... accuracy of the workpiece mainly depend
on the axial rigidity of the spindle headstock and of the
rotary table. Therefore, the rigidity of the thrust bear-
ings is especially important. To increase the ... conditions as the expansion of the rotating parts

... clearance
Due to the tight fits, the inner ring of the bearing is
expanded and the outer ring with the roller-and-cage
assembly is contracted. Thus the radial clearance of the
bearing is reduced ... V1.
Bearing selection
The selection of the bearings is primarily based on the
main thrust, which is directed downwards. It is made
up of the weight of the rotor...
