GEWZ-ES-2RS Radial Spherical Plain Bearings Features

Spherical plain bearing noise is sliding friction between metal to produce sharp scream, even if the bearing temperature rise is not high, is little effect on bearing life and grease life, also does not affect the rotation, but not sweet sound disturbing, especially the noise are common bear radial load bearing, bearing radial clearance when the big easy generation, also in grease lubrication, oil lubrication is relatively rare.With the increase of bearing size, it decreases and often appears in a certain speed range.Winter often occurs, is generally irregular, and unpredictable, and with the amount of fat and performance, installation and operating conditions.This noise can be prevented by reducing the radial clearance of the bearing and by using a shallow outer ring raceway structure.This noise is caused by the free vibration of the cage and its collision with the rolling body or the ring during the bearing rotation.It may appear in all kinds of bearings, but its sound pressure level is not too high and is low frequency.Stamping cage and plastic cage can be produced, whether it is thin oil or grease lubrication will appear, when the outer ring bears the moment of the most prone to occur, the radial clearance is easy to appear.It is very difficult to completely eliminate the sound of the retainer because of the inevitable existence of the gap between the ball pocket of the retainer and the gap between the retainer and the ring of the retainer in the finished bearing. However, it can be improved by reducing the assembly error and optimizing the reasonable gap and the retainer's channeling momentum.There is also a special sound of retainers due to the friction between the retainer and the guide surface of other bearing parts caused by the retainer self-excited vibration caused by the noise.The punching cage of deep groove ball bearing is relatively thin, the bending stiffness in radial and axial plane is low, and the overall stability is poor.When the bearing is under radial load and the grease performance is poor, the cracking noise will be heard at the initial stage of operation. This is mainly due to the noise caused by the sudden acceleration of the rolling body after it leaves the load area and collides with the cage. Such collision noise is inevitable but will disappear after a period of operation.
