1、Each ferrule of the structure deep groove ball bearing has a continuous grooved raceway having a intersecting surface of approximately one-third of the circumference of the equatorial circumference of the ball. 2、Deep groove ball bearings are mainly used to withstand radial loads and also withstand certain axial loads. 3、When the radial clearance of the bearing increases, it has the property of angular contact ball bearing and can bear the axial load alternating in two directions. 4、This type of bearing has a small friction coefficient, high speed limit and high accuracy. It is the preferred bearing type for users. 5、Mainly used in automobiles, tractors, machine tools, motors, pumps, agricultural machinery, textile machinery, etc. Features: 1.
