2. Linear-motion bearing - Wikipedia

   en.wikipedia.org/wiki/Linear-motion_bearing

   A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings.. Motorized linear slides such as machine slides, X-Y tables, roller tables and some dovetail slides are bearings moved by drive mechanisms.

3. Way (machine tool element) - Wikipedia

   en.wikipedia.org/wiki/Way_(machine_tool_element)

   It facilitates precise linear motion along a given axis. A way is ground, scraped, or (less often) molded to be very flat, and ways often come in pairs to ensure a flat plane for the carriage or sliding element (slide) to move along smoothly. Ways are usually lubricated with way oil (a kind of machine oil specially made to adhere to the ways ...

4. Linear stage - Wikipedia

   en.wikipedia.org/wiki/Linear_stage

   The term linear slide is often used interchangeably with "linear stage", though technically "linear slide" refers to a linear motion bearing, which is only a component of a linear stage. All linear stages consist of a platform and a base, joined by some form of guide or linear bearing in such a way that the platform is restricted to linear ...

5. Plain bearing - Wikipedia

   en.wikipedia.org/wiki/Plain_bearing

   Therefore, the part of the shaft in contact with the bearing slides over the bearing surface. The simplest example of a plain bearing is a shaft rotating in a hole. A simple linear bearing can be a pair of flat surfaces designed to allow motion; e.g., a drawer and the slides it rests on [3] or the ways on the bed of a lathe.

6. Bearing (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Bearing_(mechanical)

   A ball bearing. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.

7. Leadscrew - Wikipedia

   en.wikipedia.org/wiki/Leadscrew

   A leadscrew (or lead screw), also known as a power screw [1] or translation screw, [2] is a screw used as a linkage in a machine, to translate turning motion into linear motion. Because of the large area of sliding contact between their male and female members, screw threads have larger frictional energy losses compared to other linkages.
