Selection of deep groove ball bearing rings and roll body raw materials
Clicks:36353 Date:1-10
Deep groove ball bearing is a common form of our daily life. Deep groove ball bearing is mainly composed of outer ring, inner ring, tumbling body and cage. About deep groove ball bearing raceway and rolling body, a very important raw material selection, the two parts can be deep groove ball resolution bearing function application, we can according to the need to select deep groove ball bearing fit rings and rolling body material.
1. High carbon chromium bearing steel
The vast majority of bearing rings and roll bodies are made with special steel. A high carbon chromium bearing steel (GCr15 and GCr15SiMn and ZGCr15 and ZGCr15SiMn) is used to make a ring and roll body. The hardness of the part is as follows:
The rings and rollers made with GCr15 and ZGCr15 data are HRc61~65, and the steel ball is HRc62~66.
The rings and rollers made with GCr15SiMn and ZGCr15SiMn data are HRc60~64, and the steel ball is HRc60~66.
The bearings made of high carbon steel chromium bearing steel are usually applied to the scale of working temperature of -40~130 degrees, and the oil and grease are smooth and normal. It is satisfied with the usual mechanical request.
High carbon chromium bearing steel bearing parts can be used as high as 250 degrees at high temperature after high temperature return.
2, carburized bearing steel
By making the carburizing bearing steel rings and rolling bodies, the hardness of roll body and ring: HRc60~64, usually suitable to the working temperature is -40~140 degrees Celsius scale, oil and fat smooth normal, can be used in large impact oscillation conditions, such as bearings for locomotive and rolling machine, but the heat treatment technology the steel complex.
3. Heat resistant bearing steel
The rollers made of heat-resistant bearing steel have their hardness: rings and rollers HRc60~64, and steel balls HRc61~65. Under normal and smooth conditions, they are suitable for working conditions of 120~250 degrees Celsius, such as aero engines and gas turbines.
4. Corrosion resistant bearing steel
The corrosion resistance bearing steel is used to make rings and tumbling bodies. The hardness is: the rings and rollover bodies should not be lower than HRc58, and are suitable for corrosive media such as water, nitric acid and chemical reagents. The temperature is -253~350 Celsius.
