The male and female Screws are mainly used in computer, circuit board and other industries. When one end is screwed into the locked object, the hexagonal column is exposed, which can fix or isolate other objects. The male and female screws are assembled on the computer host. The external thread connects the main board inside the host. The internal thread separates the main board from the sheet metal shell. The terminal line to be connected is connected with a screw from the internal thread of the sheet metal shell and the male and female copper column.

Rolling bearings are many mechanical parts produced; and the precision of production is very strict; the degree of specialization of skills is very high; therefore, for most types of bearings that are simply bought; it should be more cost-effective than the repair; as long as the following conditions Next; think about the correction problem of the bearing; that is: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
.1) Many of the same types of bearings used in large-scale plants; the failure modes are mainly the wear of the tumbling surface; fatigue or fretting abrasion; especially the damaged parts are mostly cages or tumbling bodies; and the ferrule or gasket still has correction value,
.2) large and extra large bearings; close to failure or failure of the part without serious damage; or valuable bearings need to try to extend their useful period of use,
.3) Certain types of bearings that are difficult to purchase; have no spare parts after failure and have to be repaired; especially imported bearings,
.4) Bearings are subject to minor damage; such as subtle rust that occurs during the inventory period; and subtle fretting of the transport process; such corrections are abrupt and apologetic.
In addition to economics; bearing repair has its skill; this requires the repairer to fully understand the corresponding skill requirements of the bearing; and the layout, process and data characteristics of the bearing and its parts; otherwise it is difficult to ensure the repair of the bearing Have the effect of meeting the demand.
First, the economic benefits of bearing repair Generally speaking; the types of bearings are small; the number is large; the price of a single bearing is high; or the layout of the bearing is simple. The scale is large; the repair cost is relatively low; the higher the economic benefit.
Others; monitor the operation of the bearing; plan to repair the bearing before failure; can get twice the result with half the effort; follow a reasonable process; use efficient repair equipment and things; and get the assistance of professional bearing factory; Helps to improve economic efficiency.
Second, the advantages of cooperation with professional bearing companies users in the repair of the bearing business; if you can get the cooperation of professional bearing companies; will be able to get the following advantages:
.1) the skill requirements of each process that can be clearly repaired; and how to ensure the overall quality of the repaired bearings;
.2) Ability to use many of the specialized experience of specialized bearing plants; these experiences can reach process requirements reliably, efficiently, and economically.
.3) being able to order a mold for a professional bearing company; to repair the transaction; to be economical and save a lot of trouble,
.4) Ability to order from professional bearing companies such as cages; tumblers, Rivets and other accessories; can make the repair work simple and convenient.
