Different working environments require different loads and models of products.The kinds of linear guide rail could be cut for different lengths and models to splice and install, it’s high reliability and practicability.
CHTR linear guide guideway is designed with four columns arc grooves which increase the contract area, it has been greatly improve on the loading capacity , contact stiffness and system rigidity.
Linear guides are mainly used in mechanical structures with high precision requirements, such as grinding machines, lathes, woodworking machines, handling machines, transport devices, industrial automation machines, semiconductor machinery, packaging machines, etc.

The modern, self-aligning design of ball bearing is attributed to Sven Wingquist of the SKF ball-bearing manufacturer in 1907, when he was awarded Swedish patent No. 25406 on its design.
Henry Timken, a 19th-century visionary and innovator in carriage manufacturing, patented the tapered roller bearing in 1898. The following year he formed a company to produce his innovation. Over a century the company grew to make bearings of all types, including specialty steel and an array of related products and services.
Erich Franke invented and patented the wire race bearing in 1934. His focus was on a bearing design with a cross section as small as possible and which could be integrated into the enclosing design. After World War II he founded together with Gerhard Heydrich the company Franke & Heydrich KG (today Franke GmbH) to push the development and production of wire race bearings.
Richard Stribeck’s extensive research [10][11] on ball bearing steels identified the metallurgy of the commonly used 100Cr6 (AISI 52100) [12] showing coefficient of friction as a function of pressure.
