About the Airtac SAID100 Double Rod Cylinder SAID100BX85S
The AirTAC SAID100X85-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and an 85mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on both sides. This means the extend and retract forces are perfectly equal, providing 3681N of thrust and pull at 0.5 MPa. The twin-rod architecture is specifically designed to mount a primary workpiece on one end and a secondary guide, cam, or position flag on the opposing rear rod.
This specific configuration includes a piston magnet (-S) for electronic position sensing and utilizes SUS304 stainless steel rods (material code B) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, seamlessly accommodating AirTAC CMSE reed and DMSE solid-state switches. Adjustable air cushions at both ends decelerate the piston near stroke limits to minimize impact wear.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX85S Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull forces (3681N at 0.5 MPa), ensuring consistent speed and power regardless of travel direction.
Anti-Rotation Slides
Twin SUS304 rods prevent piston rotation during vertical or horizontal slides, allowing precise multi-axis machining or clamping without torsional deflection.
Dual-Station Actuation
Mounts a primary tool on the front rod and a secondary cam or position flag on the rear rod to trigger AirTAC DMSE sensors for two-station sequencing.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX85S the Right Cylinder?
Selecting this 100mm bore over a smaller 80mm option jumps the bidirectional force from 2268N to 3681N at 0.5 MPa, while stepping up to a 125mm bore yields 5734N. The double-rod design is chosen over a single-rod SAI when an application demands anti-rotation stability, dual-side load guidance, or rear-rod position sensing. Since the 85mm stroke is under 300mm, side-load bending stress on the rod bearing is minimal, though external guides remain beneficial for heavy radial loads.
This cylinder is dimensionally interchangeable per ISO 15552, acting as a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a PT tapered G1/2 port, a standard 85mm stroke, and the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. Note that a plain SAID does not hold its position if air pressure is lost; for dead-end holding, consider an SAIL lock, BSAID clamp-lock, or external pilot-operated check valve.

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 SAID100BX85S FAQ
Because the rod occupies both sides of the piston, the extend and retract forces are equal. The SAID100X85-S generates 3681N at 0.5 MPa, 5153N at 0.7 MPa, and 6626N at 0.9 MPa in both directions.
Yes, the SAID100X85-S is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 profile double-rod cylinders. It uses the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and a G1/2 port.
