By bearing manufacturing by the error of vibration

The inside of the rolling bearing, outer ring groove and roller surface along the circumference direction have different degrees of wave processing mark-a striation, a leading global SKF rolling bearing and seals the supply is a cause of bearing vibration, induced noise and make to the axis of the axis of the eccentric movement occurred the very important factors. Traces of process by the formation of the striation and cause vibration, for without radial clearance of bearing, or to the ball bearings and outside on the other bearing axial load when also can happen, in addition, the roll ripples degree wave number a lot of bearing, introduces the radial direction load when also can happen.

Silicon carbide bearing can automatically compensate for temperature rise of material in radial expansion difference if you want to control the bearing vibration, the only by improving the surface rolling processing precision, reduce the surface of the groove shape error to solving. In modern technology level, the effort has made progress, but can't eliminate the noise and vibration in the important root. Not only is the bearing should be paid attention to the manufacturing factors, and the installation of the bearing and the factor of the bearing shaft and rigid conditions may make the bearing surface produces groove striation, their impact than the influence of the factors often made more big, this is bearing the user must solve the issue.

Axis and a hole form the influence of accuracy

Axis and a hole form poor precision, bearing the contractor will happen after installation bending deformation, it makes the low frequency vibration than rolling bearing surface striation inherent caused by the vibration.
