The Nil-Union elastic coupling models O and L differ in the length of the crown. The L model has the longest crown, and is especially suitable for use between any receiving machine and an electric motor with alignment problems. Shaft misalignment is considered the second most common source of vibration after unbalance.


Easy to disassemble by means of an extractor.


Applicable to torque limiters, clutches, brakes and everything that requires assembly of two aligned shafts.


These deviations can be presented in three different ways:


Parallel or radial misalignment: This occurs when the center lines of the shafts are parallel apart.

Angular or axial misalignment: this deviation is observed by the angle formed between the center lines in a plane in space.

Combined misalignment: This is the most common of the situations, and it occurs exactly when there are parallel and angular deviations in the same set of center lines.


Characteristics:
Economical.
Easy to install and align.
Resistant and silent.
They do not require maintenance.
Elastic.


The Nil-Union elastic coupling models O and L can be used for different types of machinery, such as:
