    How to Judge Whether the Lubricating Grease Is Metamorphic

    In order to provide better performance during operation, the bearing is usually lubricated by grease , it can reduce the friction and temperature rise of the bearing. If the grease is bad , not only does it not play a role, but it is more detrimental to the use of bearings. The method of judging metamorphic grease are as follows. 1.Oil flow observation. Take two measuring cups , one is filled with lubricating oils, whi...
