Seen on a shaft are respectively arranged at both ends of the two wheel roller bearing spherical roller bearing is 4 disc?? what is the harm?
but only a bearing hole boring, and the two bearing outer ring sizes (from micro perspective), to be installed in the same hole, it may produce inconsistent with the result, influence of bearing force.
Second, it is difficult to mount the 2 plate bearing on each bearing seat at the same time. The shaft down to say, but in fact in the manufacture of bearing outer ring deviation on (although within error),
Is generally not seen. First of all, the width of the two plate bearings increases a lot, which greatly reduces the angle or effect of allowing the adjustment of the heart. Can not play 4 sets of bearings, want to double the effect of heart adjustment.
