Installation and adjustment of the low-noise bearing grouping method can also be emulated long-life bearing, so that interference with the more consistent size, the bearing clearance is also more consistent, and you want to take interference with a smaller value to the extent possible, in order to ensure bearing raceway deformation is small, so that the rolling elements caused by noise becomes small.

Great clearance relation to noise, the ideal state is when the bearing is in operation the highest temperature state, clearance values ??exactly zero. Analyzing clearance is too big methods are: a stationary state for axial displacement of the shaft, the larger the amplitude of its reciprocation, and a great and muddy noise during operation.

If you issue nasty shrill whistling during the operation, then much bearing preload, bearing larger preloaded should be slightly relaxed pretension level. If the clearance is too large, it can make two bearing ring axially slightly relative deviation: only reduces the clearance, but also increases the axial stiffness, bearing noise can be reduced.

When rolling the zone will slip into the no-load or ran for about, then it will increase the noise will cause wear, while the small clearance and large axial stiffness can eliminate this phenomenon. But clearance is not too small, to avoid overheating and shortened life expectancy.

Sometimes, because of the host's operating temperature range is large, or the size of the shaft and housing bore discrete large, once it is set can not get a more appropriate clearance, in this case, the outer ring of the bearing pre elastic constant pressure tight Act
