The outer ring of the main roller is in contact with the steel groove of the doorframe. The inner diameter of the bearing is fixed on the fork bracket to realize up and down movement under the tension of the chain. The bearing mainly plays the role of guiding and transferring the component forces in the horizontal direction. The product adopts the current industry-advanced ultimate load design scheme, which increases the rated load of general bearings by 5%.Using high quality bearing steel C&U3 and high speed forging process, the actual bearing capacity is usually about 5% larger than its rated load, and the actual life is usually 5 ~ 8 times of its rated life. Double hardness process design: the overall quenching and tempering treatment, so that the bearing ring has a certain toughness and enough strength, with excellent comprehensive mechanical properties, the tempering hardness of 30 ~ 42HRC, after quenching and tempering on raceway induction hardening treatment, so that the raceway hardness of 58 ~ 62HRC, raceway hardening layer 3mm above.Then de-stress and temper.The contact fatigue strength between the bearing raceway and the ball is guaranteed, thus ensuring the bearing life.Because the bearing surface hardness is relatively low, it can effectively reduce the wear of the forklift door frame and improve the life of the door frame. The product surface adopts advanced phosphating special treatment, which makes the product surface form a layer of dense, uniform, good adhesion, strong corrosion resistance of passivation phosphating film, so as to enhance the binding force between the bearing and the door frame, improve the bearing surface corrosion resistance, wear resistance and lubrication performance.Forklift Bearing factory website:http://www.yongqiangbearing.com/automobile-bearing/forklift-bearing/
