The motion characteristics and heat generation mechanism for high speed precision angular contact ball bear-ings are analyzed theoretically.Taking H7014C/HQ1 as an object,the experiments are carried out under different rota-tional speed,axial pre-tightening force and amount of lubricating oil.The results show that the rotational speed has marked influence on temperature rise of bearing,the reference value for optimum preload and amount of lubricating oil are given at the same time.
