By when we test bearing flexibility, is a clumsy method of comparison used, we find some information on the Internet today, and we can look at some simple testing method of bearing, so that we daily use.
Bearing rotation of long duration, bearing when the rotation is of long duration, stop slow, flexibility would be great. In contrast, rotation time is short, stop suddenly, flexibility is bad, from the radial internal clearance of the bearing to the new, to measuring the radial internal clearance of the bearing will not be easy, because the measure will cause bearing rings and rolling elements and elastic deformation of contact in itself.
From the structure and size of the bearing ways because of different bearing type and size, rotate it flexibility should also have different requirements. Such as separate radial ball bearing, and separate radial thrust ball bearing, due to scroll body and rings Zhijian of contact area small, these bearing rotating Shi on comparison light, and double column radial spherical bearing and thrust roll child bearing, due to scroll body and roll road of contact area larger, patrons ring of weight and smaller, in check its rotating flexibility Shi, although plus must load, but its light degree still than separate radial ball bearing.
