A linear guideway can be powered by a motor or the mechanism can be moved along the rail by hand. Various types of bearings or rolling parts can be used inside the linear motion guide to allow it to roll smoothly along the guide rail.
Some linear guideways use ball bearings to slide along the rail, but others use roller bearings or magnetic bearings.
Ball bearing slides are the most common. Ball bearing linear guideways are smooth and precise because they operate on a single axis using self-lubricating ball bearings in a linear base.
A roller bearing, also known as a rolling element bearing, has an outer ring with several balls within that are contained by cage-like structures. These are economical and long lasting bearings that cause minimal friction.
Magnetic bearings use two encased magnets whose polarized forces oppose each other. This repelling force creates smooth and controlled motion along the rail. A linear table is a small table that is attached to a linear guideway.
Items can be placed on this table and moved along the rail, and sometimes a table is attached to two rails on a linear guideway to provide a higher weight capacity.
Linear guideways are used in all kinds of household and industrial applications. Even common household features like sliding doors or drawers use a type of linear guideway to allow for opening and closing movement.
Conveyor belts in some automated factory assembly lines use linear guideways to keep products moving down the assembly line and on to the next stage of the manufacturing or packaging process.
In industrial or household settings, linear motion systems help to make tasks easier and more efficient every single day.
