Spiral bearing system adopts the steel belt winding screw roller.So called spiral roller bearing.This kind of bearing has great flexibility and radial clearance, able to withstand the impact of the big radial direction load, unable to bear axial load, limit rotational speed is low.Is only applicable to rotating accuracy is not high, and often have a larger impact load components.Axis bearing installation allows the axis of the inner ring and outer ring is 0.5 ° inclined.Due to the elastic deformation of the bearing, in the work can not guarantee the accuracy, so the precision of spiral roller bearings only regular grade a, there is no other precision level.
