For reference, the Aciera F4 and F5 use opposing tapered roller bearings at the rear of the spindle to handle both radial and thrust loads. Their axial clearance setting when cold is 5 µm (0.0002"). The nose bearing, which is a two-row cylindrical roller bearing with tapered bore, only handles radial loads.
The drive of a vertical roller mill – essentially the mill gearbox – has to fulfill two tasks: The first is to reduce the speed of the electric motor to the selected mill speed and to transmit the torque created by the motor. Secondly, the gearbox has to transmit the grinding forces generated by the grinding rollers, from the mill table ...
