Abstract
A roller assembly for a screening device includes a shaft extending along a width direction, a pair of discs disposed on the shaft, and a spacing assembly disposed on the shaft between the pair of discs. The spacing assembly includes an inner spacer disposed around the shaft and an outer spacer disposed around the inner spacer. The outer spacer has a body defining an inner receiving space and a support element disposed in the inner receiving space. The body abuts against the discs and is formed of an elastically compressible material. The support element limits compression of the body along the width direction.
