Imported bearing manufacturing

Imported bearing manufacturing NMB bearing manufacturing bearing life and reliability is implemented and give full play to the important means of design potential. In the manufacture of bearing parts, the product had a greater influence on the performance of the parts are rolling body and the ring, as a result, ring and rolling system technology directly affects the bearing can be used on sex and life. Import seiko bearing manufacturing materials selection, the following study together the imported bearing manufacturing. A bearing manufacturing process (basic Spherical roller bearing, for example) 1, ring ( Inner ring and outer ring) Materials forging processing turning processing grinding heat treatment processing and assembling, rolling body (2 Roller) Grinding processing and assembling is turning processing heat treatment 3, cage ( Copper frame) Material casting ( Tubular) Turning milling deburring assembly two ring and rolling element bearing manufacturing materials commonly used materials: high carbon chromium bearing steel Gcr15Gcr15SiMn other materials: carburizing bearing steel, corrosion resistance of bearing steel, heat-resistant steel bearing cage materials: non-ferrous metals: brass HPb59 - 1 bronze QAL10 - 3 - 1. 5 aluminum alloy LY11CZ black metal: quality carbon steel thin plate non-metallic: engineering nylon phenolic adhesive is bearing ring forging processing forging process processing of pretreating, also known as blank processing. The main purpose of ring forging process is: 1. Similar to the product shape of blank, so as to improve the utilization rate of metal material saving raw materials, reduce the mechanical processing capacity, reduce the cost. 2. Remove metal internal defects, improve the metal organization, make metal flow distribution is reasonable, good tightness, metal so as to improve the service life of bearing. 3. 1, hot forging forging processing - — 2 is widely used in metal is heated to above the recrystallization temperature, cold forging - — Metal at room temperature, warm forging deformation rarely use 3 - — Between hot forging and cold forging metal deformation test phase
