SWC-WH Without Flex Welding Type Universal Coupling

If you’re running heavy machinery—like steel rolling mills that churn out metal all shift, cranes lifting tons of material, or mining gear that battles dust and pressure underground—you need a coupling that won’t let you down. That’s exactly what Raydafon’s SWC-BH Standard Flex Welding Type Universal Coupling is built for: reliable torque transmission, even when the job gets rough.

First off, let’s talk about its design. The welded yoke isn’t just a feature—it’s a game-changer. Unlike bolted yokes that can loosen up over time, this one’s welded solid, so there’s no risk of parts shaking loose when your machinery’s working hard. And it fits a range of setups too, with gyration diameters from 180mm to 620mm—no need to hunt for a one-size-fits-none option. As a standard flex universal coupling, it handles up to 15 degrees of angular misalignment, which means if your shafts aren’t perfectly lined up (and let’s be real, they rarely are), it still keeps power moving. Even when torque hits 1250 kN·m—serious power—it stays steady, no stutters, no drops.

We didn’t skimp on materials, either. This thing’s made with 35CrMo steel—high-strength stuff that resists wear, even when it’s getting banged around in a mine or heated up near a rolling mill. Plus, we put in precision needle bearings, so it moves smooth, cuts down on friction, and lasts way longer than cheaper couplings. That’s why it’s a go-to for universal couplings for heavy machinery—it doesn’t just work for a few weeks; it sticks around, keeping your equipment running. And if you need welded universal couplings for industrial applications? This is it— the welded design handles vibration and stress better than bolted alternatives, so you spend less time fixing and more time working.

At Raydafon, we make these in China, but we don’t cut corners on quality. Every step follows ISO 9001 standards—we check the steel, we inspect the welds, we test the bearings—so you know you’re getting a coupling that meets global quality rules. And if your setup is a little different? We do custom tweaks—adjust the size, tweak the specs—whatever you need to make it fit. Best part? It’s not priced like a luxury part. You get a durable universal coupling that works hard, without paying a fortune. For anyone who can’t afford downtime, this SWC-BH coupling is the kind of reliable piece that keeps your machinery moving, day in and day out.

Product Specification

Product Advantages

If you’re tired of dealing with fussy couplings that slow down your work or break when you need them most, Raydafon’s SWC-WH Without Flex Welding Type Universal Coupling is a game-changer. It’s packed with perks that make it a top pick for anyone needing smooth torque transmission in mechanical systems—no confusing welding steps, just solid performance that fits right into your workflow.

First off, installing this thing is way easier than you might think. Unlike welded couplings that force you to bring in extra tools or wait for welds to set, the SWC-WH uses a bolt-on design. You can slot it into your existing setup fast, and when it’s time for maintenance? Taking it apart is a breeze, so your industrial gear spends less time idle. That’s why it’s such a great versatile high-torque universal joint coupling—no downtime headaches, just get in, fix what you need, and get back to work.

Durability-wise, it’s built to tough it out. We use heavy-duty materials that handle big loads and constant vibrations without flinching—perfect for busy industrial spots where equipment never really gets a break. And since there’s no welding, you don’t have to worry about those weak spots that pop up when welds wear out over time. This isn’t a coupling that’ll need replacing every few months; it’s a reliable universal joint coupling for industrial machinery that sticks around, keeping your operations steady.

Misalignments? No problem. Shafts never stay perfectly lined up, especially in automotive or transportation systems, but the SWC-WH handles angular, axial, and radial deviations like a pro. It’s the kind of drive shaft universal joint coupling that keeps power moving smoothly even when alignment gets wonky—no jerks, no drops, just consistent performance.

And let’s talk cost. Welding adds extra labor and material fees, but this coupling skips all that. You get a quality product without overspending, which is a big win for any budget. Even in tricky spots like marine setups, where corrosion is a constant threat, it holds up as a reliable marine universal joint coupling—tough against saltwater, easy on your wallet.

If you’re into renewable energy, this coupling fits right in too. It’s a solid universal joint coupling for renewable energy equipment that moves power efficiently, with barely any waste. Plus, it’s light, so it doesn’t weigh down your system—great for keeping things running sustainably without sacrificing performance.

At Raydafon, we don’t just sell couplings—we make ones that fit your needs. The SWC-WH is customizable, so it works exactly how you want it to. If you’re curious how it can make your operations smoother, just hit up our team. We’ll walk you through it, no jargon—just straight talk about what this coupling can do for you.

Work Principle

Raydafon’s SWC-WH Without Flex Welding Type Universal Coupling works off the basic know-how of cardan joint mechanics—but we’ve tweaked it to hit harder for industrial jobs. The whole point? Get torque moving smoothly between two shafts that aren’t perfectly lined up, even when they’re at an angle. As a purpose-built SWC cardan shaft universal joint coupling, it uses a cross-shaped piece in the middle to keep rotational power flowing steady—exactly why it’s such a go-to high-torque universal joint coupling for tough work like rolling mills or hoisting machinery.

Let’s break down the core of how it works: there are two forked yokes, and they’re connected by a central cross (we call it a spider). This setup lets the yokes pivot in multiple directions—so even if the shafts are offset by up to 25° (that’s its max axis fold angle), torque still gets passed along evenly. It’s got specs to back that up, too: gyration diameters range from φ58 to φ620, and it handles nominal torque from 0.15 to 1000 kN·m. When you’re using it as a heavy-duty universal joint coupling for rolling mill operations, this design means input rotation turns into output motion without a hitch—those articulated joints pivot on their own to make up for misalignments, no interruptions.

What makes the “without flex welding” part matter? We swapped out welds for bolted or clamped connections. Welds can be weak spots over time, but these fasteners cut down on failure risks—and they make putting the coupling together way easier, too. This industrial universal joint coupling also has an upgraded fork head design that stops bolts from loosening up, boosting its structural strength by 30%-50%. That’s a big deal for demanding spots like mines or construction sites, where it acts as a durable SWC universal joint shaft coupling—holding up under heavy loads without giving out.

Efficiency is another win here: it hits up to 98.6% transmission efficiency. We engineered every part to cut down on friction and energy waste—so it’s no surprise it’s an efficient universal joint coupling for large power transmission in high-power industrial setups. And it runs quiet: usually 30-40 dB(A). That’s thanks to balanced rotation and built-in vibration damping—making it a low-noise universal joint coupling for places where noise is a problem. Plus, it keeps energy costs down, so it checks the box for energy-saving universal joint coupling needs too.

In heavy machinery universal joint coupling systems, this matters most: the SWC-WH spreads out forces evenly across all its parts. No single piece takes too much strain, which means fewer breakdowns and a longer life. At Raydafon, we don’t just build this coupling to meet specs—we tailor it to work for your job, whether that’s rugged heavy machinery or specialized industrial setups. If you want to tweak it to make your system run smoother or last longer, just talk to our team—we’ll help you get a setup that fits exactly what you need.
