2016-08-30

The screw conveyor bearing can be divided into three types:head bearing,tail bearing and middle bearing.
The head bearing is thrust bearing,which is adopted conical roller bearing and can bear the axial force from the material transportation.This bearing is installed at the head part,the shaft only bearing tension,and this tension is favorable.
The tail bearing is transverse bearing, it is adopted double row centripetal spherical bearing or sliding bearing,except the function of rotary,it also needs self aligning.
Middle hanger bearing can be used when the screw conveyor is longer than 3-4m,its main effect is to bear the shaft weight and rotary force.
