 First, the shaker SKF bearing peripheral demolition 
 Demolition of interference fit of the outer circumference of the shell in advance to set several outer extrusion screw with a screwdriver, tighten the screw side equally. Side of the demolition. These screw holes are usually covered with blind plug, vibrating screen, tapered roller bearings, such as separation of bearings, set several incisions in the housing block on the shoulders, this time to use the pads, then press demolition or gently tapping with slow slow demolition. 
 Second, the shaker demolition of the cylindrical bore bearings 
 Remove the inner ring, in fact, using the press to remove the pull out the most simple. At this time, pay attention to the inner ring to withstand the pulling force. Large vibrating screen bearing inner ring disassembly by hydraulic method. Oil pressure through the hole in the shaft, so that easy to pull. The width of SKF bearings hydraulic drawing fixtures and the demolition job. NU type, NJ type cylindrical roller shaker bearing inner ring disassembly by induction heating. Local heating in a short period of time, so that the inner expansion after drawing. 
 Third, the tapered bore bearing removal 
 In the demolition of the small SKF import bearing with adapter sleeve that support good bearing on the need to tighten the inner circle, back to a few times and then give the nut, pad or a hammer to beat the demolition. 
 To sum up, the undissolved carbides GCr15 steel after quenching at about 7% of retained austenite (cryptocrystalline martensite, the average carbon content of about 0.55%) is the best organization in about 9%. Moreover, when the original tissue carbide is small, evenly distributed, reliable control of the level of microstructure, is conducive to high mechanical properties, which has a high service life. It should be noted, has a small dispersion of the original organization of the distribution of carbides, quenching the heat insulation, the small amount of undissolved carbides gathering grew to coarsening. Therefore, for the original organization to have such parts SKF bearings quenching time not too long, rapid heating, quenching austenite process will receive the higher comprehensive mechanical properties.

 To make the SKF bearing parts quenched surface residues in a large compressive stress after tempering, quenching the pass into the atmosphere of carburizing or nitriding, short-term surface carburizing or nitriding. Due to heating of the steel quenching austenite actual carbon content is not high, well below the equilibrium concentration of the phase diagram shows so you can suck carbon (or nitrogen). Austenite containing carbon or nitrogen, its Ms lower surface than the inner and center quenching martensite transformation occurs, resulting in a larger residual stress. After GCrl5 steel Hardening of the carburizing atmosphere and non-carburizing atmosphere (low temperature tempering) treatment, the contact fatigue test can be seen that the surface carburization of life not carburization increased 1.5 fold. The reason is carburized parts surface has a larger residual stress. 
 (2) the impact sound of the rolling elements and the larger models of the control method of ball bearings or cylindrical roller one-way bearing in the low-speed operation under pure radial load, due to the centrifugal force of the rolling element is smaller in the non-load the rolling body will impact the cage or raceway noise. But as the speed increases, the sound will disappear. The rolling element of impact sound control methods are: appropriate to reduce the radial clearance, the use of reasonable structure, materials submissive cage bearing.

 3 the jarring sound of one-way bearing and its control method jarring sound of the cylindrical roller one-way bearing harsh metal grinding sound in all occasions that may occur, in most cases took place in greased large models bearing, and in the more susceptible to performance degradation of the base oil grease, almost no oil lubrication. In addition, during the winter are more prone to prone when under pure radial load, radial clearance of the occasion, and with different model size, prone to a particular speed range, both on a continuum will intermittently appear. External ring raceway to take special processing methods to prevent jarring sound, if necessary, choose this one-way bearing, or appropriate to reduce the radial bearing clearance, the use of the excellent performance of the grease and improve the match with a one-way bearing parts of the rigidity.
