Effect of grease quality on the use of fag with flanged linear bearings

Fag Bearings has the world's most mature and comprehensive range of high-precision bearings for machine tool spindles, representing the highest level of performance. Bearings can provide bearings for the design of almost all spindles on the market. Therefore, the choice of flanged linear bearings can meet the requirements of most specific applications. The contact shape of this type of fag bearing, the choice of materials, the best surface quality, and other characteristics of lubricant feeding have the following advantages:
High precision
2. Excellent high speed performance
3. High stiffness
4. Good seismic performance.
Grease plays an important role in the entire fag bearing system. Whether grease lubrication or oil lubrication has a large impact on system cost. Lubricants must undergo a rigorous validation process prior to use. Calculations and suitability tests for specific application requirements, such as the temperature performance and run-in performance of high-speed rotating spindles, are important throughout the process. The result of this complex process is that the technical parameters of the lubricant to be verified are verified and its exact suitability is ensured by continuous testing.
The metallurgical quality of flanged linear bearing materials used to be a major factor affecting the early failure of fag bearings. With the advancement of metallurgical technologies (such as vacuum degassing of bearing steels), the quality of raw materials has improved. The proportion of raw material quality factors in bearing failure analysis has dropped significantly, but it is still one of the main factors affecting bearing failure. The proper selection of materials is still a factor that must be considered in bearing failure analysis.
The fag bearing is a structure with or without a cage. Among them, large-sized bearings are generally required to bear a large load, often without a cage, but filled with rolling elements between the inner and outer raceways. Most small and medium-sized flanged linear bearings are equipped with cages.
In the fag bearing process, how the outer ring, inner ring, rolling element and cage of the bearing are assembled. Simply put, the inner and outer rings of the bearing are placed first, the inner ring is placed sideways, then the rolling elements are placed (on one side), then the position of the rolling elements is adjusted, and finally, the cage is placed. Now everyone knows that there is also a cage involved in the processing of flanged linear bearings. What is the main function of the bearing cage?
