About the Airtac SAID80 Double Rod Cylinder SAID80BX125
The AirTAC SAID80X125 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 25mm rod exiting both end covers. Because the piston area is symmetrical, it generates exactly 2268N of thrust and retraction force at 0.5MPa, ensuring perfectly balanced motion for demanding transfer tasks.
This specific configuration utilizes a SUS304 stainless steel rod for superior corrosion resistance, alongside PT tapered port threads. The extruded aluminum barrel includes dual sensor grooves, allowing you to mount position flags on the rear rod for secondary mechanism tracking without external brackets.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX125 Is Used
Symmetric Force Transfer
Drives heavy workpiece shuttles where the 2268N both-way force prevents stalling during bidirectional indexing on machining centers.
Anti-Rotation Slides
Uses the twin-rod geometry to guide vertical lifting slides without twisting, eliminating the need for bulky external linear bearings.
Rear-Rod Cam Actuation
Mounts a cam or limit flag on the protruding rear rod to mechanically trigger secondary processes while the front rod performs the primary work.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX125 the Right Cylinder?
Select this 80mm bore when an application demands identical push and pull dynamics, stepping up from the 50mm bore (which provides 825N both ways at 0.5MPa) to handle heavier symmetric loads. A twin-rod design is preferred over a single-rod SAI when you need inherent anti-rotation guidance or must drive a cam from the rear side. Note that the adjustable air cushions only decelerate the piston near stroke end; if the air supply drops, the cylinder will drift, so use a SAIL lock or external pilot-operated check valve for position holding.
To match this exact configuration for a drop-in replacement, specify an 80mm bore, 125mm stroke, PT port threads, SUS304 rod material, and your desired mounting accessory from the SAID subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAID80BX125 FAQ
Because the double-rod design creates equal piston areas on both sides, the SAID80X125 provides 2268N of force in both extend and retract directions at 0.5MPa, scaling to 3175N at 0.7MPa.
Yes, the SAID80X125 is dimensionally interchangeable per ISO 15552. You can drop it in for other ISO 15552 double-rod cylinders, but ensure you use the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) as FB or CA styles are single-rod only.
