SWC-WF Without Flex Flange Type Universal Coupling

Raydafon’s SWC-WF Without Flex Flange Type Universal Coupling is made just for high-torque transmission in heavy machinery—think metallurgy equipment, cranes, mining systems, all the tough setups that need steady power. It has a non-flexible flange design, gyration diameters ranging from 160mm to 640mm, and this flange type universal coupling handles big angular misalignments plus continuous rotary speeds no problem, even when working in super demanding conditions. We use high-strength 35CrMo steel to build it, so it stands up to intense loads perfectly—exactly why it’s a top pick for universal couplings for heavy machinery and non-flex universal couplings for industrial applications. Raydafon’s precision manufacturing makes sure it delivers solid performance every time, especially for industries that can’t compromise on consistent torque delivery.

This SWC-WF universal coupling is built to last, with a rigid flange connection that makes installation easy in systems like shipbuilding drives and rolling mills—places where axial movement isn’t much. We follow ISO 9001 standards strictly, and our China-based factory uses advanced machining plus tight quality checks to make this durable flange universal coupling. It comes in customizable sizes, with torque ratings up to 1250 kN·m, so it fits right into custom universal couplings for metallurgy equipment and other heavy-duty setups. Raydafon also offers tailored solutions at competitive prices, helping cut down on downtime and boost your equipment’s reliability.

Work Principle

Raydafon’s SWC-WF without flex flange type universal joint coupling—also called the SWC cardan shaft universal joint coupling—works on a basic mechanical idea: it gets torque from two non-collinear shafts to where it needs to go, and it handles misalignment too. This high-torque universal joint coupling uses a cross-bearing setup to link the flanges on both ends, so even when the shafts are offset by up to 25 degrees or have axial/radial deviations, it still moves rotational power smoothly.

The heart of how it works is the universal joint design—there’s a cross shaft that acts like a pivot, letting each flange move on its own. That way, torque goes from the driving shaft to the driven shaft efficiently, and it makes up for angular misalignments without putting too much stress on the parts it’s connected to. If you need a reliable heavy-duty universal joint coupling for rolling mill operations, this one’s rigid, non-flexible flange structure keeps things stable, which is perfect for short-distance connections in compact heavy machinery setups.

What makes its function stand out is that it doesn’t have flexible parts or expansion features—this sets it apart from other types and makes it great for places where axial movement is minimal. The durable SWC universal joint shaft coupling we use in lifting and material handling equipment leans on this principle to stay balanced even under big loads; it hits transmission efficiencies up to 98.6% and doesn’t waste much energy. This industrial universal joint coupling also cuts down on vibrations thanks to precise bearing movement, so it runs smoothly even in high-stress situations—just like the heavy machinery universal joint coupling systems you’d see in tough industrial jobs.

Plus, Raydafon’s SWC heavy-duty universal joint coupling has welded flanges to make it sturdier—no more worrying about bolts coming loose, and it boosts overall strength by 30% to 50%. As an efficient universal joint coupling for large power transmission, it handles nominal torques from 0.15 to 1000 kN·m and has gyration diameters from φ58 to φ620—making it a top pick for energy-saving universal joint coupling solutions in demanding industrial transmissions. And with noise kept between 30-40 dB(A), this low-noise universal joint coupling runs quiet, which is ideal for industrial spots where noise is a concern, all while keeping up high reliability standards.

Scope of Application

Raydafon’s SWC universal joint coupling—often called the SWC cardan shaft universal joint coupling—isn’t just a regular part; it’s a must-have for heavy-duty industrial setups, like rolling mills, hoisting machinery, and all kinds of tough heavy machinery systems. As a high-torque universal joint coupling, it does a solid job linking two transmission shafts that don’t line up perfectly, making sure power keeps flowing even when the working conditions get rough.

Let’s talk about its key specs: the gyration diameter ranges from φ58 to φ620, nominal torque goes from 0.15 to 1000 kN·m, and the axis fold angle is no more than 25°.

This product really shines in specific scenarios—like when you need a reliable heavy-duty universal joint coupling for rolling mill operations, or a durable SWC universal joint shaft coupling in lifting and material handling equipment. In these cases, it proves its worth by keeping operations stable, even when it’s dealing with heavy loads.

Structural Features

Raydafon’s SWC universal joint coupling isn’t just built for function—it’s engineered with smart design to hold up in industrial use and keep performing well long-term. Let’s break down what makes its structure stand out.

First, it has a reasonable and safe configuration: we used an integrated fork head design for this industrial universal joint coupling, which cuts down on risks like bolts coming loose or breaking. That alone boosts its structural integrity by 30%-50%, so it works safely and reliably. Compared to regular couplings, it lasts longer and avoids common breakdowns in high-stress spots—like the heavy machinery universal joint coupling systems you see in tough jobs.

Then there’s its enhanced load-bearing capacity: this SWC heavy-duty universal joint coupling is made to handle big weights, so it’s a must-have in places that need top-notch load management, like mining or construction machinery.

It also delivers high transmission efficiency—hitting up to 98.6%. As an efficient universal joint coupling for large power transmission, it cuts down energy use and the costs that come with it. That’s why it’s a top choice for energy-saving universal joint coupling solutions in high-power industrial transmission setups.

And it runs smooth with low noise: it keeps transmission steady, and noise usually stays between 30-40 dB(A). This low-noise universal joint coupling makes sure operations stay quiet, which is perfect for places where noise is a problem—all while keeping reliability at a high level.
