Grease can form a protective film on the surface of the slide rail, reduce the wear of the slide rail surface, improve the accuracy and life, and also have the excellent performance of reducing resistance, reducing noise, and increasing load capacity. Due to different working requirements, the size of the slide rail is different, so the load that can be borne is also different. The slide rail can set the sliding time, sliding speed, and sliding direction through the controller.

[0003] In practice, it is found that on the same size of slide rails, the greater the viscosity of the grease, the better the noise reduction effect and the greater the resistance. Conversely, the smaller the viscosity of the grease, the worse the noise reduction effect and the smaller the resistance.

[0004] In this regard, how to make the slide rail convenient for grease filling and flow, and how to judge the lubricating performance of the grease through the slide rail so as to use grease with different lubricating performance according to the needs of the enterprise are technical problems that need to be solved.
