About the Airtac SAID80 Double Rod Cylinder SAID80BX500S
The AirTAC SAID80X500-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 500 mm stroke and an 80 mm bore. Because a stainless steel SUS304 rod exits both end covers, the annular piston area is identical on extend and retract. This yields exactly 2268 N of force at 0.5 MPa in both directions, ensuring perfectly symmetric motion for demanding transfer tasks.
Equipped with a piston magnet (-S), this variant directly supports rear-side position sensing using AirTAC CMSE reed or DMSE electronic solid-state switches seated in the dual-side barrel grooves. The rear rod extension is ideal for mounting a cam, secondary mechanism, or limit flag, while the PT-threaded G3/8 ports provide robust pneumatic flow for speeds up to 800 mm/s.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX500S Is Used
Symmetric Force Transfer
Drives overhead conveyor actuators where the matching 2268 N extend and retract forces prevent motor stall during bidirectional product shifting.
Anti-Rotation Slides
The twin SUS304 rods resist torsional twist across the 500 mm stroke, keeping precision machining slides perfectly aligned without external guides.
Dual-Side Tool Actuation
Mounts a primary workpiece clamp on the front rod and a secondary limit flag on the rear protruding rod to trigger DMSE electronic sensors simultaneously.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX500S the Right Cylinder?
Select this 80 mm bore model when an application strictly requires symmetric thrust and anti-rotation guidance that a single-rod SAI cannot provide. If your load demands less force, stepping down to the 63 mm bore yields 1402 N at 0.5 MPa, whereas moving up to the 100 mm bore provides 3681 N. This SAID80X500-S is dimensionally interchangeable per ISO 15552, offering a drop-in replacement for other standard profile cylinders.
For a 500 mm stroke, the extended rod length increases side-load leverage on the internal rod bearing; utilizing an external guide rail is strongly recommended to prevent premature wear. Remember that a plain SAID does not hold a load when air is exhausted or the valve is centered—the adjustable air cushions only decelerate the piston near stroke end, so add a SAIL lock or BSAID clamp-lock if position holding is required. Available mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAID80BX500S FAQ
Because the double-rod design subtracts the rod area on both sides of the piston, the force is identical in both directions. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, the SAID80X500-S is a profile cylinder built to ISO 15552 mounting interface dimensions, making it a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.
