▎ 摘　　要

NOVELTY - Low-deformation roller bearing comprises bearing outer ring (1), bearing inner ring, and roller. The roller is rotatably connected to bearing inner ring. It further comprises rear baffle (4) and front baffle. The rear baffle and the front baffle are passed through rivets (6) fixed on bearing inner ring. An annular groove is opened on annular wall of bearing outer ring close to bearing inner ring. First heat dissipation hole grooves (8) are opened on outer end surface of bearing. Graphene filler (9) is filled and fixed in annular groove and first heat dissipation hole groove. Lubrication pits opened on ring wall of bearing outer ring close to bearing inner ring. A lubrication hole is opened in bearing outer ring and communicates with lubrication pit. A lubricating paste is filled in lubricating groove. USE - The bearing is used for low-deformation roller. ADVANTAGE - The bearing has good radiating ability, and good deformation resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of lubricating paste. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of low-deformation roller bearing.
