Linear Motion Guide

Product Description

Linear guides are mainly used in mechanical structures with relatively high precision requirements. There is no intermediate medium between the moving and fixed components of the linear guide, however rolling metal balls. Because the rolling metal ball is suitable for high-speed motion, has a small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as the device holder and carriage of the machine tool. If the force acting on the metal ball is too large, the steel ball will withstand the preload for too long, which will increase the motion resistance of the bracket.

Description

The DF (45-°45)° combination from the arc groove, when installed, due to the elastic deformation of the metal ball and the transfer of the contact point, even if the set up surface has some deviation, it can be absorbed by means of the inside of the linear guide slider, producing the effect of automatic self-alignment and acquiring high-precision, stable and smooth motion.
Interchangeability
Due to the strict control of manufacturing precision, the dimension of the linear guide can be maintained within a certain level, and the slider has a retainer layout to forestall the steel ball from falling off, so some series of precision are interchangeable. Customers can order guides or sliders as needed, and can also store guides and sliders separately to reduce storage space.
High rigidity in all directions
The use of four-row arc grooves, combined with 4 rows of metal balls and a 45-degree contact angle, allows the steel balls to acquire an best two-point contact structure, which can withstand loads from the upper and lower and left and proper directions; when necessary, pre-pressure can be utilized to enlarge rigidity.
