introduction：2）It is necessary to preheat the bearing seat during the initial production process，Prevent the appearance of turtle cracks caused by the sudden encounter of hot metal liquid in the cold bearing seat，A more cluttered bearing seat can be used with a blowtorch，Liquefied gas，Good conditions with mold temperature machine，Simpler housings can be preheated using slow injection。 1、Use of bearing housing cooling system。Bearing seat cooling water not only extends the service life of the bearing seat when used correctly，And improve production efficiency。We often overlook its importance in actual production，To save the trouble、Cost saving，Some companies eliminate the need for cooling systems，This has caused serious consequences。Bearing seat in use，If the mold temperature is too high，It is easy to make the surface of the mold core appear turtle cracks early，It also has an impact on the products produced。The use of cooling water can also reduce the loss of the ejector rod and core caused by the overheating of the bearing

introduction：one、Hot oil cleaning method due to long use，Soft dry oil or rust resistant paste hardening bearing，Should be submerged in100—200℃In the hot oil，Clamp the bearing with pliers，Brush the grease off the bearing with a brush。Soft dry oil or anti-rust paste is heated to100—200℃Ready to melt，Its easy to wash through the cracks in the bearings。Sometimes just shake the bearing in the oil several times。Oil can also flow through the crevices。When cleaning the radial spherical bearings of old motors or imported motors，You should put the ball、Bead holder、The inner ring is turned laterally out of the outer ring and then immersed in the hot oil，Short cylindrical roller bearings should also be cleaned when the roller、Bead holder、Inner ring and outer ring detached。 In hot oil cleaning，The temperature of the oil should not exceed20℃。If direct heating with open flame，Care should be taken to prevent the oil from burning，The bearing should be suspended in the oil pan、The bottom will cause overheating and reduce hardness。

introduction：ABBABall screw is due to rolling contact with minimal starting friction、Sensitive to input and able to act accurately，So you can fine-tune tiny movements。Sliding screws turn heavier if the axial clearance becomes smaller，The steel ball is in point contact with the screw groove，Therefore, even in the pre-loaded state, smooth action can be achieved。 2、Select the appropriate prepressure to obtain high rigidity ABBABall screws are available through a selection of spacers of various thicknesses，The preload on both nuts can be finely adjusted，High rigidity can be obtained easily by selecting appropriate prepressure。In addition，Select a single nut to achieve no backlash(Light precompression)The state of。

introduction：1、Cross cylindrical roller bearing oil bath smooth Oil bath smoothing is a common smoothing method in thin wall cross roller bearings，Low fit、Smooth medium speed bearing。willNSKPart of the bearing is immersed in the oil tank，Smooth is carried by rotating bearing parts，Then flow back to the tank oil level should be slightly lower than the center of the low rolling body。 2、Cross cylindrical roller bearings drip smooth Drip smooth is suitable for thrust cylindrical roller bearing components that require a quantitative supply of smooth，The amount of oil drops is individual3-8One drop per second is appropriate，Too much oil will cause the bearing temperature to increase。 3、Cross cylindrical roller bearings have smooth circulating oil Pump the filter to the conveyorNSKBearing components，It is used after smooth filtering and cooling after bearing。Because the cycle takes away certain heat，This method can be used for bearing parts with higher speed because the bearing is cooled。 4、Spray smooth of cross cylindrical roll
