Bearings are key basic parts in the field of industrial equipment manufacturing. The higher the hardness of the bearing, the more wear-resistant the bearing is, and the higher the material strength is, so as to ensure that the bearing can withstand greater loads and operate for longer periods of time. Therefore, its internal hardness is of great significance to its service life and quality.
For the hardness test of steel and non-ferrous metal bearing parts after quenching and tempering and finished bearing parts and non-ferrous metal bearing parts, the main test methods include Rockwell hardness test method, Vickers hardness test method, tensile strength test method and Leeb hardness test method, etc. Among them, the first two methods are more systematic and common in the test, and the Brinell method is also a relatively simple and common method, because its test indentation is large and less used.
The Rockwell hardness test method is widely used in the bearing industry, and its main features are simple and fast.
The touch screen digital display Rockwell hardness tester is simple to operate. It only needs to load the initial test force and the hardness tester will automatically obtain the hardness value.
The Vickers hardness test method is aimed at the hardness test of the bearing shaft and the spherical roller of the bearing. It needs to cut and make a sample test to obtain the Vickers hardness value.
