Bearing Housings Series

According to its structure, the bearing housings can be divided into split bearing housings, integral bearing housings, flange bearing housings, outer spherical bearing housings, etc. Rolling mills are mainly used in integral bearing housings. The main materials for manufacturing bearing housings are cast steel (such as ZG45), gray cast iron (such as HT200), ductile iron (such as QT400-17) or stainless steel. The rolling mill bearing housing is mainly made of cast steel. The choice of bearing housing blank is related to its material, structure and size. Bearing holes with smaller diameters are generally cast in steel molds, and solid castings can also be used; sand molds are used for larger diameters; steel molds are generally used in mass production, which can improve productivity and save materials.
