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.

 
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, high carbon chromium bearing steel


The vast majority of Bearing skf http://mwovu.fkq199.com/ ring and rolling body is made of special steel. With high carbon chromium bearing steel (GCr15 and GCr15SiMn and 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 Bearings SKF http://aqkwa.fkq199.com/ generally applicable to the working temperature range for - 40 ~ 130 degrees, oil and grease lubrication is normal. Can meet the requirements of general machinery.


High carbon chromium bearing steel Bearings skf http://votga.fkq199.com/ 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, general fitness and to work for - 40 ~ 140 degrees Celsius temperature, 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, heat-resistant bearing steel


Made of heat resistant Bearing SKF http://ryflu.fkq199.com/ steel 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, corrosion resistant bearing steel


Made of corrosion resistant bearing steel 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 is - 253 ~ 350 degrees Celsius.
