Each project should be broken down to the individual applications that will enable the overall project to be realized.
When applying linear motion components to your project, there are many options and considerations. Guide-rails and guide-ways are globally produced in differing forms to suit very specific engineered purposes.
The most common forms of guide-ways and relative bearings are profiled rails with recirculating ball bearing blocks, guide-ways for roller bearings, and round rail with recirculating ball bushings as well as plane bushings.
Initially, each project should be broken down to the individual applications that will enable the overall project to be realized. If the project requires the use of an X-axis, Y‐Axis, and a Z-axis to accomplish the goals of the program, then each of the axis have to be separated for consideration.

Each axis should then be further reduced to its core elements. The direction of motion for each individual axis will have its own and specifically definable set of unique parameters. These parameters will be used to define the linear motion solution that is proper, robust and efficient for the application.
As the linear motion guidance world is generally made up of the above mentioned engineered rail systems, the first level of the selection process begins with the understanding of the overall general customer requirements or program guidelines:
- Repeatability tolerance or accuracy required to achieve the end result.
- Environmental contamination, i.e., dust, water, fibers, etc.
