Before knowing what bearings are the most popular types of bearing, we need to briefly introduce what bearings are. A rolling-element unit composed of rolling elements (balls, rollers, etc.) placed between the inner and outer steel rings. Not only can it drive the rolling between disconnected components, but also reduce the friction of the equipment during operation. According to the different rolling elements and the direction of force, there are many types of bearings. Deep groove ball bearings, thrust washer, sealed bearing, rod end bearing, journal bearing, etc. But as a professional technician, in my opinion, deep groove ball bearings are the most popular type. Initially, people found that placing a wooden ball between the wheel and the axle would not only speed up but also save time and effort. This is the prototype of the wheel bearing. With the passage of time and the continuous innovation of designers, it has high speed, high precision, easy installation and removal, and low price. So groove ball bearing is the first choice for all devices. If you want to know more details about types of bearing, please contact us, DAOQI PARTS will provide 7×24 hours online services.
