Assembly and installation of linear guides

Assembly and installation of NSK linear guides (general industrial applications)

There are two methods for installing linear guides. The first method uses a reference surface on the mounting base and enables precise horizontal alignment, similar to machine tools.

The other method uses the first rail as a reference for the second rail and is usually used when smooth movement is more important than high accuracy.

For general industrial applications, NSK recommends the interchangeable NH and NS series linear guides. Their self-aligning feature means greater tolerance for misalignment and less time spent on installation. They are also interchangeable between rail and carriage, making it easy to add or replace parts.

As an authorized distributor, we are at your disposal to help you select the right NSK linear guides and install them for your specific requirements.
