[0003] The existing patent CN213632010U discloses a slider adjustment assembly on a linear guide rail, which uses an Allen wrench tool to tighten the ball plunger, and utilizes the friction between the elastic tube and the ball in the ball plunger to increase the friction between the ball on the head of the ball plunger and the damping strip without losing the accuracy and friction of the linear guide rail itself, thereby ensuring that the slider does not move when the actuator block is slightly vibrated or an external force is applied; at the same time, when the ball plunger is adjusted to reach the required friction, the set screw is tightened to ensure that the deformation of the spring in the ball plunger remains unchanged, thereby ensuring the constant friction between the ball on the head of the ball plunger and the damping strip.

[0004] The existing device is generally a ball linear guide. The slider and the guide rail slide through contact. The size of the ball determines the size of the gap between the guide rail and the slider. The reason why the guide rail slider has a difference in tightness is because of the size of the gap between them.
