(1) Sheet → shear → punching → stamping forming → shaping and finishing → pickling or shot peening or stringing → final inspection → rust prevention, packaging → storage (to be combined)
(2) KOYO bearing entity adheres to the processing process of the frame: The processing of the entity insists on the frame, which varies according to the original data or the hair damage. Before the car processing, it can be divided into the following four blank types, the whole process For: Bar, pipe, forgings, castings----car inner diameter, outer diameter, end face, chamfering----drilling (or pulling holes, boring)----pickling----finish Inspection----Anti-rust, packaging----into the warehouse <to be combined with the device>.
Second, the maximum use of KOYO bearings in the life of the bearing life in addition to the quality of the product itself; there are some important elements.
First, during the selection of bearings; need to consider many factors (such as: load; hardness; operating environment, etc.); good bearing depiction will first cause the bearing to reach its maximum life value.
Second, the correct storage; bearings should be kept in their original packaging before the device. The need to stay in a hygienic, moisture-free, relatively constant temperature environment. Rolling bearings should be away from dust, water and corrosive chemicals. Swing And sensation may permanently damage the mechanical properties of the bearing; therefore, sensation should be avoided during handling and storage.
Usually the bearings should be stored horizontally; some of the heavier bearings are placed vertically after being placed vertically; they will be deformed by their own weight!
Also; greased (or sealed) bearings need to be uniquely guarded; density will change as the grease is stored for long periods of time. When the bearing is first used; there will be a certain degree of conversion noise. Therefore; Placement should be controlled according to the first-in, first-out criteria!
Third, hygiene; this is very important for rolling bearings. The transition surface of the bearing ring is very smooth; the damage caused by the formation of pollutants is very sensitive. The particulate impurities will be over-rolled by the rolling elements and some pressure will occur in the bearing; Permanent information is exhausted.
Fourth, all equipped with re-equipment; bearings should be carefully installed and disassembled with appropriate things (can refer to the bearing unpacking series video). Should choose the right thing! Professional professors estimate; bearings fail prematurely; 16% are due to incorrect devices. Usually many devices are used; usually suitable bearing devices are adopted.
But in the protection or exchange work; the environment is diverse! Advocate us; relevant drawings; protection manual; product manuals need to be carefully looked at. Bearing components should also adhere to affirmative hygiene!
5. Careful installation and disassembly; the bearing device has been talked about repeatedly in the past (we have similar problems; there are some articles on bearing devices); once again, briefly summarize:
1. Do not apply device force on the tumble element; this is very simple to cause partial overload of the tumble element and the touch surface of the race; then the premature failure of the guide bearing.
2, do not use any hard things (such as hammers; screwdrivers; etc.; I have seen too many "hard" devices with these two things; too strong) directly knock on the bearing appearance; this will lead to cracking or breaking of the bearing ring.
3, usually the bearing will not be removed from the equipment; as long as the larger bearing will be removed due to preventive protection. Unpacking process; the first thing should be the correct thing; to ensure that the adjacent parts are not damaged!
Sixth, correct and appropriate smoothness; smoothing agent can block the bearing appearance; then reduce the conflict; protect metal parts and avoid pollution and impurities. There are a variety of smooth grease for different operating conditions.
Due to excessive tumbling of the tumbling parts; the bearing smoothing agent is subjected to long-lasting mechanical stress; and especially in high temperature, wet or contaminated environments for long periods of time; the chemical properties of the smoothing agent may be modified. These will result in smooth quality In addition to; so; to re-smooth the bearing at regular intervals. Cycle by operating conditions.

Thimbles
Thimbles is design for protect wire rope , help to bending the rope to easy lift the goods . our standard size is DIN 6899A and DIN 6899B . we also produce the us type and other country standard size .The most common surface treatments are Cr+6 free zinc, zinc nickel alloy, electroless nickel plating or customer specified types, theses plating can stand salt spray anti rust testing.
