Because the economic legal system of socialist shopping malls was not perfect at the time; and many consumers did not know how to distinguish the quality of the bearings; perhaps because of the temptation of low prices; the small manufacturers bearing and counterfeit bearings filled the mall.
According to statistics, at the time, the market share of small manufacturers' bearings and shoddy bearings exceeded 60%; in some areas, the occupancy rate even exceeded 80%. However, the inferior bearing has great harm due to its inherent quality defects and low precision. ; then bring a huge loss to the user.
1. Because of the constraints of raw materials; the hardness of the inferior bearing does not meet the national demand. In the application, it will show deformation and other conditions; then affect its service life; harm other parts of the machine. Especially some high temperature bearings and high speed bearings; bearing hardness Directly affect its service life and operational safety.
2, because of the small manufacturers and underground factories' bonfire skills; the inferior bearing cylinder bonfire heat temperature is not uniform; then it affects the precision of the bearing; the deformation and other conditions.
3, its grand skill constraints directly affect the precision of these bearings; make this problem an insurmountable flaw; and the precision distance not only directly harms the parts of the machine; it also makes bearing loading and unloading a rather cumbersome work; Can not be installed; can not be unloaded; directly harm the machine, delay work hours.
4, some small manufacturers and illegal processing plants in order to reduce costs; the use of defective steel, Ma Steel, carbon steel and other raw materials; together in the production process to reduce the process; these products in the process of simple problems; even directly make the machine equipment In order to protect their own rights and interests; consumers not only enhance their own legal awareness; but also learn to identify and select genuine bearings; and then prevent the formation of uncorrectable damage to the equipment.
