About the Airtac SAID100 Double Rod Cylinder SAID100BX185
The AirTAC SAID100X185 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 185mm stroke. Because a stainless steel SUS304 rod exits both end covers, the effective piston area is identical on extend and retract. This provides an equal 3681N of force in both directions at 0.5MPa, ensuring symmetric thrust and speed for demanding transfer tasks.
The twin-rod architecture allows you to mount the primary workpiece on one end and a position flag or cam on the rear rod for dual-side guidance. The extruded aluminum barrel includes sensor grooves on both sides. Note that because the rear rod protrudes, you must allow extra clearance at the back of the cylinder for the full stroke travel.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX185 Is Used
Symmetric Transfer
Drives a workpiece back and forth with equal 3681N thrust on both strokes, ensuring perfectly balanced motion for automated assembly shuttles.
Anti-Rotation Slides
The twin-rod design inherently resists torsional loads, keeping heavy guided carriages from twisting during vertical or horizontal actuation.
Dual-Side Tooling
Mount the primary tool on the front rod end and a secondary cam or position flag on the rear rod to actuate external limit switches without extra brackets.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX185 the Right Cylinder?
Select this 100mm bore when an application requires true bidirectional power and higher anti-rotation resistance than a single-rod SAI. It delivers 3681N each way at 0.5MPa; if you need less force, step down to the 80mm bore (2268N both ways), or move up to 125mm (5734N) for heavier loads. The PT G1/2 port handles the required air volume efficiently.
This cylinder uses a SUS304 stainless steel rod for superior corrosion resistance. It supports the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) but omits the FB, CA, CB, and CR accessories found on single-rod variants. It is dimensionally interchangeable per ISO 15552. Keep in mind the adjustable air cushions only decelerate the piston near stroke end; if the air supply is lost, the cylinder will drift and cannot hold a load without an external pilot-operated check valve or a BSAID clamp-lock.
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 SAID100 Double Rod Cylinder SAID100BX185 FAQ
Because the double-rod design has the same annulus area on both sides, the push and pull forces are equal. It delivers 3681N both ways at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa.
Yes. The SAID100X185 is an extruded aluminum profile cylinder with a standard ISO 15552 mounting interface, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a PT G1/2 port and a 25mm rod.
