The choice of bearing material

<p><span style="color: rgb(136, 136, 136);">The selection of bearing substance is designed according to the operational requirement of the functioning condition of posture and bearing parts.&nbsp;The rolling bearing is mainly composed of the ring, rolling body, cage along with other components, the substance of the part can be divided into ( 1) Ring and roller materials; ( two ) Cage materials; ( 3) Other parts like a rivet, dust cap, seal, etc..&nbsp;The aforementioned parts, variety of substances, because of their physical and chemical and mechanical properties of different, and each has different attributes, to accommodate to the work under different working conditions and ecological conditions.&nbsp;<a href="https://www.wxingbearing.com/" target="_blank">Bearing material</a> choose appropriate or not directly related to if meeting the function and use requirement of institutions, on bearing performance and fatigue life has a decisive influence.&nbsp;Usually, under the state of material to choose the right, as long as cooperating with normal installation, lubrication, and maintenance, the bearing will achieve good working performance and reliability requirements.&nbsp;Here briefly explain the bearing ring, rolling body, and keep back the substance application.&nbsp;1.&nbsp;Ring and roller substances ( 1) Most of the carbon chromium bearing steel bearing ring and rolling body is made of special steel.&nbsp;&nbsp;Made from high carbon chromium bearing steel posture generally applicable to the working temperature for - Range of 40 ~ 130 levels, oil, and grease lubrication is normal.&nbsp;Can satisfy the demands of general machinery.&nbsp;High carbon chromium bearing steel bearing components after high temperatures in the fire, it adapts to the working temperature can be as large as 250 degrees.&nbsp;Together with the progress of the smelting technologies, the high carbon chromium bearing steel smelting can embrace different methods, such as vacuum smelting technology may produce the reform of the immanent quality of steel, the standard is that the oxygen content in steel, as well as the formation of the non-metallic inclusions, has decreased significantly.&nbsp;Made of this kind of high carbon chromium bearing steel bearing, its fatigue life may be growing exponentially.&nbsp;According to a large number of trials comparing statistics reveal that distinct smelting method for GCr15, GCr15SiMn, ZGCr15, ZGCr15SiMn bearing steel bearing.&nbsp;( 2) Carburizing bearing steel manufactured from carburizing bearing steel ring and rolling body, its hardness is: race and rolling components are HRc60 ~ 64, the overall optimal temperature for - and at work 40 ~ 140 degrees Celsius, oil and grease lubrication is ordinary, can be used in larger impact vibration problems, such as locomotive and rolling mill posture, etc, but the steel heat treatment procedure is more complex.&nbsp;&nbsp;( 4) Corrosion-resistant bearing steel with rust-resistant bearing steel fabrication ring and rolling body, its hardness is: race and rolling components should not be lower than HRc58, suitable for its corrosive medium like water, nitric acid, chemical reagents, the temperature was minus From 253 to 350 degrees Celsius.&nbsp;2.&nbsp;Cage materials ( 1) Most bearing adopts steel cage, the most frequently used is low carbon steel plate stamping ribbon, basket, box, such as a cage, is acceptable for the usage of high carbon chromium bearing steel bearing conditions and the environment; In carbon stainless steel steel plate stamping with cage is suitable for the corrosion resistance of the bearing steel bearing conditions and the surroundings.&nbsp;( 2) With exceptional non-ferrous metal smooth surface quality.&nbsp;Work under high-temperature conditions may use silicon bronze manufacture solid cage, working temperature can reach 315 degrees Celsius; Because of the strength of the aluminum is lower than brass, the proportion of lighting, and therefore commonly used aluminum and brass cage manufacturing entity, mainly is suitable for the higher speed, weight is lighter, rust resistance and other ailments.&nbsp;( 3) Made of engineering plastic cage, also has a great development in recent decades, mainly since it has particular corrosion resistance, good self-lubricating performance, small friction resistance, use convenient, price cheap, easy in manufacturing, but easy to say'aging'.&nbsp;Currently, the most frequently used of reinforced nylon 66 was utilized in a temperature range for - it can continue to operate 40 ~ 120 degrees Celsius.&nbsp;Teflon high durability, lubricating, the constant working temperature may reach 300 degrees Celsius, phenolic glue has high mechanical strength, fantastic abrasion resistance heat resistance, but that is expensive, suitable for high speed spinning around, working temperature for - 40 ~ 150 degrees Celsius, instantaneous can be as high as 180 degrees Celsius.</span></p><p><br></p><p><span style="color: rgb(136, 136, 136);">&nbsp;Retainer?&nbsp;On either side of the side together with the ring and rolling body, or its side sliding touch, 1 side under tension and compression force.&nbsp;For the above-mentioned reasons, the bearing ring, rolling body substances, performance, and so on has the following basic conditions: 1, large 2 rolling fatigue strength, high hardness, Higher resistance to friction consumption 4, 3-dimensional stability good 5, mechanical power, large bearing cage performance demands: 1, high resistance to friction consumption two, good dimensional stability and mechanical strength</span></p><p><br></p><p>&nbsp;</p>
