Interpretation of the wheel bearing

Like many parts on the car wheel bearing has become more and more reliable, so that there is no failure before we tend to ignore it. To understand the cause of the problem, however, even if is the cause of aging, is meaningful for us SKF Bearings Inner Diameter http://www.cylindrical-roller-bearings.com/index.html.
Wheel bearing technology with the wheel itself has a long history. First the assyrians sidecar dates back to about 4000 years ago. The carriage with two "gaga" rattling wheels, can hear the sound of a carriage coming from a distance. Then the egyptians will be brass or bronze on the sidecar. They use copper embedded car axle hub and package. One of the earliest "grease cup" is filled stewing fat, butter or lard, and loosely set in the shaft head.
Ball bearing first appeared in more than 2000 years ago the ancient Romans, rotating platform used to support the ship, the rotating platform can be used for loading and unloading of goods can also be used to fight. Remember in primary school when I visited a Caesar s construction of hydropower station, the heavy water turbine in a ball on the seat of rotation, the shape of the seat is a bit like bowling alleys of ditches. Seat in the use of the steel ball to start the shell size, as the steel ball wear, constantly adding new steel ball until the steel ball wear to tennis great hour to remove it.
Many years ago in a rear wheel drive car on the front wheel of taper roller bearing gradually replaced the ball bearing. Although the manufacturing cost is higher, but overall life is longer than ball bearings taper roller bearing, the reason is that taper roller bearings are better able to withstand the axial load and stress, and larger than ball bearings allow the installation error of many. Cylindrical shape can make the roller full contact with the inner and outer race, the contact area and ball bearings with inner and outer race only two points. High guard of ball bearing roller contact with the seat of the oval, so more and more common.
