A day to learn: bearing is by that aspect and fever

A day to learn: is that aspect and fever are working in the general machinery can produce hot, hot, not because of mechanical operation faster or operation for a long time, and drive the bearing parts with fever, caused two friction more cause fever, so normally fever is caused by what reason? Engineers to explain today the bearing is by that aspect and fever. 1, the pre-tightening force is too large, smaller clearance; 2, lubricating oil or grease selection is not reasonable, lubrication system configuration is reasonable, heat dissipation is not good; 3, what is the temperature reached, whether within the scope of the permit; 4, bearing choice is correct, whether beyond bearing design performance; 5, the bearing precision meets the requirements; If there is damage; 6, using the environment influence on bearing, such as dust particles can enter the bearing; 7, when installation if NMB bearing pre-tightening force of uniform. Pro, bearing heating means that you understand the above? If you don't understand can contact our online engineer, our engineer except holidays don't online 24 hours service for you all the way, for you to answer is our biggest honor ~ thank you for your coming! ！
