CNC Linear Shaft Bearings (Pack of 2)

Linear bearings are rolling-element and fluid-film devices that reduce friction in motion systems where the motion acts along a straight — or sometimes curved — pathway. They are distinguished from radial bearings in which motion is rotary.

Linear bearings are used in machine tool applications such as sliding doors, 3D printers, CNC Machines and automation settings where reducing friction and guiding linear motion is needed. They can be loosely grouped as ball and roller types that use the rolling motion of rolling elements and sliding types that rely on lubricant and low-friction surfaces.
