About the Airtac SAID50 Double Rod Cylinder SAID50AX165S
The AirTAC SAID50X165-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and a 165mm made-to-order stroke. Because a piston rod exits both end covers, the annulus area is identical on extend and retract. This provides an equal push and pull force of 825N at 0.5 MPa, ensuring perfectly symmetric motion dynamics.
Equipped with a -S magnet, this variant directly supports position sensing via AirTAC CMSE (reed) and DMSE (solid-state) switches housed in the dual-side sensor grooves. The rod is constructed from SUS420J2 stainless steel (code A) for heightened corrosion resistance, and the PT tapered port threads guarantee a dependable, leak-free pneumatic connection.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX165S Is Used
Symmetric Force Transfer
Drives a workpiece forward and backward with identical 825N force and speed, ideal for shuttle mechanisms requiring perfectly balanced kinetic profiles.
Dual-Station Actuation
Mounts a primary tool on the front rod end and a secondary cam or position flag on the rear protruding rod to trigger external limit switches.
Anti-Rotation Slides
The twin-rod architecture inherently resists torsional deflection, providing superior load guidance for lifting or pressing fixtures without external guides.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX165S the Right Cylinder?
Select this specific model when an application demands equal bidirectional force and anti-rotation guidance that a single-rod SAI cannot provide. If your mechanism requires less thrust, stepping down to the 40mm bore yields 528N each way at 0.5 MPa; if higher forces are needed, the 63mm bore provides 1402N. Keep in mind that a plain SAID50X165-S will drift and cannot hold a load if air pressure is lost or the valve is centered—always use an external rod lock or a SAIL cylinder for fail-safe holding.
As a dimensionally interchangeable ISO 15552 component, it serves as a drop-in replacement for other standard profile double-rod cylinders. It utilizes a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits the FB, CA, CB, and CR variants found on single-rod counterparts. Because the stroke is 165mm, the extended rear rod requires adequate clearance, and for any stroke reaching 300mm or more, an external guide is recommended to prevent rod-bearing bending under side loads.

- ✓ 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 SAID50 Double Rod Cylinder SAID50AX165S FAQ
Because the rod occupies both sides of the piston, the effective area is the same in both directions. It delivers an equal push and pull force of 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa.
Yes. The SAID50X165-S is built to ISO 15552 mounting interface dimensions, making it a drop-in replacement for other standard profile double-rod cylinders. It uses a G1/4 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
