GJP High Precision Automotive Water Pump Bearing with the size of 15.918X55X127MM is designed with “Ball-to-Roller” inner structure, and includes the parts of inner race, outer race, rolling elements, cages and what’s more, there is one shaft assemblied at this unit, it’s widely used on Mercedes Benz brand Bus, GJP design with good sealing and high loading capacity to satisfy our user’s bus or car’s requirements.
Automotive water pump bearing is a kind of bearing. The cage material is usually made of reinforced nylon 66, and the material of the sealing ring is generally made of nitrile rubber. When the requirements are higher, the fluorine rubber sealing ring can also be used.
In order to make the automotive water pump bearing fully play and maintain its proper performance for a long time, it is necessary to do regular maintenance. Early detection of failures and prevention of accidents through appropriate periodic inspections are important for improving productivity and economy.
1. Clean the automotive water pump bearing
When removing the automotive water pump bearing for inspection, first make a record of its appearance by means of photography. Also confirm the amount of remaining lubricant and sample the lubricant before cleaning the automotive water pump bearing.
The cleaning of the automotive water pump bearing is divided into rough washing and fine washing, and a metal mesh frame can be placed at the bottom of the container used. Use a brush, etc. in oil to remove grease or buildup during rough washing. At this time, if the automotive water pump bearing is rotated in oil, be careful that the rolling surface may be damaged by foreign matter. Carefully turn the automotive water pump bearing slowly in the oil during fine cleaning. The commonly used cleaning agent is neutral non-water diesel oil or kerosene, and sometimes a warm alkaline solution is used as needed. But no matter which cleaning agent you use, you should always filter it to keep it clean. Apply anti-rust oil or grease to the automotive water pump bearing immediately after cleaning
2. Check and judge automotive water pump bearing
In order to judge whether the removed automotive water pump bearing can be reused, it is necessary to focus on checking its dimensional accuracy, rotation accuracy, internal clearance, as well as the mating surface, raceway surface, cage and sealing ring. Regarding the inspection results, the judgment can be made by those who are accustomed to or proficient in automotive water pump bearings. Judgment criteria vary depending on mechanical properties and importance, inspection cycles, and the like. If the following damage occurs, the automotive water pump bearing must not be reused and must be replaced.
