Bearing with lubricating means

摘要

A bearing apparatus includes: two split outer ring halves (3a,3b) which includes outer ring raceway surfaces and are disposed within a supporting hole (13) of the housing, respectively; and a plurality of rollers which are disposed on respective inner surfaces of the both split outer ring halves and supports a shaft. Each of the two split outer ring halves includes an oil hole (8a,8b) penetrating the split outer ring half in a radial direction thereof and an oil groove (9) formed on an outer diameter surface of the split outer ring half along a circumferential direction thereof to allow the oiling passage and the oil holes to communicate with each other. Each of the oil holes is disposed at a position located at an angle of within 45° from the joint surface of the split outer ring halves in an opposite direction to a rotating direction of the shaft.
