How long is the life of the car wheel hub bearing?The life of the
car hub is determined by various factors, but usually check the hub
wheel bearing after 50,000-80,000 kilometers:1. Comprehensively
consider factors such as the quality of the bearing itself, vehicle
driving conditions, mileage and load value;2. If the wheel bearing
quality is good, the road conditions are flat (no high-frequency
bumps), and the load is reasonable (not overweight), under normal
circumstances there will be no problems (noise) within 15,000
kilometers;3. The theory of the front and rear wheel hub bearings
of the car is 100,000 kilometers, but in the process of use, such
as wading in summer, there is no half-wheel drive, which will
directly affect the service life of the bearings. Therefore, in the
summer rainy season, open as shallow a road as possible;4. The
lubricating grease in the wheel hub bearing with good quality is
water-resistant, but the fine dust particles in the water will
accelerate the wear of the bearing, and the lubricating grease will
reduce the water resistance for a long time;5. After the wheel hub
bearing enters the water, oil, water and friction will make the
lubricating grease turn into an emulsion and lose the original
lubricating effect. The lack of lubricating grease in the bearing
will accelerate the wear of the bearing needle roller and the inner
and outer sleeve of the ball bearing, and the wheel bearing will
make noise after a long time it came out.Let TAIZHOU DONGNA share
the Ways to improve the service life of automobile wheel hub
bearings:Grasp the lubrication, installation and sealing technology
of the wheel bearing: first, when adding grease to the hub bearing,
it is necessary to fully calculate the amount of grease added,
avoid too much or too little, and ensure that the quality of the
grease itself is passed and there is no foreign matter inside the
grease. Specifically, the following aspects should be paid
attention to:(1) Clean the wheel hub bearings. During maintenance,
the hub bearings need to be thoroughly cleaned, and checked to
ensure that the bearings are not broken, shed, cracked, or ablated,
and then fully dry and free of moisture, otherwise the lubricating
effect of the lubricating oil on the wheel hub bearings will be
destroyed and the bearings service life will be reduced. (2) The
wheel hub bearings are well lubricated. While the hub cavity is
coated with a thin layer of grease to prevent rust, the wheel hub
bearing must also be fully lubricated. It is necessary to ensure
that the maintenance personnel squeeze hard by hand, and refill the
rotating bearing repeatedly until the roller bearing is filled with
grease, then the lubrication is complete, so as to ensure the good
lubrication state and normal wear of the wheel hub bearing.(3)
Strictly implement the maintenance procedures. During maintenance
work, maintenance personnel must strictly abide by the requirements
of technical specifications, clean, inspect, adjust, lubricate, and
fasten various mechanism components to ensure maintenance quality
and vehicle braking performance. Observe the operation status in
real time. When the vehicle is in operation, coordinate the driver
to pay attention to abnormal conditions such as abnormal noise,
high temperature, and low braking performance of the wheels,
collect information and deal with it in time to eliminate hidden
troubles.Secondly, to do a good job of bearing installation,
especially the adjustment of the wheel hub bearing clearance, the
bearing manufacturer should pre-set the clearance before leaving
the factory to avoid improper adjustment of the clearance during
subsequent installation. Thirdly, in order to prevent impurities in
the external environment from entering the bearing and causing
excessive friction, scientific and effective sealing measures
should be taken. Generally, the method of installing a sealing ring
is used. In addition to strict sealing, the material of the wheel
hub bearing sealing ring is also required. It must have sufficient
heat resistance, and the installation of the wheel bearing sealing
ring should preferably be pre-installed before leaving the
factory.Product description OEM auto wheel hub bearing for Toyota
