NOVELTY - A composite material supporting roller structure comprises tube component (1) set with sealing component connected with bearing seat and containing shaft tube and shaft base (3), and has graphene PTFE modified friction material. The outside of inner side surface of the sealing cover (5) and sealing base (4) is matched with gap, and forming sealing space. The sealing space assembly has separate sealing ring (6), and the sealing space and separate sealing ring formed into maze sealing structure. USE - Composite material supporting roller structure. ADVANTAGE - The structure has practical value, increases sealing property, and does not enlarges resistance. DETAILED DESCRIPTION - A composite material supporting roller structure comprises tube component (1) set with sealing component connected with bearing seat and containing shaft tube and shaft base (3), and has graphene PTFE modified friction material. The tube component comprises tube, sealing component and shaft. The internal tube is set with supporting ring. The sealing component comprises tightly matched sealing base and bearing base. The outside of inner side surface of the sealing cover (5) and sealing base (4) is matched with gap, and forming sealing space. The sealing space assembly has separate sealing ring (6), and the sealing space and separate sealing ring formed into maze sealing structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of composite material supporting roller structure.
