Auto water pump shaft bearing on the choice of material and heat treatment process

Shaft material selection of the bearing cage material selection of reinforced nylon 66, nitrile rubber seal ring generally USES, when using the environment temperature is greater than 120 ℃, it should choose fluorine rubber seal. Even bearing shaft heat treatment process: even the HSB pump shaft bearing of steel ball and roller are usually made from high chromium bearing steel, and shaft, the outer ring of material manufactured carburizing steel and high chromium bearing steel. Shaft materials manufactured carburizing bearing steel shaft hardness is generally 60 - race 64HRC； The hardness of high chromium bearing steel manufacturing shaft of 58 - usually 62HRC; Ball and roller hardness is 61 - 65HRC; Outer hardness is generally 60 - 64HRC。 Jiaxing bearing co. , LTD. Is a ( ） A specialized production automobile water pump bearings, shaft bearings, water pump bearings professional manufacturers, the company strictly in accordance with the quality of customer requirements and time to provide error-free, with cost-effective products and services, welcome to inquire. A: on the needle roller bearing in combination of needle roller bearing which is mainly the next several parts: ferrule needle roller bearing structure and tolerance to illustrate relevant tags: shaft bearing, axis bearing, axis related news even bearing fault even how to recognize the pump shaft bearing radial clearance original water pump bearing belongs to non-standard axle even even bearing shaft bearing is to simplify the bearing of double bearing even auto water pump shaft bearing is an important component of related products
