Abstract
Device for centering and guiding a roller for supporting a massive component, incorporating, on each bearing face of the supporting components, two centering surfaces and at least one rack which are arranged in the direction of movement of the roller. The centering surfaces and the rack which are associated with one bearing face are placed opposite the centering components and the rack associated with the opposite bearing face. The roller incorporates the cylindrical roller wheels and at least one pinion in positions corresponding to the centering surfaces and the rack. The invention applies, in particular, to anti-earthquake bearing devices for a housing for storage of nuclear fuel assemblies.
