Bearing apparatus has supply hole extended in tangent direction with respect to cyclic path for supplying lubricant and excretory pore following radial direction outer side of cyclic path for ejecting contamination particles

摘要

The bearing apparatus has a supply hole (14) extended in a tangent direction with respect to a cyclic path (12) and by which a nozzle (16) is integrally formed for supplying lubricant to the cyclic path with a turning component. An excretory pore (18) follows a radial direction outer side of the cyclic path for ejecting contamination particles centrifuged from the lubricant from the cyclic path.
