A slider is formed by a metallic main body, a synthetic resin-made frame, and a pair of end caps. The frame is detachably fitted to outer sides of the main body. Ball rolling grooves are provided in the main body. Return paths and inside grooves of a direction changing path are provided in the frame. An outside groove of the direction changing path are provided in each end cap. A paste-like filler is applied to a boundary portion between the main body and the frame and a boundary portion between the frame and the end cap, and is allowed to cure.

Linear guide apparatus and method for assembling the same

Disclosed is a linear guide device in which a rate of change expressed as 'Dmax&#x2212;Dmin', becomes extremely small where Dmax and Dmin are respectively a local maximum and a local minimum of D, expressed as (dxdx)/dx, which is produced when a steel ball B moves a distance corresponding to a rolling element-to-rolling element span, dxis a minute movement quantity of a steel ball B when it moves from one space defined between rolling element rolling groovesandof an element endless circulating racewayto one of curved element circulating R partsand dxis a minute movement quantity of another steel ball B when it moves from the other curved element circulating R partto the space while the former steel ball is moved by the minute movement quantity dx

Linear guide device

A linear guide device in which a rate of change expressed as &ldquo;Dmax&minus;Dmin&rdquo;, becomes extremely small where Dmax and Dmin are respectively a local maximum and a local minimum of D, expressed as (dx2&minus;dx1)/dx, which is produced when a steel ball B moves a distance corresponding to a rolling element-to-rolling element span, dx1 is a minute movement quantity of a steel ball B when it moves from one space defined between rolling element rolling grooves and of an element endless circulating raceway to one of curved element circulating R parts and dx2 is a minute movement quantity of another steel ball B when it moves from the other curved element circulating R part to the space while the former steel ball is moved by the minute movement quantity dx1.
