The difference between angular contact ball bearings and tapered roller bearings

Angular Contact Ball Bearings can withstand both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. High precision and high speed bearings typically take a 15 degree contact angle. Under the axial force, the contact angle will increase.

Tapered roller bearings are separate bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to a radial load, an axial component will be generated, so that another bearing that can withstand the axial force in the opposite direction is needed to balance.

In the case of a tapered roller bearing and an angular contact bearing, the roller is different, one is a sphere (point contact), and the other is a roller (line contact), of course, the line contact has a large load and a strong rigidity. Angular contact is mainly subjected to axial load; tapered roller bearings are subjected to axial and radial loads and transmit one-way axial loads. Angular contact bearings are generally used in areas where the pressure is low and the speed is high, such as a water pump. Stand up and wash. Tapered roller bearings are generally used in parts where the rotational speed is relatively low and the pressure is high, such as the automobile main shaft.
