System and Component Selection Information
PIC offers ten standard linear motion systems. Each system is available in either
inch or metric sizes and a wide range of dimensions. Choosing the system that best suits
the application is normally a function of the design engineering department. The
information provided in this section will enable users to select all standard PIC
components required for the chosen system and application.
To select the appropriate components for a system, all
loads and the magnitude and direction of forces for the application must first be
determined. This information will aid in the selection of the appropriate linear bearings
to carry the load and provide the desired system life. After determining the bearing load
and evaluating shaft deflection, the designer can select the necessary components from the
PIC standard parts listed for each system.
Many factors are involved in the selection
of a linear motion system and its components. The steps usually required
for such selection are as follows:
1. Selection of the type of system that best suits the
application
2. Calculation of system loading and bearing selection
3. Determination of shaft deflection
4. Selection of other system components
5. Selection of lead screw assemblies (systems 7 through 10).

PIC now offers a comprehensive line of linear motion systems,
either pre-assembled or as complete component sets for user assembly. Specifying these PIC
products is a smart, cost-effective approach for a wide spectrum of applications. Single
sourcing eliminates the need for extensive, expensive component and system design and
time-consuming searches through different manufacturers' catalogs for all required designs
and sizes. Because all PIC linear motion systems feature modular design,
assembly is simplified and all parts fit together precisely.
