAID80BX550 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It delivers 2268 N of force in both extend and retract directions at 0.5 MPa, and 3175 N at 0.7 MPa.
Yes, the SAID80X550 is dimensionally interchangeable per ISO 15552 mounting interface dimensions. It serves as a drop-in replacement for other ISO 15552 profile cylinders, utilizing the standard Basic, FA, LB, and TC mounting accessories.
