THRUST ROLLER BEARING FOR CAR AIR-CONDITIONER COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a thrust roller bearing for a car air-conditioner compressor, having improved exfoliation resistant life by reducing differential slippage and edge load under severe lubricating oil circumstances where lubricating oil is mixed into hydrochlorofluorocarbon base refrigerant.

SOLUTION: The thrust roller bearing for the car air-conditioner compressor is incorporated in a cooling-cycle compressor of a car air-conditioner in which lubricating oil mixed refrigerant formed by mixing lubricating oil in hydrochlorofluorocarbon base refrigerant for functioning in place of chlorofluorocarbon is circulated. It comprises rollers 2 and a cage 3 for holding the rollers. The rollers are arranged in double row and the double row rollers are all crowned rollers.
