SKF bearing performance of the material after heat treatment should have

Contact fatigue damage is the main form of SKF bearing normal damage. Rolling bearing during operation, in SKF bearing roller rolling between the inner and outer ring raceway, the contact part under periodical alternating load, the bulls can reach hundreds of thousands of times per minute, in under the action of repeated periodic alternating stress, surface contact fatigue spalling. Rolling SKF bearing began to appear after peeling will SKF bearing vibration and noise caused by increasing operating temperature has risen sharply, SKF bearing finally is damaged, the damage form is called the contact fatigue damage. Therefore, SKF bearing for rolling bearing steel should have high contact fatigue strength. Rolling bearing is normal work, in addition to outside the rolling friction, accompanied by sliding friction. Main parts of the sliding friction is: between the rolling element and raceway contact surface, the contact area between the rolling element and cage pocket hole, cage and the guide ring between rim and roller end face and ring lead guard, etc. The existence of the sliding friction in rolling bearings SKF bearing inevitably SKF bearing wear parts. If the wear resistance is poor, SKF bearing steel rolling SKF bearing will prematurely due to abrasion loss due to the rotation accuracy or precision SKF bearing vibration increase, reduce the service life. Therefore, SKF bearing steel requirements should be high wear resistance. The basic requirements of rolling bearing on the material depends largely on the performance of SKF bearing. Choose rolling bearing materials is more appropriate are made, has a great influence on the its using performance and life will be. Under normal circumstances, the rolling bearing is the main damage form under the action of alternating stress fatigue spalling, SKF bearing and the SKF bearing precision loss due to friction and wear. In addition, there is crack, indentation, corrosion causes such as SKF bearing abnormal damage. Rolling bearing, therefore, should have high ability to resist plastic deformation, less friction and wear, good rotation accuracy, good dimensional accuracy and stability, as well as the long contact fatigue life.
