About the Airtac SAID100 Double Rod Cylinder SAID100BX900
The AirTAC SAID100X900 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 900mm stroke. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding an equal extend and retract force of 3681 N at 0.5 MPa. This symmetric output is ideal for mechanisms requiring consistent push and pull dynamics.
This variant is equipped with a SUS304 stainless steel rod, offering superior corrosion resistance for harsh environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the through-rod design extends past the rear cover, requiring additional clearance and providing a convenient mounting point for a cam or position flag.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX900 Is Used
Symmetric Transfer
Drives a workpiece back and forth with identical force and speed in both directions, ensuring stable cycle times.
Anti-Rotation Slide
The twin-rod design resists torsional twist, keeping guided loads perfectly aligned without external rails.
Rear-Cam Actuation
Uses the protruding rear rod end to trigger a mechanical limit valve or cam, independent of the main tool.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX900 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (2268 N at 0.5 MPa) lacks sufficient thrust, but a 125mm bore is oversized. The twin-rod architecture is selected over a single-rod SAI when the application demands dual-side guidance to prevent rotation, or when a secondary mechanism must be driven from the rear rod. Standard PT G1/2 ports and adjustable air cushions at both ends manage the 30-800 mm/s speed range.
Because this model features a 900mm stroke, the long unsupported rod is susceptible to bending under side loads. An external guide rail should be installed to prevent rod-bearing wear. Remember that a plain SAID does not hold its load if air pressure drops; use a SAIL or BSAID clamp-lock cylinder if fail-safe positioning is required. It is dimensionally interchangeable per ISO 15552.

- ✓ 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.
