Bearings enable components to move together smoothly while offering both support and alignment. Linear bearings, in particular, support the load of a carriage while providing a low friction surface for guide rails to slide against. Guide rails are fitted and inserted into the linear bearing while the carriage travels back and forth along its length. Linear bearings feature either a rolling element or fluid device to reduce friction, and they ensure superior mounting, additional precision, and smoother motion. Because of their positive capabilities, they are often found in 3D printers, sliding doors, and many automated applications in which guiding rail motion is necessary. 

When machinery, devices, and other such assemblies feature moving parts, it is important that there are means to control said movements and a solution in place to deter the effects of friction and rubbing that may result from operations. Whether motion comes in the form of linear sliding or rotary movements, components such as aviation bearings and bushings may be used to accommodate high speeds while mitigating stress. While bushings are technically a form of bearing, they slightly differ in their features and capabilities. As such, we will provide a brief overview of each component so that you can have a better understanding of what may work best for a particular need.
