The hardness of the bearing important it? Rolling hardness Introduction

 The hardness of the Roller bearing detection criteria is a measure of the bearing, the bearing line, every process is very important, bearing production process of each step is very important,
Hardness is an important indicator of Lin bearing, which contact with the material fatigue strength, wear resistance even, elastic limit close relationship with the first, moving from the indirect effect of treatment on the right bearing sweet, soft he bearing of usually bear the load according to the shade manner and size of bearing size and wall thickness of the overall circumstances. Scroll material hardness N Unite Steel fierce appropriate, extraordinary or too small will affect the bearing life is well known, bearing failure modes azelaic to mouth contact with fatigue damage and wear parts 6l in poor or J44 Li Jiao stable precision bearings loss; bearing parts such as Xing lack a certain toughness, compared with people rushing in demand accounted for by the Dutch when will cut hair at first glance due to brittle fracture caused by bearing damage: So, according to the specific circumstances of the bearing and destruction way to determine the bearing hardness in the brake down due to fatigue or wear errands bearings precision bearings good losses of the military member should choose a higher hardness; impulse withstand greater loads on the bearings (such as rolling bearings, railway axis Qi Chinese automotive bearings, etc.) should when forced to reduce the hardness to improve the toughness of the bearing is divided necessary.
In order to stabilize the orbital motion of the cage, bearing rings should be adopted to guide the way and give attention to the guide surface sufficiently lubricated, high-speed conditions of the tapered roller bearing structure given improvements that will guide roller into the L-shaped cage Z-ring ribs guide cage.
