Abstract

L'invention concerne un module à roulement à billes (80) servant à soutenir un moyen de traction d'un dispositif de convoyage le long d'un virage du dispositif de convoyage. Le module à roulement à billes comporte une multitude de rouleaux de soutien (130) servant à éliminer par roulement des forces liées au virage le long du virage du dispositif de convoyage. Les rouleaux de soutien (130) sont disposés de manière alignée les uns derrière les autres le long d'un corps de liaison (82). Le corps de liaison (82) est réalisé de manière flexible et déformable sensiblement de manière perpendiculaire par rapport à la rangée de sorte que l'agencement des rouleaux de soutien (130) le long du corps de liaison (82) peut être adapté conjointement avec le corps de liaison (82) de manière flexible aux tracés de virage présentant des rayons de virage différents.
