Ball Bearings 6900 Series

Ball Bearings 6900 Series
Deep groove ball bearing has a very important position in the mechanical parts, in order to make the ball bearing work normally, using the correct installation method is crucial.The bearing cannot be used due to the installation problems, which may occur during the operation. The bearing is initially determined in the design stage for the selection and installation and disassembly methods of specific applications.The installation process should be carried out as far as possible in a clean and dust-free space, not in dusty production machines.

Ball Bearings 6900 Series Features

Dust and debris affect the internal clearance of the bearing and the precise alignment of the shaft or bearing.The tiny dust can affect the outer diameter of the outer ring, and even cause a tight fit to create gaps.This will cause the outer ring of the bearing to rotate in an uncircular space.The dust on the shaft causes the shaft to wear away from the sealing element and results in oil leakage.Dust mixed with lubricating oil forms an abrasive mixture that results in bearing wear.

Do not remove the original packing of the new bearing until it is installed.The new bearings are thoroughly coated with a compound antirust coating, which insulates air, water and rust.The coating used by most bearing manufacturers is not easily eliminated as it is compatible with almost all oil lubricants.When using synthetic oil and synthetic grease, the protective layer of the compound must be removed.However, with the use of synthetic hydrocarbon oil and grease, the composite coating is not necessary to be removed.Bearings are wrapped in heavy, waterproof laminated paper.Care should be taken not to drop or grip the bearing.Bearings should not be exposed to a variable temperature environment that may lead to condensation.Unnecessary.Fingerprints can be a starting point for rust.There are three basic methods for bearing assembly: cold assembly, hot assembly and hydraulic assembly.
