However, all things are divided into two, and bearing also has certain shortcomings, mainly:

1. Bear the load bearing capacity than the same volume of plain bearings is much smaller, therefore, the radial bearing large size. So, under heavy load situations and requirements of the radial, small size, compact structure, the occasion requires "such as crankshaft bearings), the use of sliding bearings;

2. Large rolling bearing vibration and noise, especially late particularly significant in the use, therefore, requires high precision, without Xu Youzhen moving occasion, bearing hard competent, generally used in sliding bearings better

3. Rolling of metal shavings and other foreign bodies are particularly sensitive to foreign matter enters the bearing, it will have a larger vibration and noise intermittently, also cause early damage. In addition, the bearing impurities due to metal clips, also prone to the possibility of early damage. Even if early damage does not occur, the life of rolling bearings there are certain limits. In short, the life of rolling bearings shorter than the sliding bearing.

However, compared to rolling and sliding bearings, each with advantages and disadvantages for the possession of certain situations, so the two can not completely replace each other, and each to a certain direction, to expand their fields. However, due to the outstanding merits of rolling bearings, rather then those living on the trend. Currently, the rolling machine has developed into a major bearing type, application of more extensive

The rolling bearing type, structure type, tolerance level, technical requirements, such as different materials and quantities, the basic production process is not the same.
First, all bearing the main part of the process:
1. The processing of rings: bearing inner and outer rings of the processing according to the form of raw materials or rough vary, including car before processing can be divided into the following three processes, the whole process as follows: bar or tube material (subject to some bar forging and annealing, normalizing heat treatment )---- vehicle processing ---- ---- ---- grinding, lapping or polishing the final part inspection ---- ---- Rust ---- ----( be combined storage sleeve>
2. The processing of steel ball, steel ball processing the same according to the state of raw materials vary, which frustrated the ball before cutting or optical processes can be divided into the following three, before heat treatment processes, can be divided into the following two, the whole process is: cold punch bar or wire (some bar needs to punch after punch cold and annealing )---- setback zone cut, coarse, soft grinding or ball of light ---- Heat Treatment - hard-grinding mill ---- --- ---- ---- lapping or grinding group ---- rust final inspection, packaging, warehousing ---- <to be co-sleeve>.
3. Process roller roller processing of raw materials vary according to different, pre-heat treatment process can be divided into the following two, the whole process as follows: bar car, after processing or cold heading wire string band and Polishing Heat ---- ---- ---- coarse string soft spot diameter coarse face ---- ---- ---- end of fine grinding diameter end mill end mill diameter ---- ---- Group ---- rust final inspection, packaging, warehousing ---- (to be co-sleeve>.
4. The processing of the cage cage design process according to the different structures and materials can be divided into the following categories:
(1) → cutting → blanking sheet metal forming → → → shaping and finishing pickling or shot blasting or string light → → rust final inspection, packaging → storage (to be co-sleeve)
(2) the processing of solid cage: solid cage of processing, raw materials or by bad hair varies, of which cars can be divided into the following four pre-processing rough style, the whole process are: bar, tubing, forgings, castings ---- Car diameter, diameter, face, chamfer ---- drilling (or broaching, boring, pickling )---- ---- ---- Final Inspection rust, packaging, warehousing ---- <to be co-sleeve>.

Second, the bearing assembly process:
Bearing parts such as inner, outer ring, rolling body and cage, etc., have passed the test, go to the assembly plant for assembly, the process is as follows:
Part demagnetization, cleaning → inside and outside roll <ditch> Road size group together sets of sorting → → → check clearance riveting cage → → demagnetization final inspection, cleaning → rust, packaging → into finished products (packing, shipping >.
