FAG bearings support shaft rotating assembly. Its rings and rolling bodies are precision machined. Angular contact ball bearings in the factory, in order to protect the surface of the raceway and rolling element is not rust, injection of anti-rust oil or antirust grease between the raceway and rolling element. Bearing installation should be carried out before cleaning. Direct cleaning with anti-rust oil sealed bearing available gasoline or kerosene; thick oil or anti-rust oil rust prevention must use light mineral oil, such as 10 # oil or transformer oil heat will melt the grease to cool, then gasoline or kerosene to clean. Both sides with a dust cover or seal, bearings, and joined the grease at the factory, so installation is no longer cleaning. Angular contact ball bearings coated with a rust-proof dual-purpose lubricant lubrication, installation, do not need cleaning. Cleaning the installation process should be to prevent foreign materials from falling into the bearing, between the rolling element and raceway wear and tear, caused by tiny abrasive will increase noise and vibration.
FAG bearing assembly and disassembly in two ways. First, the interference rings pressed into the shaft or pressed into the bearing hole; First, by heating the bearing inner diameter of up or cooling the bearing so that the outer diameter narrowing, angular contact ball bearings are easily installed in the shaft or push the seat hole. When pressurized, mechanical or hydraulic pressure through a dedicated device to force a direct role in the assembly and disassembly of the seat, and never allow the loading and unloading force to pass through the rolling. Otherwise it will create the raceway and the rolling surface indentation, increased noise and vibration, resulting in the destruction. If the heating or cooling methods for assembly and disassembly, heating temperature, or cooling temperature should be strictly controlled. FAG bearing strength of the work surface by the structure of the metal surface microstructure, the temperature is too high will cause the tempering effect; can cause embrittlement of the metal surface temperature over the bottom. Heating temperature is usually not more than 100 ° C, the minimum cooling temperature shall not be the end of the minus 50 ℃. Also to be considered should be evenly heated.
Practice has proved that the improper installation, FAG Bearings is one of the reasons lead to premature bearing damage. Disassembly with interference rings is a very difficult thing in the design of supports, we must consider how the angular contact ball bearing assembly and disassembly and ease of assembly and disassembly. Assembly and disassembly of large bearings of heavy machinery often need to design special equipment. If the demolition of the high pressure oil need the appropriate design of oil, pipeline and pump.
