Each ferrule of the structure deep groove ball bearing has a continuous grooved raceway having a cross-section of approximately one-third of the circumference of the equator of the ball.
Deep groove ball bearings are mainly used to withstand radial loads and also withstand certain axial loads.
When the radial clearance of the bearing is increased, it has the property of an angular contact ball bearing and can withstand the axial load alternating in two directions.
Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient, high speed limit and high precision, which is the preferred bearing type for users.
Deep groove ball bearings are simple in structure and easy to use. They are a type of bearing with large production volume and wide application range.
