The self-aligning ball bearing is installed correctly, directly affect the precision bearings, life and performance.
(1) cleaning a large number of self-aligning ball bearing, first with a temperature of 90 ~ 100 ℃ hot oil poured hot to package oil melted, seamless mouth at the same time and not drop crumbs the tools dug net all the old oil, then pour hot In a few minutes, then go flush with kerosene oil and clean again, and finally then gasoline. Washing clean, put on the film the gloves will automatically aligning ball bearings on the the workbench clean cloth or paper to dry.
(2) Before self-aligning ball bearings installed, you should use appropriate measurement tools on the design drawings and technical requirements, check the shaft and the housing bore and the relevant parts of the processing quality (such as dimensional accuracy, shape accuracy and surface roughness ).
(3) Pro installation open automatically aligning ball bearings package, it gently rotate the hand immersed in the above-mentioned liquid such as gasoline, to ensure the cage, rolling element and raceway surface encapsulated oil thoroughly cleaned.
(4) mounting surface should be cleaned with a clean gasoline, kerosene, toluene or xylene solution clean and wipe dry with a clean cloth, and then coated with a thin layer of lubricant, it will give the the installation operation more convenient.
(5) Note that with sealed self-aligning ball bearings can not be cleaned with this Act, the interior of the seal should not be cleaned intact.
(6) If the hole of shaft and bearing assembly on the surface bumps, burrs, rust, or solid particles (such as debris, sand, mud), exists, will not only automatically aligning ball bearing installation difficulties and make the installation location correct and solid particles, such as falling into the bearing will the abrasive, when the self-aligning ball bearing rotary grinding work surface wounds or abrasions bearing before installation must be carefully inspected, as found in the above-mentioned defects should be amended. For example, the use of oil file to remove the burrs, raised touch marks, rust and polish with fine emery cloth, clean the solid particles, dirt, etc. Another example.
