Jiaxing bearing on the working temperature of rolling bearings

There is rotational, have HRB bearing ( ) 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 according to their material selection and heat treatment process and the use of lubrication conditions at work, in product design phase and production processing manufacturing process its working temperature is given. Details are as follows: a. Material selection 1. General bearing under normal operating temperature ( Room temperature) Can be according to the national standard GB/T18254 - 2002 the high carbon chromium bearing steel material. 2. High temperature bearing operating temperature over 300 ℃ above are in accordance with the YB688 - 2000 the condition of high temperature bearing steel Cr4MO4V technology selection. 3. Low temperature bearing ( Working temperature below - Bearing under 60 ℃) , commonly used 9 cr18 stainless bearing steel, 9 cr18mo materials, can be in accordance with the GB/T3086 - 1982 'high carbon chromium stainless bearing steel technical conditions, material selection, also can choose beryllium bronze, ceramics and other materials. two Heat treatment process 1. General bearing when choosing high carbon chromium bearing steel, the heat treatment process according to the national machinery industry standard JB/T1255 - 2001 'high carbon chromium bearing steel rolling bearing parts heat treatment technical conditions'. 2. When working temperature higher than 300 ℃ high temperature bearing according to JB/T2850 - 1993 'Cr4MO4V conditions of high temperature bearing steel rolling bearing parts heat treatment technology, to be applied. 3. According to JB/T1460 - low temperature bearing 2002 'high carbon chromium stainless bearing parts heat treatment technical conditions of processing, to be applied. 3. 1 rolling bearing working temperature. General bearings use high carbon chromium bearing steel and heat treatment process according to the above processing after rolling bearing under normal working state, Room temperature) Working temperature in accordance with the relevant standards, that is, through the life and reliability test and evaluation after, can be controlled by this. 一个。 See JB/T50013 - test regulations 2000 the rolling bearing life and reliability test procedures, article 5 test conditions, 5. 4: when temperature grease lubrication bearing outer ring, don't allow more than 80 ℃; Oil lubrication, are not allowed to exceed 95 ℃. b。 See GB/T24607 - test and evaluation 2009 'rolling bearing life and reliability test and evaluation of' national standard test conditions in accordance with article 6, 6. Item 2: when circulating oil lubrication, the bearing outer ring temperature generally should not exceed 95 ℃; Grease lubrication, the bearing's outer ring temperature generally should not exceed 80 ℃. 2. Under the condition of high temperature bearing working temperature: a. Choose high carbon chromium bearing steel rolling bearing, working temperature between 150 ℃ ~ 350 ℃, according to standard JB/T2974, when working temperature between 150 ℃ ~ 350 ℃, the suffix in bearing type can be tagged S0 ~ S4 said. b。 Rolling bearing using high temperature bearing steel, its working temperature is 300 ℃ above, specific work temperature according to the working conditions shall be given separately. 3. Low temperature bearing working temperature: rolling bearings use high carbon chromium stainless bearing steel, its working temperature below 60 ℃ below zero, specific work temperature according to the working conditions shall be given separately.
