Introduction often used in screening machine eccentric shaft

        Screening machine used in bearings, after years of practice, that the choice of three groups and four groups clearance more appropriate, that a large clearance bearings.

Clearance in each group, the size of the radial clearance values, according to the bearing diameter varies. Commonly used stone screening machine bearing diameter, usually in

d6s ~ 4180mm range greater. Bearing running clearance, the bearing radial clearance than small. It is subject to the assembly line with the nature and the operating temperature,

etc. due to the impact of cable.

        The so-called mill running clearance, after the bearing assembly is, in operation, the bearing ring and the gap between the rollers. Running clearance should generally

be greater than o. Screening machine vibrator working state, determines the load bearing states. As commonly shaker rotating eccentric block or partial

Mandrel as excitation source, so the bearing outer ring subjected to cyclic loading, a fixed load bearing inner ring. Meanwhile, the dryer manufacturer that due to their higher

operating temperature, thermal expansion to compensate for parts, shrink. Thus, dewatering screen  bearings with a one certain characteristics.
   
      Broken stone gravel production line in some countries, in order to prevent the bearing outer ring and housing between the sliding interference fit. Such as pore size less

than 15 0mm, using N6; against big aperture 150mm, using P6. The inner ring of the bearing and the journal with, a loose fit

. Such as the journal is less than 80mm, the use of g6, big 80mm for the journal, the use f6.
