SS6000 series deep groove ball bearings are simple in structure and easy to use. They are widely produced and applied. They are mainly used to bear radial loads and can also bear certain axial loads. When the radial clearance of the bearing increases, it has the function of an angular contact ball bearing and can bear larger axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high limiting speed. When the speed is high and thrust ball bearings are not suitable, this type of bearing can be used to bear pure axial loads.
