About mechanical bearings

Mechanical bearings is essential, especially in reducing the stress on the friction and mechanical equipment. Bearing outer metal surface of a metal roll into balls and metal balls.
Two kinds of load
There are two methods using a bearing - one of which is through a radial load. Radial load (e.g., a pulley), which is exerted on the weight of the bearing, thereby causing rotation of the ball therein. Another is the thrust load bearing is turned over to one side to bear the full load. Some bearings versatility, as they can withstand the radial and axial loads.
kind
Bearing due must bear the weight of the load varies. Some are designed for a single purpose, while others are combined radial and thrust.
ball. Ball bearings are common because they are radial and thrust loads together. For example, roller blade, weight is transferred from the outer region of the ball, and then transferred from the ball to the inside. Due to limited space and the ball is spherical, so that the rotation up more smoothly. However, a problem is that, when the bearing is overloaded, it will be deformed, thereby damaging the bearings in the process.
roller. A roller type withstand greater radial load, for example on a conveyor belt. As used cylindrical bearing is made, wherein the weight of the material distributed on the cylinder, so that the company easier to move a large amount of weight. Another form of roller bearing is a needle bearing, for smaller workstations.
Roller thrust. Thrust roller designed to withstand heavy thrust loads, for example an automotive transmission, helical gears, and other mechanical equipment required to support large heavy load.
Tapered roller. Tapered roller can often be found on the vehicle wheel, since they can support radial and thrust loads simultaneously.
Ball thrust. Thrust ball bearing is substantially only subjected to speed and weight of the thrust load less demanding. Examples of thrust ball bearings are those found in the bar stool and carousel.
specialized. These bearings are designed to meet the specific design requirements, such as a magnetic roller and giant roller. Electromagnetic bearings provide stability and support for high-speed devices. On the other hand, the giant roller for building structures, because they can quickly move heavy objects.
