Listen to jiaxing bearing small make up to introduce material selection of rolling bearing ring and rolling element

There is rotational, have HRB bearing ( ) For material selection of rolling bearing ring and rolling element, we invite our jiaxing bearing engineer today for everyone to do a detailed introduction and guidance, hope everyone can learn. Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Rolling bearing is one of the daily life, we use type, the rolling bearing is mainly composed of outer ring, inner ring, rolling body and keep the frame combination. For rolling bearing rings and rolling body, when the choice of material is very important, the two parts can decide the performance of the rolling bearing is used, we can undertake choosing according to requirements in accordance with the material of rolling bearing ring and rolling body. 1, the vast majority of high carbon chromium bearing steel bearing ring and rolling body is made of special steel. With the high carbon chromium bearing steel ( GCr15 and GCr15SiMn ZGCr15 and ZGCr15SiMn) Make ring and rolling body, its parts hardness is as follows: made of GCr15 and ZGCr15 material ring and roller for HRc61 ~ 65, steel ball is HRc62 ~ 66; Made of GCr15SiMn and ZGCr15SiMn material ring and roller is HRc60 ~ 64, steel ball is HRc60 ~ 66. Made of high carbon chromium bearing steel bearing generally applicable to the working temperature for - Range of 40 ~ 130 degrees, oil and grease lubrication is normal. Can meet the requirements of general machinery. High carbon chromium bearing steel bearing parts after high temperature in fire, it adapt to the working temperature can be as high as 250 degrees. 2, carburizing bearing steel made of carburizing bearing steel ring and rolling body, its hardness is: race and rolling elements is HRc60 ~ 64, the general optimum temperature for - and at work 40 ~ 140 degrees Celsius, oil and grease lubrication is normal, can be used in larger impact vibration conditions, such as locomotive and rolling mill bearing etc, but the steel heat treatment process is more complex. 3 steel made of heat resistant bearing steel bearing ring rolling body, its hardness: ring and roller is HRc60 ~ 64, steel ball is HRc61 ~ 65, in the case of normal lubrication, is suitable for the working temperature is 120 ~ 250 degrees Celsius, such as aviation engine, gas turbine spindle working conditions. 4, and corrosion resistant bearing steel with corrosion resistant bearing steel manufacture ring and rolling body, its hardness is: race and rolling elements should not be lower than HRc58, suitable for the corrosive medium such as water, nitric acid, chemical reagents, the temperature of - From 253 to 350 degrees Celsius.
