Fag bearings are assemblies that support shaft rotation. Fag Angular Contact Ball Bearing The ferrule and rolling element are precision machined. Before delivery of angular contact ball bearing, in order to protect the surface of raceway and rolling element from corrosion, antirust oil or antirust grease is injected between raceway and rolling element.
Therefore, the bearing should be cleaned before installation. Bearings sealed with antirust oil can be directly cleaned with gasoline or kerosene; If thick oil or antirust grease is used for rust prevention, Fag Angular Contact Ball Bearing light mineral oil, such as 10# engine oil or transformer oil, shall be used for heating, melting and cooling the grease, and then cleaned with gasoline or kerosene.
Bearings with dust covers or sealing rings on both sides have been added with grease before delivery, so they do not need to be cleaned during installation. Angular contact ball bearings coated with Fag Angular Contact Ball Bearing lubricating and antirust dual-purpose lubricating oil do not need to be cleaned during installation.
During cleaning and installation, foreign matters shall be strictly prevented from falling into the bearing, because small abrasive particles will cause wear Fag Angular Contact Ball Bearing between the rolling element and the raceway, increase noise and vibration.
First, press the interference ring into the shaft or into the bearing seat hole; First, the inner diameter of the bearing is increased by Fag Angular Contact Ball Bearing heating the bearing, or the outer diameter of the bearing is reduced by cooling the bearing, so that the angular contact ball bearing can be easily installed on the shaft or pushed into the seat hole.
When the pressurization method is adopted, the mechanical force or hydraulic pressure will directly act on the assembled and disassembled seat ring through a special device, Fag Angular Contact Ball Bearing and the loading and unloading force is never allowed to be transmitted through the rolling element. Otherwise, it will cause indentation on the surface of raceway and rolling element, increase noise and vibration and cause damage.
If heating or cooling methods are used for assembly and disassembly, the heating temperature or cooling temperature shall be strictly controlled. Because the strength of fag bearing working surface is Fag Angular Contact Ball Bearing affected by the metallographic structure of metal surface, too high temperature will cause tempering effect; Over low temperature will cause embrittlement of metal surface.
Practice has proved that improper installation of fag bearing is one of the reasons for premature bearing damage. It is very difficult to assemble and disassemble the ferrule with interference. Therefore, when designing the support, we must consider how to assemble and disassemble the angular contact ball bearing and how to facilitate the assembly and disassembly.
For the assembly and disassembly of large bearings in heavy machinery, it is often necessary to design special equipment. Fag Angular Contact Ball Bearing If the high-pressure oil is disassembled, the oil circuit, pipeline and pump shall be designed accordingly.
