introduction：For any precise part or instrument，Rust is a fatal flaw。Lets talk about the high precision instrument of the divider，Rust is a big problem after a long time，This will affect the performance of the splitter large reasons，So how can we do rust prevention? First of all，We need to know if the surface of the divider is machined，We can make it smooth and shiny，Do this anti-rust treatment。secondly，Under normal circumstances，Need to keep the divider clean。

introduction：The outer spherical bearing is actually a kind of deep groove ball bearing,It is characterized by its outer diameter against the sphere,Can match the corresponding concave spherical bearing aligning effect。Although its basic performance and deep groove ball bearings should be similar,But because bearings are mainly used for mechanical roughness,When the installation position is incorrect,The axis is neutral to the axis of the hole,Or under conditions of large axial length and deflection,And bearing itself accuracy is not high,Some rough structures,Therefore, the actual performance of the performance comparison in the same specification of deep groove ball bearings play a great discount。 Such as,The outer spherical bearing of the top wire is used for deflection of the large shaft、The stiffness difference between this bearing and seal is on both sides,It can prevent dust intrusion,Keep an eye on the factories that have been loaded Proper lubricant,No need to clean before installation,No need to lubricate,The be

introduction：3DHow will printing change the future of healthcare In recent years，3DPrinters are very popular，The range of applications is endless。In the medical and biotechnology sectors，It can also be used in many areas：Printed organ、Organ allocation、Dispensing drug、Custom prosthetics and more。Lets take a closer look at how its changed the field. Okay。 3DPrinting has been around for years，First applied to manufacturing。This printing technology can produce almost any object by combining different materials。In the past15The middle of the year，3DPrinting has expanded into the medical field，It has contributed groundbreaking medical products such as customized prosthetics and tooth implants。But now，3DPrinting is already available for private medical use。In addition to printing plastic、Metal object，3DPrinting can also print pills and human organs，Make it safer for medical companies to develop、Cheaper drugs。

introduction：Dingge long stroke slide cylinder Long stroke slide cylinder can also be called rodless cylinder，Mainly when the travel is longer，The rod cylinder takes up a large installation space，And there is a large deflection，Affect cylinder position accuracy and stability。Therefore, rodless cylinders are often used when the stroke is long，The rodless cylinder has no piston rod sticking out，Its position output is mainly in the form of sliding table。The application industry of sliding table is very wide，The following Feng Ye Xiaobian will take you to understand the Dingge long travel slide application industry。

introduction：The following Xiaobian we talk about when buying linear bearings，I know about the bearing problem。The purpose is to optimize the selection of bearings，Ensure the excellent quality of bearings。For this reason, we are required to understand the quality of bearings。 Therefore, it is recommended that you understand which linear bearings are good，Pay attention to see whether the white surface of the bearing has muddy oil。 At present, the domestic rust prevention technology has not reached the international standard，Therefore, it is easy to leave a thick oil stain when the bearing body is treated with rust，Such bearings can be sticky in the hand，Many foreign original imported bearings can hardly see traces of anti-rust oil。So by looking at the bearing surface whether there is a muddy oil，It can promote the quality of bearings to a certain extent，Ensure that the purchased bearings have been optimized for rust prevention，It has good anti-rust properties，Of better quality。

introduction：When the linear optical axis is used，The length of this trip is for the normal operation of the machine，It has a relatively large impact。And the linear optical axis travel is too long or too short，Sometimes it will cause the machine to not work normally。In view of this，What causes the linear optical axis travel to be shorter？Next, Xiaobian will give you a brief introduction。 The linear optical axis travel becomes shorter，To a large extent, it is because the number of times the pump truck reverses faster，Optical axis travel becomes shorter。The reason for this，In fact, it is because the pump truck is carrying out low-pressure pumping，The reversals are getting faster and faster，The linear optical shaft travel of the main cylinder is getting shorter and shorter，And you cant see the optical shaft in the washing room。For that matter，To a large extent, it means that there is too much oil in the rodless cavity in the linear optical shaft of the two main oil cylinders，Need to clean up。

introduction：Although the characteristics and performance of grease will be affected by the production process and raw materials。But in fact，Greases cannot be compared or selected on the basis of composition alone。therefore，Performance testing of greases is required，To obtain important information for practical applications。In the last hundred years or so，KOYOBearing grease、The interactions between materials and surfaces have been studied in depth and a great deal of knowledge has been accumulated。 KOYOThis knowledge has been used to establish industry standards for the performance testing of bearing greases。To evaluate the performance of the bearing grease in operation，KOYOMany test standards have been developed for bearings，Such as, Emcor.ROF,ROF+,V2F,R2FandBequietAnd so on。

introduction：Linear bearings are precision parts，Therefore, it is required to be quite careful when using，Even with high-performance bearings，If used improperly，Nor can it achieve the expected performance effect，And easy to cause bearing damage。therefore，The use of bearings should pay attention to matters： one、Keep bearings and their surroundings clean Even the tiny dust invisible to the naked eye enters the bearing，It will also increase bearing wear，Vibration and noise。 two、Be careful when using the installation Strong stamping is not allowed，It is not allowed to hit the bearing directly with the hammer，Pressure transfer through rolling elements is not allowed。 three、Appropriate use、Accurate installation tools Use special tools whenever possible，Avoid things like cloth and staple fibers。
