About the Airtac SAID50 Double Rod Cylinder SAID50AX450
The AirTAC SAID50X450 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 450mm stroke. Because a piston rod exits both end covers, the effective annulus area is identical on extension and retraction, yielding a perfectly symmetric 825N of thrust and pull force at 0.5 MPa. This through-rod architecture is highly valued for applications requiring dual-side guidance, anti-rotation stability, or the ability to drive a secondary mechanism from the rear rod end.
Built for demanding environments, this specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance. 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 near stroke end to minimize impact, though they do not function as a locking mechanism.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX450 Is Used
Symmetric Force Transfer
Ideal for pushing and pulling loads that require identical 825N force and speed in both directions, ensuring smooth, balanced motion without differential acceleration.
Rear-Rod Cam Actuation
The protruding rear rod end drives a secondary mechanism or cam, allowing designers to trigger external limit switches or synchronize a secondary tool alongside the primary workpiece.
Anti-Rotation Slides
Twin rods exiting both covers provide superior guidance and resist torsional deflection, making this cylinder perfect for non-rotating lifters and precision handling slides.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX450 the Right Cylinder?
Selecting this 50mm bore over a smaller 40mm variant increases your both-direction force from 528N to 825N at 0.5 MPa, while stepping up to a 63mm bore provides 1402N if your payload demands greater thrust. A double-rod design is chosen over a single-rod SAI when the mechanism requires strict anti-rotation control or needs to mount a position flag and cam on the rear rod end. Be aware that a plain SAID does not hold its position if air pressure is lost; if load holding is required, consider an SAIL lock, a BSAID clamp-lock, or an external pilot-operated check valve.
This model uses PT tapered port threads (G1/4) and is dimensionally interchangeable per ISO 15552 standards, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. At a 450mm stroke, the unsupported rod length is significant; to prevent rod-bearing bending under heavy side loads, use an external guide rail. The available mounting accessory set is reduced to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on single-rod versions.

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 SAID50AX450 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions. It provides 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa.
Yes, the SAID50X450 is dimensionally interchangeable per ISO 15552 standards and serves as a drop-in replacement for other ISO 15552 double-rod profile cylinders. It uses PT tapered G1/4 ports.
