IKO import bearing performance of the material after heat treatment should have

Contact fatigue damage is the main form of IKO import bearing normal damage. Rolling bearing during operation, in IKO import roller rolling bearing 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. Began to appear after peeling rolling bearings will IKO import bearing vibration and noise caused by increasing operating temperature has risen sharply, IKO import bearing finally damage, the damage form is called the contact fatigue damage. Therefore, IKO import bearings 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. IKO import bearings rolling bearing in the existence of the sliding friction inevitably IKO import bearing wear parts. If the bearing steel wear resistance is poor, the rolling bearing will prematurely due to abrasion loss due to the rotation accuracy or precision increase IKO import bearing vibration, reduce the service life. Therefore, IKO bearing steel import requirements should be high wear resistance. The basic requirements of rolling bearing on the material depends largely on IKO import bearing performance. 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, IKO import bearings and make import bearings IKO precision loss due to friction and wear. In addition, there is crack, indentation, corrosion causes such as abnormal damage IKO import bearings. 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.
