Size requirements and use non-standard bearing steel smelting device specificity analysis

Non-standard bearing steel smelting concreteness size requirements and use plant sources: bearing | last updated: - 2020 09 - 16 the size of the non-standard bearing steel smelting with high precision demands of non-standard bearing steel rolling steel dimension precision is higher, this is because most are through pressure molding non-standard bearing parts. In order to save material and improve labor productivity, the vast majority of non-standard bearing ring have been forging forming, steel ball is through cold heading or hot forming, small size of the roller is also through the cold heading forming. If the size of the steel precision is not high, will not be able to accurately calculate the expected size and weight, and cannot ensure the quality of non-standard bearing parts of the product, also easy to cause damage of equipment and dies. The use of non-standard bearing device specificity analysis dynamic pressure bearing, non-standard bearing cavity layout depth is suitable for high speed light load of machine tool spindle; Such as the M1432 cylindrical grinding, grinding MGA6025 things, etc. 2. Kong Shihuan saves the cavity depth dynamic pressure bearing: applicable to medium speed load of machine tool spindle; Such as MG1432 cylindrical grinding, MM7150 flat grinding, M1080 centerless grinding, roll grinding, etc. 3. Dynamic pressure bearing: column pin type in response to apply to change the large machine tool spindle load and speed. 4. Conical hydrostatic bearing: suitable for high speed grinding head spindle system ( Such as 2110 circular grinding head) Channel grinder, electric spindle, and inside.
