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:
(1) Many of the same types of bearings used in large factories; 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 ferrules or gaskets still have corrections. value,
(2) large and extra large bearings; close to failure or failure, but the parts have not been seriously damaged; or valuable bearings need to try to extend their useful period of use,
(3) Some types of bearings that are difficult to purchase; there is no spare parts after failure and have to be repaired; especially imported bearings,
(4) The bearing has minor damage; for example, the fine rust that occurs during the inventory period; and the slight fretting abrasion that occurs during the transportation process; it is a pity that such condition correction is abbreviated.
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 quantity 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:
The user is in the process of repairing the bearing; if you can get the cooperation of the professional bearing company; you will 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) It is possible to order a mold for a professional bearing company; it can be used for repairing affairs; it can be economical and saves a lot of troubles.
(4) Can order from professional bearing companies such as cages; tumbling bodies, rivets and other accessories; can make the repairing work simple and convenient.

Nylon Standoffs are made of nylon material. The standard shape is round nylon standoffs and hex nylon standoffs. Hex nylon standoffs are more popular. Black color is more common, but white color is also ok if you need. We have many kinds of sizes in stock. Thus once required,we could ship them out soon. Both male to female nylon standoffs and female to female nylon standoffs could be offered. They are ideal for mounting between PCB circuit boards and mane boards. Sure,for assembly, nylon Screws and Nylon Nuts are available.
