In some applications, what is necessary to install a chain?

In various applications involving chain installations, utilizing a master link is essential. A master link serves as a connecting point for the ends of the chain, allowing for easy installation and removal without the need to dismantle other components of the assembly. This component is designed specifically for this purpose, making it easier to replace or adjust the chain when necessary, thereby enabling maintenance practices to be carried out more efficiently.

While alignment of both shafts is crucial in ensuring proper operation and preventing undue wear, and moving shafts can occasionally be necessary in specific applications, these aspects do not directly facilitate the initial installation of a chain. The master link's role is fundamental because it provides the means to connect the links of the chain seamlessly, which is a key requirement for proper chain functioning in any setup.
