As we all know, screw conveyor is a conveying equipment which transport material under the help of screw blade rotation. If the conveyor length is too long, the screw shaft will collapse, so we need to install the intermediate bearings to avoid the excessive abrasion due to the shaft collapse, besides, that’s why the hanger bearing is the most easily wear part.

The spiral conveyor service life depends on the hanger bearing service life, after hanger bearing break, the screw conveyor will not work.
The intermediate bearing is made of abrasion-resistant alloy, we need to add the lubricating oil before conveyor working so as to prevent the excessive friction causing a huge abrasion to the hanger bearing, as well as unnecessary losses.

Besides, normal working of intermediate bearing can ensure the coaxiality of screw conveyor feeder, resistance and noise of the screw conveyor,etc., at same time in a good working condition with a better using effect and longer service life.
