Angular contact bearings and deep groove ball bearings are all symbolic roller bearings, the difference between the two is mainly reflected in the type and load orientation of different design structures, installation requirements are different, different application fields and many other aspects, angular contact bearings are most suitable for applications requiring radial and significant axial load support, especially in the case of accurate alignment and load management is critical. Deep groove ball bearings are versatile, easy to install, and more suitable for high-speed applications where radial loads are the main concern. Both types of bearings have advantages, depending on the application requirements.
