The influence of the smelting of steel precision bearing life and size requirements

Smelting effect on the service life of bearing steel precision and dimensional requirements source: bearing | last updated: - 2020 09 - 11 affecting the precision of the bearing and the life of the way to the installation of automatic self-aligning ball bearing is correct, directly affecting the service life of bearing used in precision, and performance. ( 1) When cleaning a lot of automatic self-aligning ball bearing, first with a temperature of 90 ~ 100 ℃ heat oil pour hot to melt encapsulated oil, at the same time with seamless all mouth and no net exfoliation tools to dig old oil, then pour hot a few minutes, then rinse with kerosene oil, clean with gasoline again finally. On film gloves should be worn after washing clean, automatically self-aligning ball bearing on the worktable of dry clean cloth or paper. ( 2) Before automatic self-aligning ball bearing installation, should use the appropriate measuring tools according to the provisions of the technical requirements on the design drawing check the shaft and hole and machining quality of parts ( Such as dimensional accuracy and shape accuracy and surface roughness, etc. ) 。 ( 3) When installed in the open the packaging automatic self-aligning ball bearing, put it into the liquids such as gasoline with handle gently gently turning, to ensure the cage, encapsulated oil on the surface of the rolling element and raceway thoroughly washed clean. The size of the bearing steel smelting with high precision demands of rolling bearing steel steel dimension precision is higher, this is because most are through pressure bearing parts molding. In order to save material and improve labor productivity, the vast majority of 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 bearing parts, also easy to cause damage of equipment and dies.
