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.
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 ...
XY tables are flat surfaces mounted on ball bearing slides or roller slides with multiple linear bases and are composed of forcers and platens. [1] The forcer glides over the platen on frictionless air bearings and moves continuously in a linear motion across the platen. To create multiple axis, linear bases are often stacked on top of one ...
A plain bearing, or more commonly sliding contact bearing and slide bearing (in railroading sometimes called a solid bearing, journal bearing, or friction bearing [2]), is the simplest type of bearing, comprising just a bearing surface and no rolling elements. Therefore, the part of the shaft in contact with the bearing slides over the bearing ...
It is a power-driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material. [1] The precise definition of the term machine tool varies among users, as discussed below. While all machine tools are "machines that help people to make things ...
Zaber motorized linear stage. A linear stage or translation stage is a component of a precise motion system used to restrict an object to a single axis of motion. 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.
