Although many types of rolling bearing, structure type and tolerance grade differences, material selection, processing method, but the basic manufacturing process includes the following contents:


Bearing parts manufacturing - bearing parts inspection part bearing demagnetization, cleaning, rust, bearing assembly bearing product inspection, bearing demagnetization of finished products and cleaning bearing product packaging tubing to arrange the warehouse.


An important part of the rolling bearing ring, due to all kinds of rolling bearing, the different types of bearing ring size, structure, production equipment, process method, etc. Each are not identical. The ring machining process, the process is more complex, high machining accuracy, therefore, the precision bearing ring processing quality, has a great influence on service life and performance.


Ring by the raw material of cylindrical bar stock or tube material, according to the forming process, the rolling bearing ring usually has the following several kinds of manufacturing process.


1) and (bar) material, forging, annealing (or normalization, the cold bending) (- heat treatment quenching and tempering, grinding - check - demagnetization, clean - submit assembly parts


2), (bars, tubing blanking, forming, quenching and tempering heat treatment of cold rolling mill - check - demagnetization, clean - submit assembly parts


3) and (tube) electric mill cutting cutting molding - heat treatment quenching and back - check - demagnetization, clean - submit assembly parts


4) and (bar) material cold (warm) extrusion - will be heat treatment quenching and tempering, grinding - check - demagnetization, clean - submit assembly parts


Ring forming method


In the ring processing, molding method basically has the following kinds: forging forming, cutting, forming, cold rolling and cold extrusion molding (temperature). Formed in the above molding methods, the most widely used, which accounts for about 80% of the total output, for a few small gm products can use bar (tube), direct cutting shape. Since the 1980 s, some of China's small and medium-sized enterprises to adopt the production of small and medium sized ring, cold rolling and cold extrusion molding process (temperature).


1), forging forming Purchase For SKF Bearings http://www.pillow-block-bearings.net/index.htm .



By forging processing, metal internal defects may eliminate to improve the organization of the metal, the metal flow distribution is reasonable, the metal seal. Forging forming technology is widely used in bearing processing, can do ~ 20 mm diameter small diameter 5000 mm oversize material handling products. Normal forging forming method: hot forging, cold forging, machining and hot forging processing, mainly in hot forging in our country.


Hot forging processing because of its different forming equipment is divided into: free forging process and forging process and forging machine forging process and the upsetting process.


2), cold rolling forming


Cold ring rolling technology is a kind of can improve material utilization, improve the metal tightly, keep the metal flow linear method of advanced technology, is a kind of chipless machining method. Theoretically, cold bending forming products can not directly in the heat treatment and grinding. At present, the cold rolling technology is mainly used for medium and small deep groove ball bearing, the main process:
