Couplings / U-Joints

Couplings and U-joints are used to connect rotating shafts or other moving components and transmit motion to other parts of the assembly.

There are categories of shaft couplings—flexible shaft, rigid, and universal joints (U-joints). MW Industries produces both flexible shaft and J-joints. Flexible shaft couplings and U-joints are used when there is a degree of misalignment between connections. Standard flexible shaft couplings including beam couplings and servo couplings are used to accommodate small misalignments and U-joints are used in situations where misalignment angles are greater than a standard flexible coupling can manage.

MW Components produces multiple styles of flexible shaft couplings for various industries and applications. We even make custom couplings to your exact specifications. View our options for available parts or request a custom quote today.

Custom Couplings & U-Joints

MW’s customization capabilities are vast, including various options for materials, secondary processes and finishes, and optional certifications. We produce several standard and custom coupling configurations with your needs in mind. No matter your performance requirements, we can create a coupling that is fit for the job. Some examples of applications where custom couplings may be required include; elimination of end-play, zero backlash, close tolerance requirements, spring elimination, and minimum windup or torsional stiffness. We have decades of experience working with customizations of all types and offer added design, tooling, and prototyping assistance as needed. Contact us for custom quote information to learn more.
