About the Airtac SAID80 Double Rod Cylinder SAID80BX135
The AirTAC SAID80X135 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 135mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is symmetrical, yielding an equal push and pull force of 2268 N at 0.5 MPa in either direction.
This configuration uses a SUS304 stainless steel rod for superior corrosion resistance. The through-rod design allows you to mount a primary workpiece on the front and a position flag or cam on the rear, taking advantage of the dual-side sensor grooves for synchronized feedback.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX135 Is Used
Anti-Rotation Slides
The twin-rod architecture prevents piston twisting during extension, providing stable guidance for precision sliding mechanisms without external guides.
Symmetric Transfer
Delivers identical 2268 N force extending and retracting at 0.5 MPa, ensuring consistent speed and power for bidirectional material transfer.
Dual-Side Actuation
Drive a primary tool on the front rod while utilizing the rear rod protrusion to operate a secondary mechanism or mount a limit flag.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX135 the Right Cylinder?
Select this 80mm bore when an application demands symmetric thrust and high anti-rotation resistance that a single-rod SAI cannot provide. If your load requires less force, stepping down to the 63mm bore offers 1402 N both ways at 0.5 MPa; if you need more, the 100mm bore provides 3681 N. For this 135mm stroke, side-load stress on the rod bearing is moderate, but external guidance is recommended if moving heavy off-center loads.
This model features PT tapered ports and a SUS304 stainless steel rod. It does not include a magnet; adding the -S suffix enables CMSE reed and DMSE electronic sensor tracking. Note that the adjustable air cushions only decelerate the piston near stroke end and do not hold the load if air pressure is lost. For drop-in replacements, it shares the exact ISO 15552 mounting interface and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories.
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 SAID80BX135 FAQ
Because it is a double-rod cylinder, the effective piston area is identical in both directions. It provides an equal force of 2268 N on extend and retract at 0.5 MPa, and 3175 N at 0.7 MPa.
Yes, the SAID80X135 is dimensionally interchangeable per ISO 15552 standards. It uses the same mounting footprint and accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) as comparable profile cylinders, though rear-rod clearance must be accounted for.
