Overview: Temperature That The Bearing Can Withstand

Overview

The size of the bearing changes due to the change of the internal structure of the material during operation. Temperature These changes are affected by temperature, time and pressure.

The bearing data shall be subject to special heat treatment (stability) Temperature process to prevent  impermissible dimensional changes due to structural changes during operation. The heat stability treatment grade of the bearing is as follows:

Source of vibration and noise of SKF Bearing

Bearing Torque, Load And Service Life

Question 1: what are the main factors of SKF Bearing Vibration?

Answer 1: SKF Bearing Vibration mainly comes from two sources:

First, the natural vibration of SKF Bearing caused by external excitation of SKF shaft refers to the natural Temperature vibration of inner ring, outer ring, rolling element and cage of SKF Bearing

The second is the forced vibration caused by the mutual contact and collision of moving parts, including the forced vibration caused by the Overview Temperature fact that the rolling element is not an ideal sphere, the motion track of the contact point of the inner and outer channels is not an ideal circle (roundness and waviness),

the rolling surface is not an ideal smooth surface (roughness), the Temperature collision between the rolling element and the cage in motion and the impurities in the lubricant, Overview Vibration and sound are closely related.

For general SKF bearings, it is recommended to concentrate limited human and financial resources to Overview Temperature control the vibration of SKF bearings. It is not appropriate to establish a separate quality standard for noise. Of course, according to foreign experience, for special products,

such as SKF bearings in computer hard disk drive system and video recorder optical disk drive system, it is not convenient to use vibration Overview assessment, noise measurement Temperature method standards can be formulated for assessment.
