... arranged. Bearing selection The axial load of 130 kN is made up of the weight of the rotor and the two variable top and bottom fan im- pellers as well as the thrust of these fan impellers. They are ... pres- sure in the rolling contact area of the bearing is rela- tively low (p 0 ≤ 2,000 N/mm 2 ), and the bearings are failsafe. Consequently, the service life...

... 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 ... returns to the bearings. The labyrinth seal prevents the oil from escaping from the bearings and protects them from contamination. 19: Bearing arrangement o...
