[0002] Linear guides are also called linear rails, slides, and linear slides. Linear guides are used in linear reciprocating motion situations. They can withstand a certain torque and achieve high-precision linear motion under high loads. They are widely used in sliding structures in semiconductor manufacturing equipment, printed circuit board IC assembly equipment, medical equipment, robotic arms, precision measuring instruments, office automation equipment, etc. Linear guides mainly consist of two parts: sliders and guide rails. The slider is the installation support structure of the linear guide and is mainly used for the installation support and guidance of external structures. It is an important working component of the linear guide.

[0003] The slider is supported by rolling between the steel ball structure and the guide rail. The running smoothness of the steel ball determines the running stability of the slider, and the running smoothness of the steel ball depends on the lubrication and sealing of the steel ball. The existing slider has certain defects in the lubrication and sealing of the steel ball. In addition, since the external components have various specifications, there will be certain differences in their installation holes. The holes on the upper part of the existing slider are mostly directly opened on the upper part of the slider. The fixed hole spacing cannot meet the installation requirements of components of different specifications, and the installation versatility is poor. Therefore, a micro linear guide slider mechanism is proposed. Utility Model Content
