In order to ensure the performance of the FAG bearings, as well as to prevent premature bearing failure, must be taken to correct the installation of ball bearings and roller bearings and to keep the environment clean. And other precision compo nents, installation of rolling bearings should try to be careful. Select the correct installation method and using the correct installation tools are equally important. Can provide a series of maintenance products, suitable for mounting and dismounting of bearings, mechanical and hydraulic tools and heating equipment, as well as bearing maintenance products. This series of products to make the work more simple and quick assembly and disassembly of bearings, and can achieve the desired results.
To try to extend the working life of FAG bearings imported bearings must be properly installed, work in this area is not imaginary simple, especially oversize bearings. To ensure correct installation and maintenance of bearings, timing to offer a variety of seminars and hands-on training course part of the service, which is a reliability system can provide. Need around the company can also provide installation and maintenance recommendations.stainless steel bearings
Installation sites
Install the bearings should be in a dry, dust-free room, and should be kept away from the metal processing equipment or other metal debris and dust generated. (Larger bearings often encounter the situation) must be installed in the unprotected environment bearing, bearings and related components must take appropriate measures to protect against dust or moisture contamination. Until the installation is complete, such as the use of packaging wax paper or foil bearings and related components covered or wrapped up.
Installation and preparatory work before the demolition
Before installation, should be ready all the necessary parts, tools, equipment, and related data and so on. Also carefully study the drawings or instructions, to determine the correct installation sequence for different parts. Be careful to check parts of the bearing housing, shaft, seal and bearing arrangemen t to ensure that the mating surfaces clean and good special inspection should also screw holes, conduit and trench to prevent has some processing residues, after casting the bearing, should ensure that no core sand to stay on the surface without machining, there is no addition to all burrs.china bearing
Tolerance range, bearing all parts dimensional tolerances and tolerances on shape, check FAG bearings configuration related components necessary to achieve the required accuracy and compliance before they can play their due performance. Cylindrical journal and housing bore diameter, generally with a micrometer or diameter micrometer in both cross-sectional and four different locations to measure. Journal taper can be used to look around, the special taper gauge or sine measured.
1, the mounting surface and installation site requirements?
If iron filings, burrs, dust and other foreign matter into F AG Bearings, will make bearings produce noise and vibration during operation and even damage the raceways and rolling elements. So, before installing the bearing, you must make sure that the mounting surface and installation environment clean.
2, bearing installation must be cleaned before it?
The bearing surface is coated with anti-rust oil, you must be carefully cleaned with clean gasoline or kerosene, and then coated with a clean, high-quality or high-speed high-temperature grease before installation.
The cleanliness of the bearing life and vibration noise is very large.
In particular, we want to remind you: fully enclosed bearings should be cleaned refueling.
3, how to choose the grease?
Lubrication FAG bearing operation and life has a very important influence.
Here is a brief introduction to you to select the general principles of the grease. Grease base oil, thickener a nd additives made of different types and different brands of the same type of grease performance varied widely, the rotation limit allowed, important to note that in the choice.
Grease performance is mainly decided by the base oil.
Usually a low viscosity base oil suitable for low temperature, high speed; high viscosity suitable for high temperature, high load.
Thickener also relates to the lubricating properties, the water resistance of the the water resistance decision grease thickeners.
In principle, the different brands of grease can not be mixed, Moreover, even if the same kind of grease thickener, also with each other because of different additives adversely affect.
