Linear bearings are a type of bearing that "bear" or support the load of the carriage during its single-axis linear movement and provide a low friction sliding surface for the guide rails. In a linear guide, the carriage is the component that travels in a straight line, back and forth, along the length of the guide rail.

Essentially, these two competing vibrating screen types have developed differing material sieving motions. For linear vibrating screens, straight line screening dominates, with the equipment deck moving rocky material forwards and backwards. There's also an amplitude component in the mix, which kicks the loosely packed aggregate up and forward. Circular motion screens simply replace that straight
