Imported bearing with how

Imported bearing with how as a salesman is not you just go to the product to sell, how to investigate products in the user's point of view feeling, good or bad? Benefits: what kind of products you give him? In some time ago I sell out of a batch of cargo are high bearing and imported bearing, the customer is have their own factories, have done, of course is our net price and quality are guaranteed, online statement also false a compensate ten. But no matter how many are there will be some problems, the same to people in life you can not do without the ailment, what's more, a component in the daily operation, so often back to ask is a must. Of course there is a problem is to use? How much is the quality of output some more concerns. Below we engineer concluded, refer to the following. 1, the quality of raw materials. Bearing raw materials are mainly high quality bearing steel and electrolytic copper used in the production of bearing cage and ball black cast iron, the good and bad of raw materials, and determines the quality of bearing better. 2, the hot working technology. Bearing can work in different environments under heavy load and high speed, mainly bearing on the basis of guarantee the quality of steel, in the process of machining parts of bearing scientific and reasonable heat treatment process, ensure the hardness in HRC60 - Between 64, making the bearing with both high strength in use, and has a strong toughness, so as to ensure the inner quality of bearing. 3, the accuracy of bearing. The precision of the bearing is the important basis to ensure the quality of bearing, mainly including the size tolerance, rotating accuracy, beating the radial, axial, clearance size and vibration value. 4, bearing test. Bearing detection is very important steps in the process of bearing manufacturing, mainly including parts in the process of detection, and the overall detection of bearing assembly before delivery.
