Shape of Slideways: With Diagram | Machine Tools

In this way sliding friction is substituted by rolling friction. Fig. 11.19 shows use of ball bearings and Fig. 11.20 shows how rollers can be used between hardened guiding strips to minimize friction. The travel length of non-circulating ball or roller bearing guide ways is limited to about twice the length covered by the balls.

bearing | machine component | Britannica

bearing, in machine construction, a connector (usually a support) that permits the connected meers to rotate or to move in a straight line relative to one another. Often one of the meers is fixed, and the bearing acts as a support for the moving meer. Most bearings support rotating shafts against either transverse (radial) or thrust (axial) loads.
