Single row tapered roller bearings, type 30204 bearings, shaft alignment, shoulder height?
3, the size of the cross section on the axis of the ladder is called the shoulder. According to its role, it can be divided into the locating shaft shoulder and the transition shaft shoulder.
1 、 the assembly height is 14.2, bearing (Bearing) is an important component of modern machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement and guarantee its rotation accuracy.
The shoulder of the positioning shaft is positioned; the transition shaft shoulder is provided for the disassembly of the parts on the shaft or the prevention of the stress concentration. But the axial shoulder will inevitably increase the diameter of the shaft, and the shoulder of the axle will change due to the stress concentration.
