# Bearing chain assembly

## Abstract

A bearing chain assembly may include vertical load bearings each having a first rotation axis and configured to roll along horizontal support structure of a drive system while supporting vertical loads of a spiral conveyor belt; radial load bearings alternately coupled with the vertical load bearings and each including: a roller assembly configured to facilitate rolling of the bearing chain assembly along vertical support structure of the drive system while supporting radial loads of the spiral conveyor belt and/or the drive system. The roller assembly includes first and second roller wheels each having a rotation axis substantially perpendicular to the first rotation axis and made of a first material; a first glide bearing secured to the first roller wheel, the first glide bearing made of a second material having a lower frictional resistance than the first material; and a connection assembly for coupling the first wheel to the second wheel.
