Key Terms for Bearings
Bearings are used for a wide array of mechanical purposes. There are several different kinds of bearings for these various uses. Front wheel bearings are recommended to be replaced every 30,000 miles. If you have rear-wheel drive, the front bearings should be checked. The following are key terms to help you understand the differences between bearing material and their practical uses.
Ball Bearings - This is used for relatively light loads. The load moves from the outer race to the ball to the inner race. This is a common bearing as it moves smoothly and effectively. The ball is sphere shaped. If the bearing is overloaded, the ball becomes deformed. This is also known as a wheel bearing. An example of its use is for the wheels of an inline skate.
Roller Bearings - This spreads the load out over a larger area than the ball bearing. This allows it to handle larger loads, but is not as capable of handling a thrust load.
Ball Thrust Bearings - Used for lower speeds such as a bar stool. It is intended for thrust loads.
Roller Thrust Bearings - Used for large rolling thrust loads such as gear sets.
Tapered Roller Bearings - Can handle large radial and thrust loads.
Thrust Load - The weight is parallel to the center of the axis.
Radial Load - The weight is perpendicular to the axis.
Linear Bearing - Any bearing that is used for the purpose of moving a load in one dimension. The bearings move the load in a linear fashion.
Bearing Pads - A pad that protects the bearings in the event of larger loads over long periods of time.
Bearings are sold through distributors all over the world. These steel bushings are made to help automotive and vehicle parts roll smoothly. They are commonly sealed into mechanical devices, skateboard wheels and engine parts all the time. Depending on the manufacturer, both cylindrical and spherical ball bearings are developed for sale. Distributors can then buy these steel bearings at low prices, and then sell them to consumers for a variety of applications. There are plenty of uses for materials like ball bearings, rails, ceramic bushings, and tapered spherical balls. Industrial environments utilize steel ball bearings that roll for mechanical devices. They are also used in aviation machinery, such as jet engines. One of the most commonly seen uses for ball bearings is on skateboards. This is a product that many people come in contact with on a daily basis. Motor vehicles are another type of machinery that often utilizes sealed steel bearings. These cylindrical parts are incorporated into automobile engines all the time. They assist other parts with spinning and running more smoothly. Although some of these tiny balls are barely the size of a needle head, they play a very crucial role. Your best bet for learning more about ball bearings for auto uses is either contacting a vehicle manufacturer or accessing the web to do a little research online. A mechanical professional who works on skateboards can also tell you more about cheap steel bearings that are used around the wheels. Just be sure to ask questions that pertain to your interests.
