Generally speaking, a shaft need two stand, and each pivot may consist of one or more than one of the bearing is composed. Novice replacement roller skating bearings with existence of the error analysis of the bearing should be considered reasonable allocation in the machine have the correct axis, the position of prevent axial channeling move and axle expands not will bearing card to die after, and other factors.

The commonly used method has the following three bearing configuration of:

Double protection one-way fixed

Installation and replacement of the bearing configuration bearing technology commonly used two reverse installation Angle contact ball bearing or tapered roller bearings, two bearing the limit a direction of the axial movement. Installation, adjustment bearing outer ring or through inner circle of axial position, can make to achieve an ideal bearing clearance or the required preloaded degree. Structure are supporting small cantilever bevel gears shaft. Can be seen from the graph, in supporting the same condition of distance b, the distance between the pressure center, and L1 < L2, so the former cantilever longer, supporting the rigid is poorer. In the heated deformation of precision bearings between process new technology for running rust analytical when the temperature of the shaft generally higher than the shell temperature, the axis of the axial and radial thermal expansion will be greater than the thermal expansion of shell, then figure 1 structure reduced the preset clearance, may cause card to death, and the figure 2 structure can avoid this kind of circumstance happening.

Reasonable import bearing configuration should consider shaft in the machine have the right position
