About the Airtac SAID100 Double Rod Cylinder SAID100BX300
The AirTAC SAID100X300 is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a SUS304 stainless steel rod out of both end covers, yielding equal extend and retract forces. Because the rod occupies both sides of the piston, the annulus area is identical in each direction, providing 3681 N of thrust and pull force at 0.5 MPa.
This symmetric design is ideal for mounting a primary workpiece on one end and a position flag or cam on the rear rod. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. Note that the adjustable air cushions at both ends only decelerate the piston near stroke limits; they do not hold a load if air pressure drops.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX300 Is Used
Symmetric Force Transfer
Drives a dual-sided mechanism where identical push and pull forces of 3681 N at 0.5 MPa are required for balanced, stable motion.
Anti-Rotation Slides
The twin-rod configuration prevents piston rotation during long 300mm traverses, keeping the tool plate perfectly aligned without external guides.
Through-Rod Sensing
Mounts the primary workpiece on the front rod and a position flag on the rear rod to trigger external sensors, maximizing machine safety.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX300 the Right Cylinder?
Select this 100mm bore when an application requires symmetric actuation or anti-rotation guidance that a single-rod SAI cannot provide. Stepping down to an 80mm bore reduces the both-way force to 2268 N at 0.5 MPa, while the SAID100X300 provides 3681 N each way. The PT tapered ports and standard 300mm stroke make it a drop-in replacement for other ISO 15552 double-rod cylinders.
For a 300mm stroke, the 25mm diameter SUS304 rod carries substantial side loads, but the unsupported length increases rod-bearing bending risk. Always use an external guide rail for heavy off-center loads. Choose the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting accessories to match your frame. Since no magnet is specified, position sensing requires external limit switches mounted to the rear rod or frame.

- ✓ 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 SAID100 Double Rod Cylinder SAID100BX300 FAQ
Because the rod exits both ends, the effective piston area is identical in both directions. It delivers 3681 N of force at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa for both extension and retraction.
Yes, the SAID100X300 is dimensionally interchangeable per ISO 15552 mounting interface dimensions. It uses a standard PT G1/2 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, making it a direct drop-in replacement.
