Nil-Union elastic coupling Model S and LS


Nil-Union elastic coupling model S and LS, offers specific solutions to common challenges in industrial environments.

From misalignment correction to adaptability in various applications, these couplings are positioned as an essential tool for optimising the performance of machinery and electric motors.

With their ability to address misalignment, they contribute to the efficiency and longevity of industrial systems.


What is the Nil-Union elastic coupling Model S and LS?


The Nil-Union elastic coupling Model S and LS are devices designed to address common challenges in industrial environments, specifically those related to misalignment between receiving machinery and electric motors.

Misalignment between shafts is a frequent cause of vibration in industrial systems, being the second most common source after unbalance.

Optimising performance with Nil-Union Elastic Couplings

In the industrial world, precise alignment between receiving machinery and electric motors is essential to avoid problems such as vibration and unbalance.

Nil-Union elastic couplings stand out, offering specific solutions to address alignment challenges. Among these, the S and LS models stand out as protagonists, differentiated by their crown length.

Alignment challenges: Beyond imbalance

When we dive into the universe of industrial machinery, misalignment between shafts emerges as the second most common source of vibrations, after unbalance. This is where Nil-Union Elastic Couplings shine by providing specific solutions to this problem.

Model S vs. Model LS: the difference in crown length

One of the distinguishing features between the Nil-Union flexible coupling type S and LS of the Nil-Union flexible couplings is the length of the crown.

The LS model stands out as it has a longer crown compared to its counterpart, el modelo S. This difference allows for the mounting of the coupling pinion on top of the shaft, providing flexibility in various machine configurations.

Versatility in applications: beyond engine alignment

These couplings are not only limited to solving alignment problems between electric motors and host machinery. Their versatility extends to applications that require the assembly of two aligned shafts, such as torque limiters, clutches and brakes.

Their intelligent design and ability to adapt to various configurations make them an ideal choice for demanding industrial environments.

Types of Misalignment: Understanding the Variants

To effectively address misalignment challenges, it is crucial to understand the different ways in which misalignment can manifest itself.

Parallel or radial misalignment, angular or axial misalignment, and combined misalignment are the three possible presentations.

The Nil-Union Elastic Coupling stands as a comprehensive solution, effectively addressing these variations.
