The intermediate bearing is divided into three rod type (SL type), three channel steel three-axis type (SC type), well-word channel type (JC type), three-bar type hanging type (SD type) and the like. The intermediate bearing mainly bears the radial load generated by the self-weight of the shaft, the deformation and the rotation of the shaft. The intermediate bearing is divided into two types: sliding bearing and rolling bearing according to its basic structure and friction form with the shaft contact part.
