The bearing shaft bearing system requires both a high rigidity, and the quality requirements to be as light as possible, To overcome this contradiction, can take measures such as reducing the surface roughness and improve surface hardening to improve the supporting rigidity of the hollow shaft in order to reduce the quality of the system, etc..
(1) prior to the bearing mounting, the appropriate measurement tool should press on the technical requirements in the design drawings, the inspection shaft and the housing bore as well as the quality of the relevant parts of the processing (such as the dimensional accuracy and shape accuracy and surface roughness, etc.).
(2) 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 LNSERTED bearing not difficult to install and the installation location correct, and solid particles, such as falling into the bearing will be from the abrasive LNSERTED bearing rotation will work surface rubs or scrapes bearing, so 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.
(3) The mounting surface should be cleaned with a clean gasoline, kerosene, toluene or xylene solution clean, and dry with a clean cloth and then coated with a thin layer of lubricant, it will give the the installation operation more convenient.
(4) Pro installation open LNSERTED the bearing 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.
(5) cleaning a large number of bearings, the first temperature is 90 ~ 100 ℃ hot oil poured hot so that the encapsulated oil is melted, Seamless mouth at the same time exclude off the cuttings tools for digging net all of the old oil, and then poured hot minutes, and then go flush with kerosene oil and clean again, and finally then gasoline. Cleaning clean, the film should wear gloves LNSERTED bearing on the workbench clean cloth or paper to dry.
(6) Note that with sealed bearings can not be cleaned with this Act, the interior of the seal should not be cleaned intact.
