Rotating machinery is one of the most extensive types of mechanical equipment in engineering applications and the most trouble-prone equipment. Bearings are one of the most basic components in rotating machinery and are the main source of failure. In order to ensure the safety of the equipment and eliminate equipment accidents, it is essential to monitor and diagnose the condition of the bearing. It is the basis for changing the traditional scheduled maintenance for the maintenance of the situation or the maintenance of the maintenance system.

Rockwell Hardness Tester

Rockwell hardness tester is the world's first designed based on the principle of rockwell hardness test, need only unilateral contact sample can test the hardness of the metal rockwell hardness tester, rockwell hardness tester measuring depend on magnetic head adsorption on the steel surface, don't need to support of sample, test precision up to the standard GB/T230, ISO6508, no less than desktop rockwell hardness tester. The Rockwell hardness test was first developed by Americans S.P. rockwell and H.M. Rockwell in 1914. In 1919 and 1921, they improved the design of rockwell hardness tester twice, which established the prototype of modern Rockwell hardness tester. In 1930, Wilson (C.H Wilson) updated the design, so that rockwell Hardness Testing methods and equipment more perfect. Our country has produced touch screen control and numerical display as well as curve display and automatic printing test data rockwell hardness tester. Rockwell hardness testing method is characterized by simple operation, rapid measurement, and can be read directly from dial indicator or optical projection screen or display screen. Along with Brinell and Vickers hardness testing, it has become one of the three most commonly used hardness testing methods
