About the Airtac SAID100 Double Rod Cylinder SAID100X425
The AirTAC SAID100X425 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 425mm stroke. Because a carbon steel rod exits both ends, the effective piston area is identical on extend and retract, yielding an equal force of 3681 N each way at 0.5 MPa. This twin-rod architecture is purpose-built for applications requiring dual-side guidance, anti-rotation stability, or mounting a secondary mechanism and position flag on the rear rod.
The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Adjustable air cushions at both ends decelerate the piston over a 36mm stroke length, though note that a plain SAID relies on live air pressure and will drift if supply is lost, as the cushion is not a locking brake. It supports a reduced set of ISO 15552 mounting accessories (Basic, FA, LB, TC, FTC, TCM1, TCM2) and uses a PT G1/2 port.

Where the Airtac SAID100 Double Rod Cylinder SAID100X425 Is Used
Symmetric Transfer Unit
Drives a dual-sided transfer mechanism where equal push and pull forces of 3681 N are required to shuttle parts seamlessly between two stations without speed variation.
Anti-Rotation Machining Slide
Uses the twin-rod geometry to guide a machining head, preventing torsional deflection during clamping while allowing a rear flag to trigger a DMSE electronic sensor.
Dual-Station Actuator
Simultaneously operates a primary workpiece on the front rod and a secondary cam mechanism on the rear rod, optimizing cycle timing in automated assembly lines.
Is the Airtac SAID100 Double Rod Cylinder SAID100X425 the Right Cylinder?
Select this 100mm bore when an application demands symmetric force and speed both directions, stepping up from the 80mm bore (which provides 2268 N both ways at 0.5 MPa) or dropping down from the 125mm bore (5734 N both ways). A double-rod cylinder is chosen over a single-rod SAI when the mechanism requires a rear-rod cam, a secondary tool station, or strict resistance to torsional rotation. For this 425mm stroke, the long unsupported rod length increases the risk of side-load bending at the rod bearing, so an external guide rail should be used to support heavy off-center loads.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. To configure: verify the 425mm stroke fits your standard stroke range (max 1500mm for this bore), specify PT threaded ports, select a mounting accessory from the SAID-compatible set, and note that no -S magnet is specified for this configuration.

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.
