The guide rail and block system consists of a combination of rails and sliders. Guide rails are also known as linear guides, slide rails, linear guides and linear slides. Blocks alos called slide carriages, linear guide blocks, linear block bearings. The slider transforms the motion from a curve to a straight line. The linear guide slider system is known in the mainland. Taiwan is often referred to as linear guides and linear slides.
It is used to support and guide moving parts and perform reciprocating linear motion in a given direction. According to the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides and fluid friction guides.
The function of the linear guide motion is to support and guide the moving parts to make a reciprocating linear motion in a given direction. Linear bearings are mainly used in automation machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc. Linear guides are mainly used on mechanical structures with high precision requirements, moving parts and fixed components of linear guides. Instead of an intermediate medium, a rolling steel ball is used.
Taiwan Guide raila and blocks/carriages system BGC Cage type In traditional linear guide design, the steel balls rotate between the guide and carriage. The relative speed on the steel ball contact point is twice that of the rotational speed. In addition, the contact surface A of traditional guides between steel balls is very small. As the contact pressure (P) moved toward infinity (P = the mutual pressure exerted among the steel balls (F)/contact surface (A). Therefore, the steel balls are easily worn out in traditional guides. The BGC series contain lubricant between steel balls and the friction produced is absorbed by the oil film. Thus, this series is suitable for high speed use.
BGC complete cage design
The linear guide is designed with a separator between the steel balls. Because the external shape of the separate and the manufacturing principles are different, it is hard to completely distribute them throughout the entire loop. The end portion may leave a gap that is 1 or 1/2 size of a steel ball. The BGC linear guide design overcomes this problem, and can evenly distribute them throughout the loop, so that the forces received are more even, providing a more stable overall lifetime.
