A simple metal structure with smooth metal surfaces drives the rotation of a bearing. However, not all types of loads exert the same force on a bearing. Some types of loads are radial, while others are thrust. The type of bearing that you need on the type of load you place on it.
- Motor vehicles
Bearings are vital parts of any vehicle. Without them, many functions of a car would be impossible. Internal combustion engines have numerous moving parts, and bearings ensure that these parts rotate smoothly. In addition, electric motors are becoming more popular, which increases the demand for electric motor bearings. Electric motor bearings can be much smaller and lighter than conventional bearings, which improves drive train efficiency.
The primary function of bearings in motor vehicles is to reduce friction. The main function of bearings is to reduce the amount of friction between the rotating shaft and the part that supports the rotation. This reduces energy consumption. Some of the most common applications for bearings in motor vehicles include driveshafts, rock arm pivots, planetary gear sets, and air compressors.
- Office equipment
Bearings are used in all sorts of products, from computers and automobiles to office equipment. These small bearings help keep machines moving, and they also help reduce friction, which can reduce emissions and increase fuel efficiency. In office equipment, bearings are used in photocopiers, printers, and computers. Computer hard drives, for instance, use small ball bearings to keep them spinning.
The most common office equipment that uses bearings is printers and copiers. They contain needle and deep-groove ball bearings to conduct electricity at high temperatures while eliminating static electricity. Computer hard drives also use tiny ball bearings, as do other types of computer hardware.
- Home furniture and appliances
Bearings are used in a wide variety of home furniture and appliances, including televisions, air conditioners, dishwashers, bar stools, and can openers. They also are used in toys and other small electrical devices. Ball bearings are used in refrigerators, air conditioning units, dishwashers, ceiling fans, and kitchen drawers.
Most of your home appliances are stationary, but your tumble dryer uses bearings in the spinning drum to keep the appliance operating smoothly.
- Children’s toys
When it comes to children’s toys, bearings are a common feature. Bearings can help a variety of products move, including toy cars and bicycles. They can also help children with their fine motor skills. These bearings are ideal for toys that can be used as learning tools.
Many toys contain ball bearings for high performance and safety. A yo-yo, for example, uses bearings to reduce friction and make the toy spin more smoothly. Some yo-yos are made with ceramic bearings for added durability and performance.
- Space and scientific equipment
Bearings are used in a variety of applications, including scientific equipment and spacecraft. They enable tools to move, and they make complex machinery work. These versatile components have been used for hundreds of years. They come in various shapes, sizes, and materials, including steel, plastic, and ceramic. Chances are that you have used a bearing at some point in your life.
